Abstract

The invention belongs to the field of an electric material and discloses a cable sleeve pipe. The cable sleeve pipe is prepared from the following raw materials: polyethylene resin, chloric ether resin, phenolic resin, chlorinated paraffin, borax, sepiolite, glass fiber, magnesium hydroxide, palygorskite, zinc borate and sodium dodecyl sulfate. The cable sleeve pipe provided by the invention has high acid, alkali and salt resistance and high high-temperature and cold resistance.

Description

technical field [0001] The invention belongs to the field of electric power materials, and specifically discloses a cable casing. Background technique [0002] Cable sleeve is a heat-shrinkable sleeve commonly used for insulation protection on cables. The main material of this type of product is PE. After two processes of irradiation cross-linking and heating expansion, it has the function of heat shrinkage, and the shrinkage ratio is about 3:1. , ranging from 50-350mm in diameter, can be used as heat-shrinkable inner sheath, outer sheath, and outer insulating and waterproof cable sleeve in cable accessories. The main purpose of the cable sleeve is to be used as a cable sheath to protect the cable from external damage and ensure the safety of electricity. The power cable sleeve is divided into buried type and ground type. In the last century, cable sleeves made of metal materials were generally used to protect cables; with the continuous development of the material field,...
