ARE4H5EEX 18/30kV SK2 (SHOCK PROOF 2)

Three single core cables in triplex formation with aluminium conductor, reduced thickness cross-linked polyethylene (XLPE) insulation, aluminium tape screen, double 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” SK2 has a very good shock resistance characteristics. The two special outer sheaths provide an excellent protection against impact and mechanical abuse during the lifetime of the cable. “Shock Proof” SK2 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.
