1. Superior Electrical Insulation: Molded from high-temperature cured epoxy resin, it provides reliable high-voltage isolation between live contacts and earthed metal frames, meeting strict creepage distance requirements for SF6 gas-insulated switchgear.
2. Arc & Corrosion Resistance: Smooth, dense surface withstands short-circuit arc impacts and SF6 gas corrosion, ensuring long-term durability in harsh operating environments.
3. SF6 Gas-Tight Design: Precision-machined structure integrates with the RMU gas compartment, preventing SF6 leakage and maintaining the integrity of the gas insulation system.
4. Standardized Compatibility: Universal dimensions fit 12kV/24kV SF6 ring main units and inflatable cabinets, enabling easy installation and retrofitting with mainstream switchgear models.
5. Physical & Electrical Protection: Acts as a protective cover to prevent accidental contact with live parts, while enhancing insulation performance for safe operation.
