电缆护层保护器的特点如下：

The characteristics of the cable protective layer 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 excellent protection characteristics, effectively limiting the wire metal shielding layer (metal sheath) induction overvoltage and fault overvoltage.

2 伏安特性曲线平坦，通流能力大，保护特性好。

2 volt - ampere characteristic curve is flat, the flow ability is big and the protection characteristic is good.

3 硅橡胶外套，采用独有的界面粘和技术和整体一次成型工艺，密封性能好，安全防暴，免维护。

3 silicone rubber coat, using unique interface bonding and technology and integral molding process, good sealing performance, safe and anti riot, maintenance free.
