Problems solved by technology

[0006] Existing power cables are often buried in the ground during use, and the cable skin will be oxidized after long-term use, which will cause aging and damage to the cable skin, resulting in short-circuit phenomenon, and long-term heavy objects squeeze and be attacked by rodents and ants The sheath will break when chewed, which will prevent the cable from working properly

Abstract

The invention discloses an environment-friendly rat-proof and termite-proof plastic insulating power cable which comprises the following raw materials in parts by weight: 100-120 parts of PVC resin, 5-10 parts of oxidation-resistant filler, 5-10 parts of reinforcing filler, 3-5 parts of a flame retardant and 1-3 parts of a lubricant. An oxidation-resistant filler and a reinforcing filler are prepared in the preparation process; the oxidation-resistant filler can capture free radicals formed in the oxidation process of a polymer; a chain reaction with a destructive effect on free radicals is avoided; and capable of decomposing hydroperoxides, a stable non-active product is generated; mixing with rubber matrix, the oxidation-resistant filler can be uniformly mixed and distributed in the basebody; the anti-aging performance of the cable is not reduced after the cable is used for a long time, the service life of the cable is prolonged, when the reinforcing filler is blended with a rubbermatrix, active groups on the surface of the glass fiber enable the reinforcing filler to be uniformly dispersed in the rubber matrix, and the impact resistance of the cable is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of cable preparation, and in particular relates to an environment-friendly rodent-proof and ant-proof plastic insulated power cable. Background technique [0002] Power cables are an important carrier of power transmission. With the acceleration of the transformation of urban power grids, the number of power cables laid in urban power grids has increased. Especially in central urban areas, the ratio of power transmission lines using cables has continued to rise. Compared with overhead lines, although the investment cost of underground cables is higher, it has the advantages of reliable operation, does not occupy the ground area, and does not hinder the view. Moreover, due to the presence of corrosive, flammable or explosive items in some places, only underground cables can be laid. . Therefore, in densely populated cities, using cable power supply is the current and future development trend. [0003] Exist...
