电缆接地箱的构造 Construction of cable grounding box 电缆直接直接接地箱,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 is directly grounded in the box, which contains the link copper bar, copper terminal, etc. for the direct grounding of the 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。 Cable sheath protection grounding box and cable sheath cross interconnection grounding box contain cable sheath protector, link copper bar, copper terminal, etc., which are used for protective 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。 ZnO varistor is used as the protection element of the protector, which has no series gap, good protection characteristics and excellent nonlinear volt ampere characteristic curve. It not only has the advantages of the metal oxide arrester with porcelain sheath, but also has the excellent chemical stability, hydrophobicity and sealing properties, such as good electrical insulation performance, high dielectric strength, leakage resistance, anti-corrosion, heat resistance, cold resistance, aging resistance, explosion-proof, etc. |
