Abstract

The invention discloses an improved silane crosslinking cable. The improved silane crosslinking cable comprises a copper core, a silane crosslinking insulating layer and an ethylene-vinyl acetate thermal contraction layer, wherein the copper core is located at the center of the improved silane crosslinking cable, the silane crosslinking insulating layer is arranged on the outermost layer of the improved silane crosslinking cable in an extruded mode and is 2mm thick, and the ethylene-vinyl acetate thermal contraction layer is arranged between the copper core and the silane crosslinking insulating layer in a wrapped mode and is 0.1mm thick. The improved silane crosslinking cable effectively overcomes the shortcoming that the silane crosslinking insulating layer is poor in adhesive force and plays a role in reducing thermal contraction.

Description

[0001] Technical field [0002] The invention relates to the field of power cables, in particular to an improved silane cross-linked cable. Background technique [0003] At present, cross-linked cables have become one of the fastest growing cables in the past decade due to their high working temperature, excellent insulation performance, and high overload resistance. The cross-linking methods of cross-linked cables are usually divided into peroxide cross-linking, There are three types of radiation cross-linking and silane cross-linking. Among them, silane cross-linked cables have the advantages of less equipment investment, strong adaptability and simple process, and have become the main varieties of cross-linked cables. However, because the silane cross-linked insulation layer of the silane cross-linked cable has the characteristics of poor adhesion and large heat shrinkage, the heat shrinkage index of the silane cross-linked cable often exceeds the requirements in the relevant c...
