PVC Covered Conductor (BS 6485)

Introduction

Application
Two types of PVC-covered conductors for Overhead power lines.Type 8 is intended for use only where the operating voltage of the power lines does not exceed 650 V r.m.s.between any two conductors or 250 V r.m.s. between any conductor and earth. Type 16 is intended for use only where the operating voltage of the power line exceeds 650 V r.m.s between any two conductors or 250 V r.m.s. between any conductor and earth, but does not normally exceed 11 kV r.m.s. between conductors or 6.6 kV r.m.s. between any conductor and earth.
Specification
