产品应用：
电缆护层保护接地箱适用于35kV-220kV高压电力电缆系统，可保护电缆的外护层绝缘免受过电压的损害。该产品内部主要采用电缆护层保护器，产品整体结构简洁、密封可靠，产品内部导体为铜排连接，产品外壳为不锈钢材料焊接，绝缘件经防潮处理，导体连接件全部镀锡，并采用螺栓压接，安装简单，便于预防性试验时电缆金属护层与保护器之间脱开。保护接地箱可安装于户外及预埋地下运行，不受各种异常气候的影响。
Suitable for 35kV-220kV high voltage power cable system, can protect high voltage cable outer sheath insulation from overvoltage damage. Adopt cable sheath protector, the integral structure of the product is simple, reliable sealing, product internal conductor is copper bar connection, shell is welding by stainless steel materials, insulation parts with moistureproof processing, conductor fittings all tin plating, and adopt the bolt pressure welding, installation is simple, easy to disconnect between cable metal protecting laye and protector when preventive test.Protective earthing box can be installed at outdoor running, not affected by all kinds of abnormal climate。
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。
