Power cables (0,6/1 kV) with XLPE insulation and HFFR sheath with concentric conductor

(N)A2XCH

APPLICATION

In earth, ducts, on support brackets, in dry and wet conditions etc., where one does not expect mechanical damages and the cables are not exposed to the mechanical tensile strain. In urban networks, industrial plants, electric power plants and other electricity consumers and for connection of control devices in industry, traffic etc., where fire prevention safety measures are requested, for eleveted electricity and thermic strains.
