◎ Structural features

◇The internal configuration is highly reliable, economical and applicable. The high-voltage side is equipped with a load switch + fuse, which can reliably protect the transformer. The low-voltage side is equipped with an imported SOCOMEC isolation switch and a high breaking capacity fuse. At the same time, a 2KVA station transformer can be installed; the main circuit scheme is simple and economical; (high voltage The load switch and high-voltage fuse are placed in a fully sealed transformer oil tank, using transformer oil as the insulating medium. The high-voltage outlet end adopts a fully insulated silicone rubber cable joint, which is truly full working condition, fully insulated, fully sealed, and maintenance-free, ensuring that it can be used in harsh environments. The total service life in the environment is 20 years. ◇ Use imported high-ignition point oil as the insulation and cooling medium. No oil filtering or oil replacement is required during the service life. The seals use high-performance imported rubber beads, which have the same lifespan as the equipment. The door adopts a unique labyrinth sealing method and is equipped with highly elastic and long-life sealing strips. The ventilation holes are equipped with dust-proof facilities, which can effectively prevent wind erosion caused by sand, rain, snow, etc., and the protection level is IP44.
