Product Features: The materials used in the manufacture of the products are all non-toxic and harmless substances, without discharging any toxic or harmful substances. The materials can be recycled after the life cycle, which determines the environmentally friendly nature of the products. Fully insulated, fully sealed and fully shielded epoxy resin switch cylinder, fuse cylinder (epoxy resin has excellent electrical properties, mechanical properties, thermal properties, which has long been applied to electrical equipment, and achieved good results). The switch cylinder and fuse cylinder are formed through the epoxy resin APG process.The insulating cylinder is a key component for solid insulation switches, whichis both the insulating and the bearing parts. It requires that such technical requirements as heat resistance, weatherability, cracking resistance, high mechanical strength, and good insulation strength are all satisfied at the same time. Cylinders have large volume, a large number of inserts, diverse shapes, which are relatively difficult to make. Kaili Electric Appliances has many years of experience in the design and manufacture of insulation parts, to ensure high-quality mass production of the components in terms of cylinder design, material formulation, and process. In addition to the operating mechanism, the high-voltage switch part of solid insulation indoor AC high-voltage vacuum switchgear is in a fully sealed state, to save cleaning and maintenance, thus reducing the cost of operation and maintenance. The touchable part is designed with the shielding measure to prevent the occurrence of personal electric shock accidents and improve the safety of use. The perfect interlocking system, and the clearly visible three-phase isolated fracture can prevent the occurrence of misuse accidents. Completely abolishing the application of SF6 gas can prevent the SF6 ring main units from decreased insulation properties and arc-quenching capacity due to lack of gas pressure which thereby causes explosion. The strengthened phase separation structure can prevent inter-phase or multi-loop short circuits which may expand or cause an explosion. With the explosion-proof vacuum interrupter, the switch sleeve provides further protection for the switch. The auxiliarygrounding switch of load switch - fuse combination electric appliances adopts the vacuum switch tube fixed inside the fuse cylinder.
