Single-conductor cables with aluminum or copper veins, with isolation from the sewed polyethylene, with longitudinal and cross sealing, in a cover from the halogen-free polymeric composition which is not extending burning. Cables conform to the MEK 60840, MEK 60332-1 Or 60332-3 standards.

Conducting vein 

Copper or aluminum, multiwire, condensed also corresponds to a class 2 on MEK 60228. Conducting veins with a section from 1000 to 2500 mm2  are carried out from 5 sector preparations - segments. Upon the demand of the customer of a vein can be made with longitudinal sealing.

The screen on a vein 
From electroconductive peroksidnosshivayemy polyethylene

Isolation 
From peroksidnosshivayemy polyethylene

The screen on isolation 

From electroconductive peroksidnosshivayemy polyethylene

Dividing layer 
From the electroconductive water blocking tapes

Metal screen 

Poviv copper a provolok over which the copper tape is spiralno imposed. Notes:

- depending on the size of currents of short circuit and time of their course the section of the copper screen which value makes a reservation at the order is defined;

- upon the demand of customers the screen from copper a provolok can switch on fiber-optical modules of temperature

Dividing layer 

From the electroconductive water blocking tapes

Thermal barrier 
From electroconductive steklolent

Cross sealing 

From the laminated alyumopolimerny tape strongly welded with an external cover.

External cover 
From the halogen-free polymeric composition which is not extending burning

Semiconducting layer 
From a semiconducting halogen-free compound; in cables with an index (p); serves for control of integrity of a cover of a cable after laying

APPLICATION

Cables are intended for transfer and distribution of electric energy in three-phase networks on the rated alternating voltage of 64/110 kV of the frequency of 50 Hz with a glukhozazemlenny neutral and direct link with an air-line or without it on routes with an unlimited difference of levels. Cables are intended for stationary single laying and group laying (for cables with an index ng (A)-HF with a section up to 800 mm2) in electrical units of public and industrial constructions where there are requirements for restriction of influence of corrosion and active gases, and also stationary laying in soil, in trenches, polyethylene pipes or concrete trays, and also in partially or completely flooded cable constructions and production rooms.
