KGN cable: technical characteristics, decoding

How is it deciphered?

The marking depends on what the cable is made of and what characteristics it is equipped with. KGN transcript:

K - power wire;
G - has high flexibility;
N - the insulating layer is made of nairite rubber.

What the product looks like
Nairite rubber is commonly called vulcanized rubber. During vulcanization, zinc and magnesium substances are used, and the main advantage of the cable will be increased resistance to various chemicals, including acetone, white spirit, petroleum substances, acid, and various types of oils. And also, the big advantage of rubber is its high strength and resistance to mechanical damage. Even at critically high temperatures, the rubber structure does not deteriorate and does not burn.

When marking a wire, after the KGN there may be a dash and a few more letters that mean resistance to weather conditions.

KGN cable technical characteristics

The KGN-T cable functions well in tropical areas because it can cope with the influence of mold and fungi. The KGN-HL product can be used at abnormally low temperatures.

Conductor design

The cable is copper. The structure is multi-wire, round in shape.
The flexibility of the cable is 5, all this is confirmed by GOST 22483.
The insulation is rubber, it corresponds to the markings of cables and wires.
A special layer is applied over the core; it prevents the insulation from sticking.
The shell is made of rubber, which does not burn and is not afraid of moisture, which adds increased performance.
The KGN cable is multi-core, so all the wires are twisted. The twisting pitch cannot exceed 16 diameters.

Peculiarities

The main condition for accepting a new participant into the CTG is that the results of its activities comply with the standards of Article 25.2 of the Tax Code of the Russian Federation. The decision to accept a new member must be signed by all group members. In addition, it is necessary to make changes to the existing agreement on the creation of the Group of Companies.

It is also signed by all participants, including the new member. If the performance indicators of the new company do not correspond to the data specified in the Tax Code of the Russian Federation, then government authorities may refuse to register the changes made.

Scope of application

This product is mainly used to provide electricity to mobile consumers (cars and machinery) from DC networks.

The resistance of the insulating sheath to water, lubricants and various aggressive chemicals allows the cable to be used in mines, cellars, enterprises with high humidity, submarines, as well as in agriculture. Cables with a small cross-section can be used to connect household and household appliances.

Such a cable can be used for laying electrical wiring, but it must be remembered that it cannot be bent to sharp corners (the minimum radius must be greater than 8 diameters).

Laying outdoors is allowed, with an operating temperature range from −30°C to +45°C. An additional advantage will be the coloring of the wires. This will help you avoid confusion when connecting.

Wire KGN 5×10

Purpose and operating conditions

The KGN wire is intended for connecting non-stationary electrical mechanisms to an alternating current network with a voltage of up to 660V and a frequency of up to 400Hz or a direct current with a voltage of up to 1000V.

Cable KVVGNG LS

The maximum temperature at which long-term operation of the conductor is possible is 75°C.

Thanks to the hermetic insulating sheath made of Nairite rubber, cable products can be used for the installation of electrical networks laid in aggressive environments, as well as in dry or wet rooms (mines, ship rooms, basements).

Attention! The sheath material is quite sensitive to ultraviolet radiation, so when using KGN for laying networks outdoors, additional protection is necessary.

The service life of KGN is 2.5 years, KGN-T is 4 years.

How to choose a wire

Before purchasing, you must rely on the conditions of use and permitted loads during the energy transfer process. For a classic voltage of 220 V, you can use a wire with two cores, with a cross-section of 1-6 square meters. mm.

If a PE conductor with protective grounding is used, then a three-core cable must be selected. The last wire is used for grounding.

In electrical networks with voltages of 380 and 660 V, three-wire products with additional grounding are used. To calculate the required cross-section, you need to be guided by the load in the network (calculate the number of devices and their power).

If conductors with a smaller cross-section than necessary are used, overheating may occur. Because of this, the outer sheath will melt and the wire will fail. When purchasing cable products, you need to visually examine them and check for damage to the insulation.

Proper indoor storage

The same inspection must be carried out after transporting the cable or immediately before installation. This can be done by testing the wire.

You must also ask for a certificate of conformity before purchasing. It must indicate the plant itself, the length of the cable and the date of its production, and a seal about passing the tests. Correct cable products are manufactured in accordance with GOST standards.

When checking the certificate, you must pay attention to the name of the manufacturer, which must be written in full, as well as the expiration date of the document.

It is advisable to choose high-quality factories that have been on the market for more than 10 years. Therefore, before purchasing, you can read reviews about the best sellers of cable products.

How to conclude an agreement to create a consolidated group

The agreement on the creation of the CG indicated the following important points:

item;
list of parties to the agreement and their contact/registration information;
company name - OUKG;
information about the responsibilities of each member of the group and separately OUKG (timing and procedure for execution), as well as information about the responsibility that arises due to failure to fulfill the terms of the contract;
the validity period of the CG, and, accordingly, the contract;
the amount of information provided by each member to determine the tax base and pay income tax.

You may find the tax information contained in the article “What is the object of taxation for income tax?” useful.

The agreement on the creation of a corporate group was subject to mandatory registration with the tax authority. In order to register it, the OUKG had to collect a complete package of documents. It included:

the contract itself (in 2 copies);
statement of establishment signed by all members of the CG;
documents confirming the powers of the signatories of the agreement;
accounting and financial documents confirming that all members of the group have the right to create a group of companies (information requiring confirmation is specified in subparagraphs 2–3, 5 of article 25.2 of the Tax Code of the Russian Federation).

