1. 不同的概念
铠装电缆: 它由不同材料的导体安装在带有绝缘材料的金属套管中, 并加工成弯曲的实体组合.
非铠装电缆: 无铠装保护层电缆, 由几根或几组电线组成,每组至少两根绞合电缆, 每组电线绝缘, 通常围绕一个中心 Twisted. 整个外层面包有高度绝缘的覆盖层.
这 氧化锌避雷器 uses zinc oxide resistance as the main component, which greatly improves the voltammetric characteristics of the arrester and increases the through-current capability. When the arrester is in normal operation, the voltage flow through the arrester current is only microampere. When the overvoltage is received, the excellent non-linear characteristics of the arrester play a good role.
A lightning arrester is mainly used to protect electrical equipment from lightning intrusion overvoltage and operating overvoltage on its power equipment insulation damage.
