Product Overview
The PVC‑covered conductors have been developed primarily to give protection to telecommunication lines which are crossed by power lines and to give protection to the public from low voltage lines in case of accidental contact for short periods.
The PVC‑covered power lines have also been found useful in corrosive atmospheres and for preventing faults due to birds and trees.
The insulation thickness of Type 8 is intended for use where the operating voltage does not exceed 650 V r.m.s. between any two conductors or 250 V r.m.s. between any conductor and earth.
Application:
-
Crossing of telecommunication lines to guard against contact
-
Proximities to telecommunication lines to guard against contact
-
Lines (particularly service lines) accessible from buildings
Standard: BS 6485:1999 / BS 215 : Part 1
