AVVG cable decoding
What it is in technical terms can be identified from its letter designation, where
« A» - conductor-conductor made of aluminum;
« IN» - PVC insulating layer for each core;
« IN» - outer plastic shell;
« G» - lack of a protective cover.
AVVG cable design
Let's consider it in more detail:
- In the central part there is a core that conducts current.
It is aluminum, belonging to class 1/2, single or stranded. - The cores are enclosed in insulating sheaths; for these purposes, non-flammable and durable PVC compound is used.
- The outer protective sheath also consists of polyvinylchloride compound.

Installation work
AVVG is a cable that can be easily installed in almost any conditions, including horizontally, inclined or vertically located sections, in dry and damp rooms, in open areas, in areas with a risk of fire spread. It is not recommended to assemble the cable in conditions where mechanical impact on the device is possible, for example, in trenches: the cable can touch and damage working mechanisms or vehicles.
Designation in regulatory documents
The power cable produced at specialized plants for the production of electromechanical products in accordance with GOST 15150-69; 16442-80; 22483;5151-79.

Fire safety cable AVVG
The AVVG cable, equipped with a non-combustible plastic sheath, is actively used in industrial and domestic (residential) premises, where fire safety requirements are increased. It will hardly spread smoke and flames.
What is AVVG cable?
Hello dear reader! If you again looked at my website page, then you are interested in the question: what is an AVVG cable?
This question is often asked by novice electricians or just people who are faced with the problem of which cable to choose for different purposes. Let's try, as usual, in a simple way, to tell everything I know about the AVVG cable.
Let's start with where it is used: AVVG brand cable is used for transmission and distribution with constant laying at a nominal AC voltage 660 V and 1000 V frequency 50 Hz.
The AVVG cable is designed for operation in various premises and outdoors. Cable laying is carried out in different ways: in channels, pipes, trays, in the absence of tensile loads on the cable.
Design
In one of my articles, I already talked about. So, the AVVG cable is the same, we just pay attention to the first letter A. It says that the conductors are aluminum. They are single-wire or multi-wire, round or sector-shaped, PVC insulation. If you look at the cross view of the cable, you can see the insulated cores of 2, 3, 4 core cables are twisted into a core, the AVVG sheath is also plastic. What else I want to add, there are veins on the insulation color coding for your cable management convenience. Well, the letter G says that he is naked (without armor).
terms of Use
AVVG cable can be operated at a temperature environment from -50°С to +50°С. I would advise you to lay outdoors, in dry and wet industrial premises. The AVVG cable, which has a filling between the cores, can be laid in the ground under the condition of low corrosive activity of the soil and the absence of strong mechanical loads. It can be laid without preheating at a temperature not lower than -15°C. The minimum bending radius during laying must be at least 7.5 outer diameters of the cable. Does not propagate combustion with a single laying. Service life 30 years.
A little advice: I do not recommend laying the AVVG cable in the ground.
I tried to answer your question: what is an AVVG cable? Everything you need to know about the cable is described above. Select the cross section according to the power of electrical appliances. Write comments, additions to the article, maybe I missed something. Take a look at, I will be glad if you find something else useful on my site.
The price of the AVVG cable depends on the cost of the materials used in its manufacture, the current price of the AVVG warehouse cable is indicated in the price list section, discounts are provided on the volume of the order, check with the manager for the final cost.
Individuals and legal entities can buy AVVG cable by cash or bank transfer, shipment of AVVG warehouse cable is made within one day after payment.
Deciphering the AVVG marking:
A - aluminum wires.
B - PVC insulation.
B - PVC sheath.
G - does not have an armored cover.
Specifications of AVVG cable:
Climatic version of the cable AVVG - UHL and T, placement categories 1 and 5 according to GOST 15150-69.
The operating temperature range of the AVVG cable is from -50 °С to 50 °С.
Relative air humidity at temperatures up to 35°C - up to 98%.
Laying and installation of AVVG cable without preheating is carried out at a temperature not lower than -15 °C.
Permissible forces for pulling the AVVG cable along the laying route should not exceed 30 N/mm2 of the core section.
The service life of the AVVG cable is 30 years.
AVVG cable design:
1) Core - aluminum, single-wire or multi-wire.
2) Insulation - PVC.
3) Sheath - made of PVC compound.
Application of AVVG cable:
Aluminum power cable AVVG is designed for power transmission and distribution in stationary electrical installations for rated alternating voltage up to 1000 Volts with a rated frequency of 50 Hz. For laying single cable lines in cable structures and premises.
For group laying, the use of fire protection means is mandatory.
