Wires telephone distributive one-steam rooms are intended for the stationary hidden and open conducting of a telephone distributive network in rooms (TRV) and on external walls of the building (TRP).
DESIGN
CONDUCTING VEIN - copper, soft, single-wire.
ISOLATION - polyethylene for TRP, PVH plastic compound for TRV. Two in parallel the veins laid in one plane are isolated and separated one from another by the flat basis from the same material.

Climatic modification of a wire of the TRP UHL and T brand of category of placement 1, the TRV brands in a climatic modification of UHL of category of placement 3.1.
The electric resistance of a conducting vein to a direct current counted for 1 km of length and temperature 20ºС there has to be no more:
for a vein with a diameter of 0,4 mm - 148 Ohms;
for a vein with a diameter of 0,5 mm - 94 Ohms.
Working temperature: from - 60C to +65C (for TRP); from-40ºС to +65C (for TRV).
Wires of the TRV brands at single laying should not extend burning.
Installation of wires with polyethylene isolation has to be made at a temperature not below - 30C, wires with polyvinylchloride isolation - not below - 15C.
Isolation of wires of the TRV brand has to be resistant to deformation at a temperature of 65 °C and to cracking.
Color of isolation can be any. The wire intended for laying on external walls of buildings has to have svetostabilizirovanny isolation of black color.
Construction length - not less than 400 m, is allowed delivery by lengths not less than 40 m in number of no more than 10% of the total length of party.
Average service life of wires for external laying - 12 years, for internal laying - 25 years.
The average service life established by these specifications is provided on condition of observance of rules of storage, transportation, installation and operation.
