Problems solved by technology

[0003] However, the existing wires used in the fields of iron and steel, metallurgy, thermoelectricity, chemical industry, aviation, aerospace and other fields near 1000°C ultra-high temperature have low heat resistance due to structural reasons, and it is difficult to withstand long-term high-temperature environments. It is easy to be damaged during use, which affects the safety and reliability of use

Abstract

The invention discloses a high-temperature-resistant 1000°C electric wire, which includes multiple sets of conductors, and also includes a tape layer and a braided shielding layer. The conductor is covered with an insulating layer to form an insulated wire core, and three insulated wire cores are combined and covered with a braided shielding layer. The braided shielding layer is covered with an elastic heat insulation layer and a loose tube from the inside to the outside to form the main core, and a reinforcing core is arranged between the multiple main cores, and the multiple main cores are all set in the tape layer, and the tape The layer is covered with a braided heat-resistant layer, an inner sheath, a braided armor layer and an outer sheath in sequence from the inside to the outside, and the tape layer is filled with heat-insulating and flame-retardant particles; by setting a ceramic silicone rubber insulating layer outside the conductor , can effectively improve the fire resistance of the conductor insulation layer. Compared with the oxidized mineral insulation layer of the transmission, it has excellent fireproof, flame retardant, low smoke, non-toxic and other characteristics. By filling the tape layer with heat-insulating and flame-retardant particles , can play a good heat insulation and flame retardant effect, and can effectively improve the structural stability and weighing performance of the cable.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a high-temperature-resistant 1000°C electric wire and a preparation method thereof. Background technique [0002] With the improvement of equipment performance requirements for aerospace equipment, there are requirements for special equipment such as small size and light weight. As the connection wires for electrical equipment and instruments used in spacecraft, it is required to be small in size, adapt to various harsh environments, have a large carrying capacity and strong overload capacity, and require cables to have good mechanical and physical properties, electrical properties and easy laying. The cables should have high temperature resistance. , fire resistance, environmental protection, flame retardant, softness and other characteristics, safety guarantee requirements [0003] However, the existing wires used in the fields of iron and steel, metallurgy, thermoelectri...
