1. JDX series high-voltage grounding wires are composed of line end clips, wire lugs (terminals/terminal lugs), collector clips (manifolds), grounding levers, short-circuit cables, grounding cables, grounding terminal clips or temporary grounding electrodes. 2. JDX series high-voltage grounding wire line end clamps and grounding end clamps are made of high-quality aluminum alloy die-casting, or copper line end clamps and grounding end clamps can be selected according to the actual situation, and the matching fasteners are all nickel-plated. 3. The JDX series high-voltage grounding wire grounding lever is made of high-grade epoxy resin and glass fiber with excellent electrical properties and mechanical strength. At the same time, a silicone rubber sheath is added to the operating handle, which is firm and insulated, and the insulation is safer and more reliable. 4. JDX series high-voltage grounding wire short-circuit cables and grounding cables are made of multi-strand copper stranded wires and covered with a soft, high-temperature-resistant transparent insulating sheath, which can prevent the wear of the grounding copper wire in use and ensure that the operator can Safety in operation. 5. JDX series high-voltage grounding wire lugs and bus clips are softly connected with grounding copper wires and outer sheaths by a new crimping process, and are covered with insulating heat-shrinkable sleeves, which can effectively prevent copper wires from breaking strands at the connection during use. Improve the reliability and service life of the ground wire. 6. The grounding wire is a temporary grounding device. Compared with the fixed grounding wire, it is more convenient to use, more flexible in the grounding point, and higher in safety and reliability. When the electrical equipment and power lines are outaged for maintenance and inspection, it can prevent sudden calls, The attack of the residual charge of the induced current ensures the life safety of the operators on the equipment.
(1) When connecting the grounding wire: connect the grounding clip first, and then connect the electric clip; when removing the grounding wire, the electric clip must be disassembled first, and then the grounding clip must be disassembled according to the procedure. (2) Installation: Fix the double-eye copper nose on the grounding soft copper wire on the phase-separated phase to the corresponding position of the power connection clip on the ground rod (the power-connection clip has a fixed and movable type), and connect the single-eye copper nose on the grounding wire. Fixed on ground clips or ground pins to form a complete set of ground wires. (3) Verify that the voltage level of the ground rod is consistent with the voltage level of the operating equipment. (4) Grounding soft copper wire has split-phase type and combined type, and grounding rod has flat-mouth type and double-reed hook type clip. Before using the portable short-circuit grounding wire, you should first check the power supply to confirm that the power has been cut off, and then confirm that there is no voltage on the equipment. First connect the grounding clamp to the grounding grid or flat iron piece, and then use the grounding rod to tighten the wire ends on the equipment wires respectively. When removing the shorted ground wire, the sequence is reversed from the above. The distance between the installed short-circuit grounding wire and the live equipment, taking into account the influence of the grounding wire pendulum, the safe distance should not be less than the value newly stipulated in the "Electrical Safety Work Regulations". It is strictly forbidden to use the method of winding to make a grounding short circuit without using a wire clip. If there is a grounding point at the suspension point, use a grounding clip or a special copper rod for grounding connection; if there is no fixed grounding point available, a temporary grounding point can be used, and the grounding electrode should be buried underground at a depth of not less than 0.6m. The portable short-circuit grounding wire should be kept properly. Before each use, it should be carefully checked whether it is in good condition, the soft copper wire is not exposed, and the nut is not loose, otherwise it should not be used. The inspection cycle of portable short-circuit grounding wire is once every five years, and the inspection items are the same as the factory inspection. The portable short-circuit grounding wire that has passed the test should be judged according to the magnitude of the short-circuit current and the appearance inspection after being short-circuited, and generally should be scrapped.
The selection of the high-voltage grounding wire is mainly determined according to the voltage level and the high-voltage grounding wire under the use environment. The specific configuration of the high-voltage grounding wire under different voltage levels and the use environment is completely different; Be sure to determine the exact operating voltage and specific operating environment, or the following details: operating voltage, the length of the grounding rod, the style of the connecting clip, the wire diameter of the grounding soft copper wire, the length of the short-circuit wire and the grounding wire, grounding method, etc.
