1. High Insulation Safety: DMC/epoxy components isolate high-voltage circuits from operating mechanisms, meeting 12kV/24kV medium voltage insulation standards and preventing electric shock risks.
2. Flexible Conductive Connection: Tin-plated copper braid ensures low contact resistance, compensates for installation errors, and enhances current-carrying capacity.
3. Visual Safety Indication: Position indicator box clearly marks “working/earthing” status to avoid misoperation and improve maintenance safety.
4. Mechanical Durability: Standardized design ensures smooth switching action, with mechanical life ≥10,000 operations, suitable for long-term use in SF6 gas chambers.
5. Corrosion Resistance: All parts are compatible with SF6 gas environments, resisting corrosion and aging for reliable performance in harsh conditions.
1. Insulation Operating Links/Levers: DMC/epoxy material, used to transmit operating torque and isolate high voltage.
2. Tin-Plated Copper Braid Flexible Connection: Flexible conductive component for current transmission and installation error compensation.
3. Position Indicator Box: Displays “working/earthing” status to prevent misoperation.
4. Insulation Supports/Insulators: Provide mechanical support and electrical isolation for conductive circuits.
5. Mounting Brackets & Fasteners: Galvanized steel parts for stable assembly and installation of the entire kit.
