PVC-covered conductors for overhead power lines

BSI BS 6485:1999

This British Standard specifies requirements for PVC-covered conductors for overhead power lines. Two types of PVC-covered conductor have been standardized by the designation of minimum thickness of covering as follows:

  1. Type 8: 0.8 mm;

  2. Type 16: 1.6 mm.

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. Under these operating conditions, it is suitable for:

  1. crossings of telecommunication lines to guard against contact;

  2. proximities to telecommunication lines to guard against contact;

  3. lines (particularly service lines) accessible from buildings.

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. The earthing of the neutral point of the system through an arc-suppression coil is not precluded, if arrangements exist for clearing earth faults without undue delay.

Under these operating conditions, type 16 is suitable for crossings of telecommunication lines and proximities to them.
