当长线路高压单芯电缆运行时，由于电磁感应或设备故障，产生过电压，极易击穿电缆外护层套，形成单芯电缆多点接地故障，电缆护层保护器能有效限制电缆金属屏蔽层(金属护套)感应电压和设备故障过电压，更好的保护电缆的正常运行。电缆护层保护器主要用于缆护层保护接地箱和电缆护层交叉互联接地箱。聚氨酯软管 PVC软管 隔离墩模具 u型槽模具 护坡模具 pvc输送带 尼龙输送带 天津除甲醛 北京除甲醛
When the long line high-voltage single core cable operates, overvoltage is generated due to electromagnetic induction or equipment fault, which is very easy to break through the outer sheath of the cable, forming multi-point grounding fault of the single core cable. The cable sheath protector can effectively limit the induced voltage of the cable metal shielding layer (metal sheath) and equipment fault overvoltage, so as to better protect the normal operation of the cable. Cable sheath protector is mainly used for cable sheath protection grounding box and cable sheath cross interconnection grounding box.
电缆护层保护器的特点如下:
The characteristics of cable sheath protector are as follows:
1 优异的保护特性，有效限制电缆金属屏蔽层(金属护套)感应过电压和故障过电压。
1. The excellent protection characteristics effectively limit the induced overvoltage and fault overvoltage of the cable metal shielding layer (metal sheath).
2 伏安特性曲线平坦，通流能力大，保护特性好。
2. The volt ampere characteristic curve is flat, with large current capacity and good protection characteristics.
