Triplex 11 kV cable for BS 7870 – 4.10 Product Overview
Our MV cables are designed for distribution and generation utilities, offering outstanding mechanical and electrical performance. Built to withstand demanding installation environments, they can be safely laid directly in the ground or routed through buried cable ducts.
Applications:
Power distribution from mains to local sub-networks
Suitable for both copper and aluminium conductor designs
Not intended for overhead supply (see aerial bundle cables for such applications)
Voltage Ratings:
6.35/11kV
12.7/22kV
19/33kV
Cable Construction
Each cable is manufactured with precision, using Class 2 Copper or Aluminium conductors, ensuring conductivity and durability. Insulation is provided by Cross-linked Polyethylene (XLPE) for high thermal stability, with additional features to enhance performance:
-
Metallic Screen: Copper wire screen for fault protection and shielding
-
Sheath Options: Medium Density Polyethylene (MDPE) or Low Smoke Zero Halogen (LSZH) for fire-safe environments
-
Waterblocking: Optional conductor and longitudinal water-blocking designs available for enhanced reliability in challenging conditions
-
Core Variations:
-
BS7870-4.10: Single core cables up to 19/33kV
-
BS7870-4.20: Three core cables rated at 11kV
-
