Cable directly grounding box, copper bar, copper containing internal link terminals, for direct groundingcable sheath.

电缆护层保护接地箱和电缆护层交叉互联接地箱内含电缆护层保护器、链接铜排、铜端子等，用于电缆护层的保护接地。

Cable sheath grounding protection box and cable sheath cross connection grounding box with cable sheath protector, copper bar, copper terminal link, for the protection of the cable sheath grounding.

保护器采用ZO 压敏电阻作为保护元件，无串联间隙，保护特性好，具有优良的非线性伏安特性曲线。既具有瓷套式金属氧化物避雷器的优点，还具有电气绝缘性能好、介质强度高、抗漏痕、抗电蚀、耐热、耐寒、耐老化、防爆等优良的化学稳定性、憎水性、密封性。

The protector adopts the ZO varistor as the protective element, without series gap, and has good protection characteristics, and has excellent nonlinear volt ampere characteristic curve. Not only has the advantages of porcelain metal oxide arrester, also has good electrical insulation properties, high dielectric strength, anti leakage marks, anti electric corrosion and heat resistance, cold resistance, aging, explosion-proof excellent chemical stability, hydrophobicity and sealing.
