SPV-12 Outdoor Vacuum Circuit Breaker (12kV)
The SPV-12 is a 12kV oil-free, SF6-free, maintenance-free outdoor vacuum circuit breaker pioneered by NAIJI Electric. Features three-phase pillar-type structure with longitudinal magnetic field vacuum arc extinguishing technology and solid epoxy resin insulation (APG vacuum casting). The spiral groove contacts produce a rotating magnetic field, accelerating ionized particle diffusion and reducing arc energy. Special alloy shielding rapidly absorbs arc energy for low heat, short extinguishing time, and long service life. Imported outdoor-grade epoxy resin with integral vacuum casting — proven by 20+ years of outdoor operation with no surface carbonization. Every unit X-ray inspected. Weighs only 2/3 of comparable products.
