ZMS Cable and Accessories

  Metal shield, as an important structure of medium voltage power cable , will pass capacitive current under normal operation of the cable and act as a pathway for short circuit current in the event of a short circuit. It also shields the electromagnetic field generated when the cable is energized in the insulating core to reduce electromagnetic interference to the outside world. Copper tape can also be used for gap packaging. Single-core cable shielding with copper tape nominal thickness of not less than 0.12mm. The copper wire shield is composed of loosely wound soft copper wire, the surface of which is tightly bound with counter-wound copper wire or copper tape. The average gap between adjacent copper lines is not more than 4mm. The shielding method of copper wire and copper tape winding can structurally improve the disadvantages of the copper tape winding shielding method. There is neither an oxidation layer generated by overlapping copper tape nor strong bending and hot and c...
