Standart: VDE 0276-626/4F
Description: Al conductors • XLPE insulation
Application:
The power cables with XLPE insulation for overhead lines - self-supporting type are designed for transfer, distribution and supply with electrical power in networks low voltage Uo/U 0.6/1 kV. In constructions for distribution networks these cable permit suspension on fasades and trees. They allow crossing of forest areas without cutting and maintenance of openings in the wood. The suspension and support of the whole bundle is carried out by the phase ( basic ) insulated current-conductive.
