Xizi Energy’s epoxy resin post insulators are engineered exclusively for 12kV/24kV SF6 ring main unit earthing switches. Crafted from high-temperature cured epoxy resin with a multi-shed design, they deliver superior electrical insulation, high mechanical strength, and arc resistance. Compliant with IEC 60282, these insulators ensure reliable isolation and support for medium-voltage switchgear in global power distribution networks.
1. Superior Electrical Insulation: Cast from high-temperature cured epoxy resin, these insulators provide reliable high-voltage isolation between live parts and the earthed frame, meeting strict creepage distance and dielectric strength requirements for SF6 ring main units.
2. High Mechanical Strength: The multi-shed design delivers excellent bending and impact resistance, withstanding mechanical stresses from earthing switch operations and short-circuit electromagnetic forces.
3. Arc & Weather Resistance: Smooth, hydrophobic surface resists SF6 arc impact, temperature fluctuations, and chemical corrosion, ensuring long-term performance in indoor/outdoor harsh environments.
Precise Compatibility: Standardized dimensions perfectly match the earthing switch’s moving/static contacts and operating mechanism, enabling reliable three-phase mechanical linkage and interlocking.
IEC Compliance: Manufactured to IEC 60282 and GB 3906 standards, ensuring compatibility with global medium-voltage switchgear systems.
