Abstract

The invention belongs to the technical field of power equipment, and particularly relates to a dual-layer composite cable protection pipe and a preparation method thereof. The cable protection pipe comprises a dual-layer structure, wherein an inner layer of the cable protection pipe is a glass fiber reinforced plastic pipeline; an outer layer of the cable protection pipe is a polypropylene pipeline; the glass fiber reinforced plastic pipeline is made from glass fiber reinforced plastic, epoxy resin, polymethylmethacrylate, brucite, polyacrylonitrile-based carbon fiber nano-silica and the like; the polypropylene pipeline is made from polypropylene resin, low-density polyethylene resin, an initiator, an antioxidant, calcium carbonate and an orange pigment; hot processing compounding is performed by using different thermal expansion performance of the two pipelines. A composite pipeline has superior performance of the two pipelines, and has the advantages of cold resistance, aging resistance, corrosion resistance, high anti-pressure ability, easiness in wiring and the like; moreover, the production cost and transportation cost of the pipeline are lowered, and a higher economical value is achieved.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to a double-layer composite cable protection tube and a preparation method thereof. Background technique [0002] Cable protection tube is also known as cable tube, power cable tube, power row tube, power cable protection tube, etc. The cable protection tube is mainly installed at the intersection of communication cables and power lines to prevent short-circuit accidents caused by disconnection of power lines, causing communication cables and steel wire ropes to be charged, so as to protect cables, switches, core boards, and the whole machine from being burned out. Magnetic field interference also plays a certain role in isolation. [0003] Cement cable protection tubes are gradually eliminated due to poor resistance and heavy weight. Today's power protection tubes are mainly polypropylene tubes and glass steel tubes. Compared with glass steel pipes, polypro...
