Suitable for installation in the ground, in protective conduits, cable ducts, in open air, for power stations, industry and distribution boards or low-voltage distribution systems.

The design is specially used in 5-conductor TN-S systems with separate neutral (N) and protective earth (PE). This enables an EMC-optimised supply network for reduced electromagnetic interference.

Due to the cross-linked conductor insulation, particularly suitable for higher temperatures in the case of a short-circuit or overload. The PE sheath of the BayEnergy® LV mains cables is particularly robust and distinguishes itself with excellent mechanical properties and increased thermal compressive strength.

Type Designation Codes

G conductor insulation, elastomer cross-linked
