1. Overview
The () series of portable short-circuit grounding wires are used in accordance with the technical standards of the Department of Energy for short-circuit grounding on the equipment and lines to be repaired, in order to discharge residual charges. , to prevent dangerous voltages and arcs during incoming calls or induced voltages caused by the influence of nearby live equipment and lines, and to prevent workers from being electrocuted or severely burned. Therefore, the number of short-circuit grounding wires to be hung should be correctly selected according to the safe work accumulation, and the hanging location should be correctly selected. . Use the short-circuit grounding wire correctly. After taking these measures, you can avoid the effects of dangerous voltage and arc
2. Structural features
. It consists of wire end clamps, short-circuit wires, bus clamps, grounding wires, wiring lugs, It consists of a grounding terminal clamp or a temporary grounding electrode and a grounding operating rod.
. The wire clamps at the wire end and grounding end are made of high-quality aluminum alloy die-casting, and the supporting fastener metals are all nickel-plated.
3. The grounding operating rod is made of high-grade epoxy resin and glass fiber with excellent insulation performance and mechanical strength. At the same time, the operating handle is equipped with a silicone rubber sheath, which makes the connection firm and the insulation safer and more reliable.
.The short-circuit line and the grounding wire are made of multiple strands of high-quality soft copper wires, and are covered with a soft, high-temperature-resistant transparent insulating sheath, which can prevent wear and tear on the grounding copper wire during use and ensure that operators can Safety in operation.
.The wiring lug, bus clip, grounding copper wire and outer sheath adopt a new crimping process. The soft connection can effectively prevent the copper wire from being broken during use, improving the reliability and service life of the grounding wire.
3. Precautions for the use of grounding wires:
Electrical industry operators should operate according to the procedures stipulated in the "Safety Work Regulations" of the electrical industry. First connect the grounding wire clamp, and then connect the short-circuit clamp when removing the grounding wire. , the short-circuit clamp must be removed first according to the procedure, and then the grounding terminal clamp must be removed. Strictly follow the procedures stipulated in the "Safety Work Procedures" of the electrical industry to operate the ground wire to ensure personal safety.
4. Maintenance and Storage
Before each use, carefully check whether the grounding wire is intact. The soft plastic copper wire should not be exposed or broken, and the nut should not be loose. Otherwise it shall not be used. The product should be kept neat and clean, and should not be dropped anywhere. Pay attention to cleaning and hygiene work to prevent sediment and dirt from entering the pores of the product, thereby affecting the normal use of the ground wire. The ground wire after experiencing short-circuit current should be based on the size of the short-circuit current it has experienced. Judging from the appearance inspection, it should generally be scrapped.
