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.
