| 电缆直接接地箱，内部含有链接铜排、铜端子等，用于电缆护层的直接接地。 The cable direct grounding box contains copper bars, copper terminals and so on, which is used for direct grounding of cable 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。 The cable sheath protection grounding box and the cable sheath cross-connected grounding box contain cable sheath protector, link copper bar, copper terminal, etc., which are used for the protection grounding of cable sheath. 保护器采用ZnO 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 uses ZnO varistor as protective element. It has no series gap, good protective characteristic and excellent non-linear volt-ampere characteristic curve. It not only has the advantages of ceramic sleeve MOA, but also has excellent chemical stability, hydrophobicity and sealability, such as good electrical insulation, high dielectric strength, leak resistance, corrosion resistance, heat resistance, cold resistance, aging resistance and explosion resistance. |
