Abstract
The utility model discloses a three-core cross linked polyethylene (XLPE) insulating and shielding cable which comprises three sets of insulation cores. The insulation cores comprise conductors and insulating layers sequentially wrapping outside the conductors, and the three sets of the insulation cores and filling ropes are twisted to form a cable core which is wrapped by a band to form a band layer. The band layer is wrapped by a shielding layer, and the shielding layer is extruded by an inner sheath which is extruded by an oversheath. Compared with the prior art, the three-core XLPE insulating and shielding cable has excellent insulating and shielding effects, and is high in use safety and simple in structure.