The data that needs to be confirmed is certified by the OUKG. This list includes copies of financial statements, payment slips confirming the payment of taxes and excise taxes.

All these documents had to be submitted by October 30, so that starting next year, group members could work and pay taxes within the CG. After submitting documents to the tax authority, a decision was made within a month to register the agreement or refuse it.

If the Federal Tax Service has discovered correctable violations that can be corrected within the allotted month, the OUKG is notified of this and is obliged to eliminate them in a timely manner.

If all formalities regarding compliance by participants with the requirements of Art. 25.2 of the Tax Code of the Russian Federation, and there is also a full package of documents, the agreement on the creation of the CG is registered. Within 5 days, 1 copy of the agreement is issued with a note about the registration.

Next, the Federal Tax Service that carried out the registration notifies all territorial tax authorities in which the participants of the group are registered about their status. The same notifications are sent to the INFS, where separate divisions of companies that are members of the CG are registered.

If all the described formalities were observed, the CG was recognized as created on January 1 of the year that occurred after the registration of the agreement on the creation of the CG.

Laying rules

This wire model has a fairly short service life. It cannot be installed to power stationary objects. But, if you exclude harmful effects on the cable and install it permanently in accordance with all the rules, then it can work for a long time without losing its properties.

When installing electrical wiring, you must pay attention to the following parameters:

if the cable is placed through walls, then it must be provided with additional protection in the form of corrugation;
wire bends should not be more than eight diameters, otherwise the product may be damaged;

Loader for transportation and handling

indoor installation can be performed using the open method, fixation is carried out using clamps, clips, clamps;
in open areas, during outdoor installation, the cable must be laid in protective trenches and cable ducts;
when installing the product in the air, a support rope is used, to which the wire is attached using special rings;
the rope is installed in the places of support fastenings.

Explanation of markings

First of all, you need to tell us how the abbreviation stands for. According to existing standards, the decryption is as follows:

K – cable;
G – flexible;
N – the insulating layer is made of nairite rubber (non-flammable).

As you can see, the markings are quite simple and clear. There are several more varieties, namely KG-HL (cold climate) and KG-T (tropical), but we will definitely talk about these brands separately in future publications.

You can familiarize yourself with the technical characteristics of the KG cable in the corresponding article!

Problems using the cable

The main problem during installation can be accidental damage to a thin layer of insulation. As a result, when the wire operates, a short circuit and fire occur. To prevent this from happening, it is necessary to keep the product as far as possible from stones and tools.

If the temperature during operation rises to 80 degrees or higher, you must immediately turn off the power to the cable, otherwise a fire or short circuit may occur.

Technical characteristics of the KGN cable

The climatic solution for oil-resistant flexible power wire is U. According to the current GOST, it belongs to the first and fifth categories.

The temperature range at which the product is allowed to operate is from minus thirty to plus fifty degrees Celsius.

Installation work is carried out if the air temperature does not drop below minus thirty degrees.

The permissible heating temperature of the wire over a long period of time is up to plus seventy-five degrees.

Fire safety classification - according to GOST.

The guaranteed service life of the product is up to four years from the date of manufacture of the product.

Storage and transportation rules

During storage, the cable drum should stand and not lie down. It is allowed to store such wires outdoors under a canopy so that they are not exposed to precipitation.

During storage, the ends of the wire must be protected from external influences (ultraviolet rays, water, chemicals). Wires with fiber, enamel protection and sheathing made of other moisture-absorbing compounds should be stored only in warehouses.

When opening the cable package, you need to place plywood or a board under the drum.

Note! If the packaging is damaged, it is not recommended to use this product.

The room temperature should not be lower than 15 degrees. Humidity is not allowed, because it causes fungi and mold to grow. It is also necessary to check whether there are any rodents in the warehouse.

From time to time it is recommended to check the product for mechanical damage. Since if they are, this can significantly reduce the service life and also lead to unpleasant consequences.

The company was founded in the 50s of the last century. There are more than 35,000 thousand brand sizes available. The manufacturer has fairly reasonable prices for the products. We have experience in supplies for large nuclear power plants. In 2015, the plant won one of the Russian competitions as the best new product of the year. The factory provides the largest guarantee of all the above-mentioned enterprises. Over the past few years, branches of the plant have appeared in different cities of the country.

GC "Sevkabel"

This is one of the first cable factories in Russia. The plant was founded back in 1879 by a German scientist. The company produces more than 25,000 thousand types of mark sizes. The factory has an impeccable reputation. At the end of 2021, the company plans to complete its modernization and introduce new technologies for the production of cable products.

Various macro sizes

In conclusion, it should be noted that it has many advantages. Therefore, every year it is increasingly used in everyday life. This cable is perfect for connecting mobile electrical machines.

Advantages of KGN

The amount of income tax and the scope of tax control are reduced:

CTG participants summarize profits and losses from the results of activities of each of them - that is, they consolidate the tax base;
Transactions concluded between KGN organizations are not subject to control over transfer education. Exception: transactions the subject of which is an extracted mineral resource - the subject of mineral extraction tax taxation using an interest rate.

Thus, we can conclude that the introduction of the institution of taxpayer consolidation in Russia has a positive trend, since it is aimed at optimizing profit taxation, as well as simplifying tax administration.
