本实用新型涉及一种聚酰亚胺和芳纶绝缘H级封闭式电机引接线,其由金属导体、内编织层、外编织层及绕包层组成,金属导体外部由内至外依次包裹内编织层、绕包层、外编织层,所述内编织层、外编织层均由芳纶编织而成,绕包层是由聚酰亚胺制成的薄膜条带缠绕内编织层而成。本实用新型采用聚酰亚胺作为绕包层的材料,聚酰亚胺有良好的化学稳定性,耐高温性能好于PET;而芳纶不但具有良好的化学稳定性、耐高温性能,还具有良好的力学性能。编织后的电缆产品完全适合在封闭式电机的高温、高压的制冷剂和润滑油的场合下应用。专利申请号:CN201120563497.X公开号:CN202473356U申请人:天津市华之阳特种线缆有限公司
The utility model relates to a polyimide and aramid insulation H-class enclosed motor lead wire, which consists of a metal conductor, an inner braid, an outer braid and a wrap around, wherein the outer part of the metallic conductor is covered sequentially from inside to outside The braid, the wrapping layer, the outer braid, the inner braid and the outer braid are woven by aramid fiber, and the wrapping layer is made by winding a braid of a film strip made of polyimide. In the utility model, polyimide is used as the material of the wrapping layer, the polyimide has good chemical stability and high temperature resistance is better than PET; and the aramid not only has good chemical stability and high temperature resistance, but also has Good mechanical properties. Braided cable products are perfectly suited for applications where high temperature, high pressure refrigerants and lubricants of enclosed motors are required.
