The 3-core power cable is consisted of 3 single core cables which are laid up together with the ground core in triplex formation

 

Applications 

for public power distribution networks 12/20KV. It is suitable for underground installation, direct buried, in cable ducts and in air. Suitable for installations in which CPR Dca-s2,d2,a2 cables are specified.

 

Design

Each single core cable is consisted of Aluminium conductor, semiconductive conductor screen,  XLPE insulation, semiconductive insulation screen, aluminium tape for metallic screen with water protection and LSZH outer sheath.

The single core cables are laid up together with an aluminium lead sheathed ground conductor.

 

Core identification: by numbers 1, 2, 3 on the outer sheath of each single core cable
