Description

Technical Field

[0001] The utility model relates to the technical field of cable application, in particular to a waterproof and anti-knock cable. Background Art

[0002] Cable is a rope-like cable made of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a center, with a highly insulating covering on the outside. Cables usually consist of four parts: conductor, insulation layer, shielding layer and protective layer, and have the function of transmitting power or information. There are many types of cables, including power cables, communication cables, control cables, instrument cables, coaxial cables, optical cables, etc., which are widely used in various fields such as power, communication, construction, industry, and transportation.

[0003] The device with the publication number CN220252893U is a waterproof and anti-knock cable, wherein the mica tape is wrapped around the conductor, the insulating layer is wrapped around the mica tape, the conductor, the mica tape and the insulating layer form a wire core, one or more wire cores are wrapped around by a first wrapping layer, the shielding layer is arranged on the second wrapping layer, and further comprises an inner lining layer and a third wrapping layer, the inner lining layer wraps around the first wrapping layer, the material of the inner lining layer is ceramicized polyolefin, the second wrapping layer is wrapped around the inner lining layer, the third wrapping layer wraps around the shielding layer, the third wrapping layer comprises an aluminum-plastic composite tape for waterproofing, and the outer sheath wraps around the third wrapping layer.
