Application

TPPShv/ТППШв cable is used in local telephone network and in telecontrol with frequency, pulse-duration and pulse-position modulation of signals up to 1048 kHz and voltage up to 225V for a frequency of 50 Hz or DC voltage of 315V. Cables are used for outdoor and indoor laying, including explosive and combustible environment and premises with chemically active substance within maximum permissible concentration, building walls, in a cable structure and cable-conduit line. Also it can be used under extra air-pressure.

Application of closures for the cable:

Connecting closures – MIKS;
Compression closures – SSK, VSSK;
Compression closures – SSK (arm), VSSK (arm);
Connecting and splicing closures MS, MR;
Gas dam – GNS, GNS (for mining works);
Gas dam – GNSK.
