APPLICATION
The cables are designed according to the standards CEI 20-13 and IEC 60502. The insulation is made of high module HEPR polymer, extruded together with the inner and outer semi-conducting layers: the triple co-extrusion and cross-linking system gives the cable a very high safety on duty and reduces the partial discharge effect. The cables are suitable for energy supply at nominal voltages higher than 1 kV (up to 30 kV) and for connections between medium voltage substations and low voltage transformers. Upon specific request, the cables might be manufactured with armour in steel, whenever the laying or working conditions require a mechanical protection. This result is achievable with wires, with flat wires, with tapes, or with braid. LSZH Low smoke zero halogen sheathed version.
