Problems solved by technology

[0002] The solid-sealed pole shell in the existing insulating ring network cabinet is usually made of epoxy resin material. The epoxy resin material is brittle, and its insulation performance cannot be recovered after being damaged, which not only affects the use of the insulating ring network cabinet, but also may cause harm to the human body; in addition, in the production process, the cured epoxy resin is used as the raw material, and diluents, curing agents and accelerators will be added in the production process, so most epoxy resin coatings are solvent-based coatings. Contains a large amount of volatile organic compounds (VOC), which causes serious pollution and harm to the environment and human body during the production and use of epoxy resin materials, and the cost of epoxy resin is high. Column housings are difficult to recycle at end of life
