Conductor: copper, single wire, circular, with the diameter: 0,40; 0,50; 0,64; 0.70 mm.

Insulation: of polyethylene.

Twisting: two insulated conductors are pair twisted by unidirectional twisting, pairs are twisted in bundles of five pairs or a core of  a five pair cable  with unidirectional twisting around the central string which is made of water blocking material, the elementary beams are twisted in a core. The elementary beams have the distinctive coloring of the fastening threads.

Belt insulation consists of:

 •tapes from water blocking material, over which the control conductor of soft copper or tinned copper wire with insulation made of porous polyethylene is laid;

 •PET tape;

 •tapes of water blocking material.

Screen: aluminum polyethylene tape imposed by winding or longitudinally with an overlap, there is a copper tinned contact wire laid longitudinally under the screen.

Sheath: halogen-free polymer composition.

Armoring (for TVBPBbPng(A) – HF): superimposed helically with a gap with two steel galvanized tapes.

Jacket (for TVBPBbPng(A) – HF): halogen-free polymer composition.

The cables are intended for operation in local primary communication networks with rated voltage of remote power up to 225 and 145 V AC, 50 Hz or voltage up to 315 and 200 V DC respectively, as well as for installation in ducts of cable systems, in tunnels, collectors, in mines, in construction of underground, internal walls of buildings, including high-rise mixed-use buildings or inside of buildings, including for use outside the hermetical systems in nuclear power plants of classes 3 and 4 according to the classification OPB-88/97 NP-001-97 (PNAEG -01-011-97).

The cables are manufactured in climatic design B, category of location 4 according to GOST 15150 – 69.

Cable of mark TVBPng(A) – HF is designed for group laying in domestic electrical installations , and in buildings with mass stay of people, including in multifunctional high-rise buildings and building complexes, taking into account the volume of combustible load in conditions of absence of mechanical stress.

Cable of mark TVBPBbPng(A) – HF is designed for group laying in domestic electrical installations, and in buildings with mass stay of people, including in multifunctional high-rise buildings and buildings complexes, taking into account the volume of combustible load in conditions of  presence of mechanical stress.

Fire hazard class according to GOST is 31565-2012 – P 1B.8.1.2.1
