Product Features

1. The primary components adopt a fully sealed design, completely enclosed within a sealed gas tank welded from stainless steel plates, filled with 0.04MPa SF₆gas as the insulating medium, achieving a protection rating of IP67. This fully shields the switchgear from external environmental and climatic influences, enabling reliable operation in harsh environments such as basements, plateaus, permafrost, coastal areas, humid regions, and deserts, with maintenance-free performance.

Features a modular design with fully insulated and shielded busbars and cross or T-shaped connectors, facilitating easy installation and flexible expansion. No gas filling is required during on-site cabinet assembly, and the gas leakage rate is extremely low.

2. Supports both manual and electric operation, with a mature and reliable operating mechanism, equipped with comprehensive mechanical and electrical interlocking to effectively prevent personal injury and equipment damage due to misoperation.
3. Compact design structure significantly reduces the volume compared to traditional air-insulated switchgear, with a footprint reduction of 30% to 70%, improving space utilization and effectively lowering overall project costs.
4. Specially designed to allow insulation testing of cables without opening the lower door of the ring main unit, meeting diverse customer needs. Based on microprocessor protection and system technology, it integrates protection, control, metering, monitoring, and communication functions, fulfilling comprehensive automation requirements and enabling fully unattended operation.
