工作原理:
该产品的核心部件为电缆护层保护器,保护器由非线性优良的氧化锌电阻片组成。在正常工作状态时,电阻片为高阻值,而当过电压波侵入时,电阻片是低阻,即使流过很大的电流,保护器两端电压值仍被限制在允许范围内,从而有效地保护了电缆外护层绝缘,使其免受过电压的损伤。
The core components of this product is cable sheath protector, protector is composed of zinc oxide nonlinear resistance slice. In the normal working state, resistance is high resistance, when the voltage wave invasion, resistance is low resistance. even when large current flows, protection voltage value is limited in the allowable range, so as to effectively protect the cable outer sheath insulation, make it from the damage of overvoltage。
