1. Insulating Operating Rod Composition Working part: Plays the role of the completion of the operating function, mostly made of metal materials, the style is different due to different functions, are installed on the insulating part above. Insulation: It plays a role in insulation and isolation. It is generally made of insulating materials such as bakelite, bakelite, plastic tape, and epoxy glass cloth. Handshake section: Made of the same material as the insulation section.
2. The requirement for insulated operating rods is to ensure that there is a sufficient insulation safety distance during operation, the length of the insulating part of the insulated operating rod must not be less than 0.7 meters; the material must have high compressive strength, corrosion resistance, moisture resistance, mechanical strength, and light weight , Easy to carry; the connection between the three sections should be solid and reliable, and must not fall off during operation.
3. Precautions for use The appearance of the insulation operating rod must be checked before use. The external appearance must not be cracked, scratched, or other external damage. It must pass the calibration; it must be applied to the voltage level of the operating equipment, and it can be used only after it has been checked; In rain and snow weather, when operating outdoors, special insulated operating rods with rain-proof snow cover are used; when connecting the joints of insulated operating rods and the threaded parts of the joints, they must leave the ground to prevent weeds and soil from entering the threads or Stick on the surface of the rod body, the thread should be tightened; when using it, the bending force on the rod body should be minimized to prevent damage to the rod body; the stains on the surface of the rod body should be wiped off in time after use, and the sections should be decomposed into a Store in a special tool bag on a well-ventilated, clean and dry rack or hang it. Try not to approach the wall as much as possible to prevent moisture and destroy its insulation. Insulating operating rod should be kept by special person; Conduct an AC voltage withstand test. Disqualify immediately and scrap it. Do not reduce the standard use.

Insulation operating lever use and precautions
Use insulated operating rod and precautions <br> <br> insulated operating rod is one of the most commonly used security tools grass-roots rural power staff, mainly used in rural distribution transformers and circuit switch electrical cut-off operation, because Direct contact with the high-voltage electrified body, so it is necessary to correctly grasp the use of insulation operating lever and precautions.
