摘要
交联绝缘电线电缆具有优异的电气性能,良好的运行安全性能和热过载机械特性以及安装运行维修简便等优点。电线电缆绝缘材料的交联机理是采用物理或化学方法,使高分子绝缘材料由线性分子结构转变成三维网状结构,由热塑性材料变成热固性绝缘材料,从而提高了绝缘材料的耐老化性能,机械性能和耐环境的能力。
Cross- linked insulated wires and cables have excellent electrical properties, good safety performance and thermal overload mechanical properties, easy installation operation and maintenance, etc. Crosslinking mechanism of wire and cable insulating material is to use physical or chemical method, the high polymer insulating materials by linear molecular structure into a three- dimensional reticular structure, made of thermoplastic materials into thermosetting insulation materials, so as to improve the aging resistance of the insulating material, mechanical properties and resistance to environment the ability.
