Our pole assemblies feature epoxy encapsulation for high-volume insulation, delivering dielectric strength over 50kV/mm and reliable performance unaffected by humidity. They withstand 250kV lightning impulses and 150kV switching surges even in salt spray environments. Designed for durability, the seismic-resistant structure limits displacement to under 0.1mm at 0.5g vibration, while the modular design cuts assembly time by 40%. Copper cooling frames keep temperature rise under 30K at 4000A load, and the SF6-free design reduces global warming potential by 99% compared to traditional GIS. With a 30% volume reduction for compact integration and maintenance intervals extended to 50,000 operations, these poles meet IEC and GB standards for modern high-performance switchgear.
