AS/NZS standard 6.35/11kV XLPE Insulated MV Medium Voltage Power Cable
Description
Construction with higher fault current ratings are available on request. Suitable for static applications on the ground, inside and outside facilities, outdoors, in cable trenches, in water, and where the cables are not exposed to heavy mechanical stress and tensile strains. Because its dielectric loss coefficient is very low and remains constant throughout its service life, and because the XLPE material has excellent insulation properties and is firmly longitudinally spliced with the conductor shield and insulation shield of the semiconductor material (one molding), the cable operation has high reliability . Widely used in transformer stations, electric power plants and industrial plants etc.
A global manufacturer of medium voltage(MV) underground cable supplies a full variety of medium voltage(MV) underground cable and tailed electric cables from our stock.
Application
Electricity distribution or sub-transmission network cables are commonly used as the main supply for commercial, industrial and urban residential networks. Suitable for high fault level systems with current ratings up to 10kA/1sec. Construction with higher fault current ratings are available on request.
