With performance indices conforming to SD332-89, our XJ series portable short-circuit grounding wire is qualified by the Quality Surveillance Inspection Center for Electrical Safety Tools and Apparatuses of Electric Power Industry and approved to be used for power grid. This product mainly consists of wire hook/clamp or flat busbar clamp, short-circuit jumper grounding tail, connection lug, bus tube, grounding terminal clamp, steel grounding rod and operating rod. With polished casting surface, the wire clamp made of quality aluminum alloy is fastened to the connection lug; the conductor is an important part of portable short-circuit grounding wire. Our short-circuit wire and grounding rod is superior to similar French products and may provide reliable safety guarantee for power-off maintenance of high/low-voltage electrical lines and equipments. The operating rod is made with imported glass fiber reinforced epoxy resin tube with high mechanical strength and insulation performance as per type demand. DLJ series portable short-circuit grounding wire has two types, namely split-phase type and combined type, and is divided into the following by operating voltage: 500VDLJ portable short-circuit grounding wire, 10kVDLJ portable short-circuit grounding wire, 35kVDLJ portable short-circuit grounding wire, 110kVDLJ portable short-circuit grounding wire, 220kVDLJ portable short-circuit grounding wire and 500kVDLJ portable short-circuit grounding wire. The wires may be used for power plant, power supply, telecommunication, railway, subway and other substation users and construction organizations, and can be customized as requested.
