Insulating bar consists of three parts: work head, insulation rod and handle. It is used for closing or pulling high voltage isolation switches, mounting and dismounting portable ground cables, and for measuring and testing.
Insulating rods can be divided into two types according to the combination, one is an interface type insulating rod and the other is a telescopic type insulating rod. The interface type is relatively durable, and the telescopic type is relatively easy to operate. According to the use of the environment can be divided into two types: one is a normal pull-bar, the other is a rain-proof pull-bar. According to the material is divided into: glass Brass brake lever, phenolic resin brake lever, epoxy pull brake lever and so on.
Insulating rods are tested once a year. 6 to 10 kV plus 44 kV; 35 to 154 kV plus four times the phase voltage; 220 kV plus three times the phase voltage; test time is 5 minutes.
After the use of insulating rods, the stains on the surface of the rod body should be wiped clean in time, and the sections should be decomposed into a special tool bag and stored in a well-ventilated, clean and dry bracket or hanging. Try not to close to the wall. To prevent moisture and damage its insulation
Insulating bars are insulating tools used to operate live equipment for a short period of time, such as turning on or off high-voltage disconnectors, drop fuses, and so on. Insulating rods are one of the most commonly used safety tools for grass-roots rural power workers. They are mainly used to stop power transmission to rural distribution transformers and line switches. They are directly in contact with high-voltage electrified bodies. Therefore, it is necessary to properly master the insulation levers. Use requirements and precautions.
1. An ac voltage withstand test must be conducted every year. Unqualified insulation rods shall be scrapped and destroyed immediately. They shall not be reduced in standard use, and shall not be put together with qualified insulation rods.
2. Select a well-ventilated, clean and dry place when storing, and hang the square on the special gate bar, and manage it by someone else. The insulation plate should not be in contact with the wall to prevent it from getting wet.
3. Once the surface of the insulating rod is damaged or wet, it should be treated and dried in time. Damage to the surface of the shaft should not be tangled with ribbons such as wire or plastic tape. When drying, it is best to use the natural drying method of sunlight. After handling and drying, the gate must be tested before it can be reused.
4, an insulating rod generally consists of three sections. When storing or carrying, the sections should be disassembled and then the exposed threads should be put into special special tool bags with their ends facing upwards to prevent scratches on the surface of the shaft or damage to the threads.
