Rat-proof and ant-proof inflaming-retarding environment-friendly power cable

Abstract

The invention discloses a rat-proof and ant-proof inflaming-retarding environment-friendly power cable. A cable core of the power cable is formed by twisting a plurality of insulation wire cores. Each insulation wire core is composed of a conductor, an inner mica tape fireproof layer and an insulation layer from inside to outside. Gaps among the wire cores are provided with a packing layer. A lining layer is arranged outside the packing layer. A metal shielding layer is arranged outside the lining layer. A water-blocking polyester band, a waterproof isolation layer, an outer mica tape fireproof layer, an outer band wrapping layer, a restrictive coating, an insulation layer and rat-proof and ant-proof synthesis neoprene tape are arranged outside the metal shielding layer. The rat-proof and ant-proof synthesis neoprene tape is wrapped with an inner rat-proof and ant-proof synthesis neoprene sheath, the inner rat-proof and ant-proof synthesis neoprene sheath is longitudinally wrapped with an embossed alloy aluminum plastic composite belt, and the outmost layer is wrapped with an outer rubber sheath.

Description

technical field [0001] The invention relates to a cable and a manufacturing method thereof, in particular to a rodent-proof and termite-proof high-strength rubber-plastic composite cable used in harsh environments such as industry, agriculture, commerce, construction, mines, etc. and methods of manufacture thereof. Background technique [0002] With the rapid development of my country's modernization, underground cables have become an inevitable trend. Using buried power cables instead of overhead open wires has many advantages, such as stable power transmission, safety and reliability, and saving metal and wood. Especially in the southern coastal areas of my country, there are many typhoons and heavy salt spray, which often cause disconnection of the guide rod of the open line, seriously affecting communication and power supply. The above-mentioned effects can be avoided by realizing the undergroundization of cables. However, if the cable is buried in the ground, it is n...

Problems solved by technology

[0005] The following problems exist in the traditional anti-rat and anti-termite production technology: 1) The poor performance of the material itself leads to poor insulation and mechanical properties; 2) Poor insulation and sheath elasticity, large compression deformation, and low strength; 3) Anti-rat, anti-termite, Poor insect resistance; 4) weather resistance, heat aging resistance, poor cold resistance; 5) flammable, good flame retardancy; 6) unreasonable structure, the armor layer cannot form a smooth round surface, there are gaps and edges
