SISELA Series Solid Insulated Ring Main Unit

The SISELA series solid insulated switchgear adopts solid encapsulation insulation technology and vacuum arc extinguishing technology to achieve insulation and arc extinguishing. All high-voltage components inside this type of switchgear, such as switches, busbars, bushings, and connecting conductors, are fully sealed with solid insulation. Due to the use of solid insulation medium, the switchgear is compact in size. The fully sealed and fully insulated design ensures that the equipment is unaffected by factors such as altitude, temperature, condensation, and pollution. At the same time, it effectively addresses environmental pollution and greenhouse effect issues caused by SF₆ gas-insulated products. Therefore, the solid insulated ring main switchgear (SIS) combines the advantages of air-insulated switchgear, such as environmental friendliness, easy combination, and flexible expansion, with the benefits of gas-insulated cabinets, including small size, full protection, and strong environmental adaptability, offering higher reliability.
