Abstract

The invention relates to a traceless spliced cable protective jacket and a preparation method thereof, which belong to the technical field of electric power facilities, and solves the problem of providing a cable protective jacket which is high in strength, good in toughness, good in flame retardance, corrosion resistance and long in service life and a preparation method of the cable protective jacket. The protective jacket consists of sections A and sections B which are alternately arranged, the length ratio of the section A to section B is (2 to 4): 1, the section A and the section B which are adjacent to each other are connected in a fusion manner, and the outer surfaces of the section A and the section B are coated with protective paint C. The protective jacket is good in flame retardance, good in toughness, high in strength, resistant to sunlight, excellent in anticorrosion performance, and capable of effectively preventing the corrosion of acid and alkali salts; moreover, the protective jacket has good high temperature resistance, can effectively protect the cable for a long time and can prevent the safety potential danger; by virtue of the detection in test, the tensile strength of the protective jacket is greater than 35MPa, the elongation at break is 850 percent or above, the flame-retardant grade can reach grade A, and after being stored at the high temperature or soaked for a long time in acid and alkali salts, the surface of the protective jacket has no change.

Description

technical field [0001] The invention belongs to the technical field of electric power facilities, and in particular relates to a non-mark splicing cable protective cover and a preparation method thereof. Background technique [0002] In recent years, with the increasing development and popularization of the use of wires and cables in production and life, the demand for wires and cables has increased rapidly, and with the development of the economy, people have higher and higher requirements for their performance. The protective sheath of the cable is set on the outermost side of the cable, directly in contact with the external environment, and is closely related to the various performances of the cable. [0003] Cables have a wide range of applications, and often need to work in hot and humid climates or areas with severe acid-base-salt effects. However, general cable protective sheath materials are prone to aging, corrosion, and damage in hot and humid climates or in areas...
