BS 6485:1999 defines PVC-covered overhead conductors, ensuring electrical safety, durability, and mechanical strength for power transmission applications. It is widely used in UK and Commonwealth power infrastructure.
Conductor Material: Stranded conductors (typically aluminum or aluminum alloy).
Insulation: PVC (Polyvinyl Chloride) coating for weather and UV resistance.
Electrical Properties: High-voltage withstand capability (tested per standard conditions).
Mechanical Properties: Tensile strength and flexibility for overhead installation.
Dimensions & Tolerances: Specified thickness of PVC insulation and conductor diameter
Overhead power distribution lines (urban and rural networks).
Telecommunication line protection (where insulated conductors are required)
IEC 61089 (International standard for overhead conductors).
