Insulating material for transmission line

Abstract

The invention belongs to the field of electric materials, and discloses an insulating material for a transmission line. The insulating material for the transmission line is prepared from, by weight, 1-2 parts of magnesium oxide, 1-2 parts of antimonous oxide, 1-2 parts of oleamide, 1-2 parts of borax, 2-3 parts of triphenyl phosphate, 2-3 parts of zinc borate, 2-3 parts of glass fiber, 3-4 parts of palygorskite, 4-6 parts of stearic acid, 5-7 parts of egg shells, 5-7 parts of kaolin, 8-10 parts of aluminum nitride, 8-10 parts of triallyl cyanurate, 12-15 parts of chlorinated polyethylene, 16-20 parts of ethylene propylene diene monomer and 16-20 parts of hydrogenated acrylonitrile butadiene rubber. The insulating material for the transmission line is good in insulating property and flame retardant property, excellent in mechanical property, good in corrosion resistance and suitable for various environments, the application range is greatly widened, and the service life is greatly prolonged.

Description

technical field [0001] The invention belongs to the field of power materials, and in particular relates to an insulating material used for power transmission lines. Background technique [0002] Power transmission is achieved by using a transformer to boost the power generated by the generator, and then connecting it to the transmission line through circuit breakers and other control equipment. According to the structural form, transmission lines are divided into overhead transmission lines and cable lines. The overhead transmission line is composed of line towers, wires, insulators, line fittings, guy wires, tower foundations, grounding devices, etc., and is erected above the ground. The most important component of a transmission line is the power cable. 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, ...

Problems solved by technology

[0003] No matter from the perspective of mechanical properties, thermal fire chemical resistance and disaster protection, the outer insulation material of the cable plays a vital role in protecting the internal material from damage and maintaining its normal operation. In the specific application process, the cable The outer insulating material must be able to resist sunlight, UV radiation, ozone aging, and chemical erosion, and at the same time, it can still guarantee or temporarily guarantee its normal operation in the case of accidental disasters. With the frequent occurrence of electrical fire accidents, the resistance of wires and cables The burning problem has gradually attracted the attention of all countries in the world; when the cable burns, it releases a large amount of smoke and toxic and corrosive gases, which are dangerous factors in fires, which hinder people's safe evacuation and fire fighting work, and cause serious losses of life and property. At the same time, with the development of the communication industry, the automobile industry and the computer industry, especially in many occasions such as aviation wires, automobile wires, high-temperature instrument cables, and oil drilling platform cables, it is increasingly necessary to use flame-retardant, thermally stable, and heat-resistant materials.
