Electricity North West (ENW) cable

As suggested by its name, Electricity North West supplies power to 2,400,000 homes across the North-West of England. DNO-approved cables of ENW specification, manufactured by approved suppliers are the only cables permitted for use on their section of the National Grid. In total, Electricity North West owns and maintains over 44,000km of underground cable and 13,000km of overhead line wire.

ENW 11kV and 33kV Cable Specifications

The Electricity North West 11kV and 33kV cable specifications are tightly controlled by the DNO. 

The 11kV cable is in triplex formation - three single cores wound together - with solid Class 1 Aluminium conductors. For 33kV, they are single core Class 2 rigid stranded Aluminium. They are sheathed in a robust abrasion and tear-resistant MDPE (Medium Density Polyethylene) as these cables are for external installation, usually in cable ducts.

For both cables, the screen cross-sectional area size is tailored to these specifications.
