Medium-high voltage oil-resistant rubber shielding cable

Abstract

The invention belongs to the technical field of cables, and particularly relates to a middle-high voltage oil-resistant rubber shielding cable. The cable comprises a conductor, an inner skin, filler, a Y-shaped isolation belt and an outer skin; the inner skin is fixedly connected to the outer side of the conductor, the inner skin comprises two layers including an inner shielding layer and an insulating layer, and the inner shielding layer wraps the outer side of the conductor; the insulating layer wraps the outer side of the inner shielding layer, the number of the conductors is three, the conductors are separated by the Y-shaped isolation belt, and the outer skin wraps the outer side of the Y-shaped isolation belt. According to the shielding cable, the filler is arranged in the gap between the outer skin and the Y-shaped isolation belt, the filler is the nylon rope, the tensile property of the shielding cable can be improved in the longitudinal direction, and in the transverse direction, the filler is provided with the rope knots, so the filler is not prone to deviating from the position, the stability of the internal structure of the cable is improved, and meanwhile, the buffering and damping functions are achieved; and the cable is worthy of universal application and popularization.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a medium and high voltage oil-resistant rubber shielded cable. Background technique [0002] Medium and high voltage (such as voltage level > 6000 volts) rubber sheathed cables, rubber semi-conductive shielding materials for conductors and insulation. At present, medium and high voltage rubber sheathed cables are widely used products at home and abroad, such as GB12972, MT818, GB12706 And other national or industry standards have requirements for conductors and insulation shielding materials. Although the technology contained in cross-linked polyethylene or polyolefin shielding materials at home and abroad is quite mature, they are not suitable for thermosetting rubber sheathed cables, because cross-linked polyethylene or polyolefin shielding materials have thermoplastic properties and are not suitable for thermosetting cables. Rubber type cable. There are also manufacturers ...
