AI Technical Summary

Problems solved by technology

[0002] Mineral insulated cables are very different from conventional cables. The sheath of mineral cables is made of stainless steel, and the insulating material between the core wires is silica powder. During the stripping process, silica powder is easy to absorb moisture, resulting in reduced insulation performance. The core wire has no independent insulating layer and is easy to short circuit. Therefore, the integration of mineral cables and electrical connectors is a very complicated technology. However, since mineral cables themselves do not have any organic materials, compared with conventional organic cables, they are more resistant to radiation and high temperature. , long life, corrosion resistance and mechanical strength of the skin have absolute advantages

[0003] The conventionally designed insulating support material for electrical connectors is plastic, but the mechanical strength and dielectric properties of this type of insulating support will decrease to varying degrees under high cumulative doses of radiation and high temperature environments, which may lead to failure of electrical connectors
