1. Superior Electrical Insulation: Molded from high-temperature cured epoxy resin, it reliably isolates live cable terminals/contact fingers from grounded metal frames, meeting strict creepage distance requirements for SF6 gas-insulated switchgear.
2. Arc & Weather Resistance: Smooth, hydrophobic surface withstands short-circuit arcs, SF6 gas corrosion, and extreme temperatures (-40°C~+85°C), ensuring long-term durability.
3. Gas-Tight Compatibility: Precision structural design integrates seamlessly with SF6 RMU gas compartments, eliminating leakage risks and preserving insulation integrity.
4. Precise Fit: Unique hemispherical + dual-wing structure ensures stable installation with cable terminals, earthing switches, or fuse components in SF6 inflatable cabinets.
5. Safety Enhancement: Acts as a physical barrier to prevent accidental contact with live parts, boosting operational safety.
