AI Technical Summary

Problems solved by technology

However, during the construction process, when the cable is threaded, the traction steel cable or the outer sheath layer of the cable will rub against the inner wall of the power tube, and the inner surface of the power tube will be worn, and the glass fiber in the inner wall of the power tube will be hung out, forming a continuous winding on the cable. Fibrous filaments will eventually cause the cable to be stuck, making it impossible to carry out cable construction

Abstract

The invention relates to the technical field of electric power tubes, particularly to a composite electric power tube and a preparation method thereof. The electric power pipe comprises a lubricationinner layer and a protection outer layer, wherein a glass fiber reinforced layer is also arranged between the lubrication inner layer and the protection outer layer, the lubrication inner layer comprises the following raw materials in parts by weight: 100 parts of PVC, 10-15 parts of a filling modifier, 4-5 parts of a stabilizer II, 0.5-1 part of an outer lubricant, 0.5-1 part of an inner lubricant and 0.5-1 part of a compatilizer II, wherein the filling modifier is prepared by preparing a carrier from PVC / PA66 composite fibers and loading modified nano cubic boron nitride / wollastonite particles on the carrier. The prepared composite electric power tube has good wear resistance and a relatively small friction coefficient, labor is saved in the using process, and damage to the power tube and a cable is small.

Description

technical field [0001] The invention relates to the technical field of power tubes, in particular to a composite power tube and a preparation method thereof. Background technique [0002] The development of electric energy is related to the national economy, the people's livelihood and national security. With the continuous and rapid development of my country's economy and society, the demand for electric power has also entered a period of rapid growth. Recently, with the development of urban planning and construction and the cleanliness and beauty of the city, high-voltage wires are required to be buried underground. Due to the high voltage of the high-voltage cable, it is easy to generate high temperature due to heat generation or instantaneous accidental short circuit, so people usually use plastic pipes, metal pipes or glass steel pipes as the sheathing material of high-voltage cables. [0003] Metal pipes have poor corrosion resistance, and their service life is generall...
