ARE4H5E 18/30kV SK1 (SHOCK PROOF 1)

Single core cable with aluminium conductor, reduced thickness cross-linked polyethylene (XLPE) insulation, aluminium tape screen, reinforced polyethylene (PE) based outer sheath. Longitudinal and radial watertightness, shock resistant.

Application:

Suitable for fixed installation indoor or outdoor laying in air or directly / indirectly buried, also in wet location. “ Shock Proof” SK1 has a very good shock resistance characteristics. The special outer sheath provides an excellent protection against impact and mechanical abuse during the lifetime of the cable. “Shock Proof” SK1 cable performances has been evaluated against mechanical protection by the abrasion test and the impact test included in HD 620-10-I3 standard. This type of cable can be directly buried without additional protections because it is comparable to an armoured cable.
