电缆接地箱主要有三种：电缆护层直接接地箱，电缆护层保护接地箱，电缆交叉互联保护接地箱。

There are mainly three kinds of cable grounding boxes: the cable sheath, the direct grounding box, the cable sheath, the protection grounding box, the cable cross connection protection grounding box.

1电缆护层接地箱/接地保护箱

1 cable shield grounding box / grounding protection box

电缆护层直接接地箱，内电部含有、连接铜排、铜端子等，用于电缆护层的直接接地,内部无需安装电缆护层保护器。电气绝缘性能好、介电强度高、抗漏痕、抗电蚀、耐热、耐寒、耐老化、防爆等优点及良好的化学稳定性、憎水性、密封性。电缆护层直接接地箱分单相直接接地箱、三相三线直接接地箱（平时简称的电缆护层接地箱）、三相六线直接接地箱。

The cable protection layer is directly grounded, the inner electric part contains, copper and copper terminals, etc. for the direct grounding of the cable protection layer, and there is no need to install the cable protector inside. Good electrical insulation, high dielectric strength, leakage resistance, corrosion resistance, heat resistance, cold resistance, aging resistance, explosion proof and so on, and good chemical stability, hydrophobicity and sealing. The direct grounding box of the cable protection layer is divided into single phase direct grounding box, three phase three line direct grounding box (usually for short cable protection layer grounding box), and three phase six wire direct grounding box.

三相六线直接接地箱

Three phase six wire direct grounding box

电缆护层保护接地箱内含有电缆护层保护器、连接铜排、铜端子等，用于电缆护层的保护接地。主保护器采用ZnO电缆护层保护器，密封结构采用硅橡胶密封，达到较高的密封防水要求。全部采用铸铝或不锈钢外壳，导体连接件采用镀锡铜排，并采用螺栓压接，安装简单，便于预防性试验时电缆金属护套与保护器间脱开。保护接地箱可安装于户外运行，不受各种异常气候的影响。电缆护层保护接地箱分单相接地保护箱、三相三线接地保护箱（平时简称的接地保护箱）、三相六线接地保护箱。(公众号：输配电线路)

The cable sheath protection grounding box contains cable sheath protector, connecting copper bar, copper terminal and so on, which is used for the protective grounding of cable sheath. The main protector adopts ZnO cable sheath protector, and the sealing structure adopts silicone rubber seal to achieve higher sealing and waterproofing requirements. All of them are cast aluminum or stainless steel shell, the conductor connector is plated with tin copper, and the bolt is pressed, and the installation is simple. It is convenient for the cable metal sheath to be removed from the protector during the preventive test. The protective grounding box can be installed in outdoor operation without any abnormal weather. The cable sheath protection grounding box is divided into single phase grounding protection box, three-phase three wire grounding protection box (usually referred to as grounding protection box), and three-phase six wire grounding protection box.

2电缆护层交叉互联箱

2 cable shield cross interconnected box

电缆护层交叉互联保护接地箱内含有电缆护层保护器、连接铜排、铜端子等，用于电缆护层的保护接地。电缆护层交叉互联保护接地箱外壳及连接螺栓全部采用不锈钢材料，耐腐蚀性能优良。

The cable interlayer protection interconnect box contains cable sheath protector, connecting copper bar, copper terminal and so on, which is used for the protective grounding of cable sheath. The cross connection protection layer of the cable sheath is made of stainless steel and the corrosion resistance is excellent.

电缆护层交叉互联保护接地箱导电连接全部采用螺栓压紧结构，安装简单，便于预防性试验时拆装。内部保护器选用硅橡磁针氧化锌电阻片保护器。导电连接件全部镀锡处理，导电性能可靠。绝缘支撑件均采用防潮处理。(公众号：输配电线路)

The cross connection protection layer of cable sheath, the conductive connection of the grounding box is all made of bolt pressing structure, and has simple installation, which is convenient for disassembly and assembly during preventive test. The internal use of silicone rubber needle protector Zinc Oxide resistance sheet protector. The conductive connectors are all tinned, and the conductivity is reliable. The insulation support is moisture-proof. (public number: transmission and distribution line)

3电缆护层保护器

3 cable protector

电缆护层保护器应用于单芯电力电缆线路中，限制电缆金属护层上的感应过电压，确保电缆护层绝缘不被过电压击穿。(公众号：输配电线路)

The cable protector is applied to the single core power cable line, limiting the Induced Overvoltage on the metal shield of the cable to ensure that the insulation of the cable shield is not broken through by overvoltage. (public number: transmission and distribution line)

电缆护层保护器采用ZnO压敏电阻作为保护元件，没有串联间隙，保护特性好，具有优良的伏安特性曲线。

The cable sheath protector adopts ZnO varistor as protection element. It has no series gap, good protection characteristic and excellent volt ampere characteristic curve.
