Construction Application area Technical data Calculated data

Conductor

Copper, single-wire or multi-wire core , of circular or sector-shaped form, of the 1 or 2 class according to GOST 22483, with the cross-section from 1.5 to 1000 mm²

Insulation

Halogen-free polymer composition.

Core arrangement

Insulated conductors of 2, 3, 4 and 5 core cables twisted in cable core. The sealed cables are twisted with water blocking elements.

Inner sheath

It’s extruded, superimposed over twisted insulated conductors with the filling of exterior gaps between the conductors of halogen-free polymer composition. Cables of type N2XH with the cross section up to 50 mm² and more superimposed over inner sheath with the fiber-glass or mica-tape.

Screen

For cables of types PPGEng(A)-HF and PPGEgng(A)-HF the screen is made in form of lapping with copper tapes or copper wires and a spiral taping with a copper tape.

Separation layer

For cables of types PPGEgng(A)-HF the separation layer is made additionally by winding a layer of tapes of water blocking materials.

Cable armoring

For cables of types PBPng(A)-HF is laid helically with two steel, galvanized tapes.

For cables of types PBPgng(A)-HF it is possible to lay the winding or longitudinally the tapes with water blocking materials.

Cable sheath or jacket

It’s made of halogen-free polymer composition.

The cables are designed for transmission and distribution of electric power in stationary electric installations on alternating voltage 0,66 and 1kV and frequency 50 Hz.

The cables are used for group installation of cable lines and circuits and control of the equipment, electrical wiring in office premises, equipped with computer and microprocessor appliances in kindergartens, schools, hospitals and for cable lines of entertainment complex and sports facilities.

The class of fire hazard of the cables according to GOST 31565 П1б.8.1.2.1.

The cables of types PPGgng(A)-HF, PPGEgng(A)-HF, PBPgng(A)-HF are sealed with water blocking elements (threads, braids and tapes) are used in conditions of high humidity. For manufacturing of the cables water blocking materials are used. They allow the cables to be resistant for longitudinal penetration of moisture.

Nominal voltage, kV		0,66 or 1
