Abstract

The invention discloses a shielding type corrosion-resistant communication cable. The cable comprises a protective outer layer and a shielding layer. An outer insulation communication core wire, a copper mesh layer and an inner insulation communication core wire are sequentially arranged in the shielding layer; and the protective outer layer is prepared from the following raw materials in parts byweight: 70-80 parts of polyvinyl chloride, 10-14 parts of nitrile rubber, 20-27 parts of nylon 4T, 5-8 parts of maleic anhydride grafted polyethylene, 2-4 parts of a stabilizer, 3-5 parts of a lubricant and 3-4 parts of an antioxidant. The shielding type corrosion-resistant communication cable has a good electromagnetic shielding effect, a good electromagnetic shielding effect is achieved betweenthe outer insulation communication core wire and the inner insulation communication core wire, mutual interference is avoided, and the requirement for use in the environment with serious electromagnetic interference can be met; and in addition, the corrosion resistance is good, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a shielded corrosion-resistant communication cable. Background technique [0002] A cable is usually composed of several or several groups of wires, a rope-like cable twisted by several or several groups of wires (at least two in each group), each group of wires is insulated from each other, and often surrounds a The root center is twisted and the entire outside is covered with a highly insulating covering. [0003] The cable has the characteristics of internal energization and external insulation. There are many types of cables. According to the requirements of different application environments, different cables will be used. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all compo...
