Abstract

The invention discloses a construction mode of a power cable. A spiral beryllium bronze wire for returning is located in a hollow opening. A male connector penetrates through and is placed on the spiral beryllium bronze wire for returning. The male connector comprises a head part 1 and a head part 2, face to face. The head part 1 is inserted into a positioning opening. 2,2,4,4-tetramethyl-1,3-cyclobutanediol, polyacetal resin, polycarbonate, 2 to 6 parts by weight of asbestos, attapulgite, zinc dialkyldithiophosphate and xylene are fed into a mixer and mixed uniformly to form an intermediate material 3; a cable sleeve is sleeved on a metal wire to form the cable. The detect in the prior art that a power cable made of a cable material having Martin thermal stability lower than 50 DEG C anda Vicat softening point lower than 64 DEG C is far from being suitable for the occasions where the Martin thermal stability and the Vicat softening point are highly required is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a construction method of a power cable. Background technique [0002] In recent years, my country's power cable material production enterprises have made great progress, especially some private enterprises, which have greatly improved in terms of production scale, product structure adjustment and new product development in line with market demand. However, the traditional power cable materials have problems such as insufficient flame retardancy and excessive heavy metals, which hinder their application. [0003] Therefore, a widely used environmental protection cable material with application number 201711319504.X, application date 2017.12.12 and patent name "environmental protection cable material" was invented, which is made of the following components in parts by weight: PVC 50-80 parts of resin, 25-35 parts of polyvinyl chloride, 10-15 parts of aluminum oxide powder, 5-...
