Xizi Energy’s alloy protective covers are engineered for 12kV/24kV SF6 ring main unit (RMU) earthing switches. Made from high-strength die-cast aluminum alloy, they offer robust mechanical protection, corrosion resistance, and precise alignment with switch mechanisms. Compliant with IEC 60282, they ensure reliable performance in global medium-voltage power distribution networks.
1. Mechanical & Electrical Protection: High-strength aluminum alloy construction shields earthing switch components from impact, dust, and accidental contact, while maintaining insulation coordination in SF6 gas chambers.
2. Corrosion & Wear Resistance: Precision die-cast alloy with anti-corrosion treatment withstands SF6 gas corrosion, temperature fluctuations, and long-term mechanical wear for extended service life.
3. Precise Fit & Guidance: Customized hexagonal bore and slot design ensures accurate alignment with the earthing switch operating mechanism, enabling smooth, reliable switching operations.
4. SF6 Gas Compatibility: Seamless structural design integrates with the RMU gas compartment, preserving gas-tight integrity and avoiding SF6 leakage risks.
5. Easy Installation: Standardized dimensions fit mainstream 12kV/24kV SF6 ring main units and inflatable cabinets, simplifying assembly and retrofitting.
