Lightweight thin insulation overhead cable insulation without internal semiconductor shield. b) approximation is neither guarantee and do not check the value GJX galvanized steel cable offer, but in the design and technology required to be fully considered. Insulation resistance uninsulated galvanized steel wire shielded cables GJX sales price, insulation resistance test should be carried out. Test on a tray cable. At room temperature, the cable is not less than 1h galvanized steel wire immersed in water, applying a voltage (80 ~ 500) V DC voltage stabilization time should not be less than 1min, not more than 5min. Ordinary insulation and cable insulation resistance should be not less than 1500MΩ · km line of protection (PE): The above-mentioned exposed conductive parts, main earthing terminal board, grounding and power ground (or artificial ground) electrically connected to any part of the conductor . The exposed conductor for connecting a plurality of conductive parts called protection trunk. (5) Grounding: The main ground terminal board or the exposed conductive parts directly connected to a protective grounding wire. For connecting a plurality of ground terminals board ground lines called ground lines. (6) other potential connection: refers to the potential of each of the exposed conductive parts and devices is substantially equal to the outer conductive portions of the electrical connection GJX galvanized steel strand Anhui Electric Group _ quote _ galvanized steel strand by the Anhui Electric Group Shares Limited.
