Power distribution equipment is an important part of the distribution network, including circuit breakers, high-voltage power distribution cabinets, transformers, power lines, lightning arresters, low-voltage switchgear, switchboards, switch boxes, control boxes and other equipment, some of which are installed in On outdoor towers, including on-pole power distribution equipment, vacuum switches, etc., the power distribution equipment in operation should carry out regular preventive tests in order to timely discover equipment hidden dangers and prevent accidents or equipment damage. The pole has a certain height from the ground, and it cannot be directly tested on the ground like ground equipment. Usually, the method of pole-mounted wiring test is adopted, and the insulating operating pole is fixed on a firm component such as the transformer shell or cross-arm by binding. Then lead the test copper wire down to the ground test transformer through the metal end of the insulating operating rod.
