Distribution cable KRVPM

The KRVPM cable is intended for fixed installation in buildings and structures.


It is used in telecommunication and computer networks, in the frequency range up to 16 MHz, a cable with a twist other than a pair is used for signaling and control of instrumentation, in the frequency range up to 100 kHz, with an operating voltage of alternating current not exceeding 145V.

Structure
  1. Current-carrying copper conductor with a diameter of 0.4 mm, 0.5 mm or 0.8 mm;
  2. PE conductor insulation;
  3. PVC compound sheath.
The cable core design can be performed in two ways:
  • twisted single conductors;
  • conductors pre-twisted into symmetric pairs.
