Application

These power cables are used for overhead lines at specific environmental conditions like strong wind, ice, snow and when the route of the cables is placed over mountains and forests. Cable's construction enables smaller destination between two phases, opposites against strong wind and tolerates bigger mechanical and electrical loads provoked by fallen trees. The primary advantage of cross linked PE is despite the two conductors are close too much to each other because of the wind, the line isn't fallen out. The ice sheath over the cross linked PE sheath doesn't retain as long as over the bare conductor.

Construction

• The conductor is rope according MKS N.C1.402 (DIN 48 201/6) of wrapped wires of AlMgSi-E alloys according MKS N. C1.401(DIN 48 200/6) . The rope is compacted.

• XLPE outer jacket, black coloured, XI3, according MKS N.C0.195(DIN VDE 0207/22), with content of carbon black at least 2%, low temperature and UV resistance.
