Problems solved by technology

[0002] In the heat-shrinkable tubing forming technology of the prior art, the molding of the heat-shrinkable tubing is done through moulds. In this way, a standard size mold can only correspond to the size of a heat-shrinkable tubing, but many occasions require oversized or not Standard-sized heat-shrinkable tubing, the existing technology is difficult to achieve these oversized or non-standard-sized heat-shrinkable tubing

Embodiment Construction

[0018] In order to better understand the technical solutions of the present invention, the embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] An embodiment of the present invention provides a method for manufacturing a heat-shrinkable sleeve. The heat-shrinkable sleeve is used to cover a power cable and can be used to insulate and protect the power cable. The manufacturing method of the heat-shrinkable sleeve comprises steps:

[0020] A: Bend both ends of the heat shrinkable sheet;

[0021] The heat shrinkable sheet is made of radiation cross-linked crystalline polyolefin insulating material, wherein the radiation cross-linked crystalline polyolefin insulating material includes high-density polyethylene sheet, high-pressure polyethylene, linear polyethylene, polyethylene or polyethylene - ethyl acrylate. These materials have the ability to become larger when heated for the first time and bec...

Abstract

The invention discloses a method for manufacturing a thermal shrinkage casing. The method comprises the following steps of: bending edges at the two ends of a thermal shrinkage sheet respectively; interlocking the two bent edges to perform hot pressing; and sewing the bent edges which are combined together by the hot pressing. The method for manufacturing the thermal shrinkage casing has the advantage of manufacturing the thermal shrinkage casing of any diameter by using the thermal shrinkage sheet in the sewing way.

Description

technical field [0001] The invention relates to the technical field of electric power materials, in particular to a method for manufacturing a heat-shrinkable sleeve applied to electric power. Background technique [0002] In the heat-shrinkable tubing forming technology of the prior art, the molding of the heat-shrinkable tubing is done through moulds. In this way, a standard size mold can only correspond to the size of a heat-shrinkable tubing, but many occasions require oversized or not Standard-sized heat-shrinkable sleeves, it is difficult to realize these oversized or non-standard-sized heat-shrinkable sleeves with existing technologies. Contents of the invention [0003] The invention provides a method for manufacturing a heat-shrinkable sleeve, which is used to process and manufacture a heat-shrinkable sleeve with any diameter. [0004] In order to achieve the above object, the present invention provides the following technical solutions: [0005] A method for ma...
