Cable grounding system

The cable grounding system includes cable grounding box, cable grounding protection box (with sheath protector), cable cross interconnect box, sheath protector and so on. Generally, the main problem is that the box is not well sealed, and the water leads to multi point grounding, which leads to the excessive induction current of the metal sheath. Besides, the parameter selection of the sheath protector is unreasonable or the quality is not good. The unstable Zinc Oxide crystal is also easy to cause damage to the protective layer protector.

Structure of medium voltage cable
The components of high voltage cable from inside to outside include conductor, insulation, inner sheath, filler (armor) and external insulation. Of course, the armored high voltage cables are mainly used for ground burying, which can resist high strength compression on the ground and prevent other external damage.
