Custom AL / PE Insulated Aerial Bunch Cable 3 Core IEC 60502 Certification

 

 

Description

 

The aerial Bundled cables designed for overhead distribution lines have an insulated neutral messenger made of AAAC, which the insulated aluminium phase conductor are helically wound over it. Cables are rated at 0.6/1(1.2)kV and conform to IEC60502.

 

Construction

 

  1. Conductor:

 

a)Phase - The phase conductor shall be of H68 Condition aluminium conductor and compacted circular stranded.

 

b)Neutral or messenger - The Neutral or messenger conductor shall be of aluminium alloy conductor and compacted circular stranded.

 

  1. Insulation:

 

The phase, neutral conductors shall be extruded with polyethylene(PE) as insulation.
