ZW32-12 Outdoor Vacuum Circuit Breaker
The ZW32-12 is a pole-mounted outdoor vacuum circuit breaker rated at 12kV, widely used in rural and urban power distribution networks. Features a compact spring-operated mechanism for reliable switching operations.
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.
SPV-24 Outdoor Vacuum Circuit Breaker (24kV)
The SPV-24 is a 24kV oil-free, SF6-free, maintenance-free outdoor vacuum circuit breaker by NAIJI Electric. Extended voltage class with enhanced insulation levels (125/145kV lightning impulse withstand). Same proven longitudinal magnetic field rotating arc technology and solid epoxy resin insulation (APG vacuum casting) as the SPV-12. Every unit X-ray inspected. Weighs only 2/3 of comparable products. Ideal for 20kV distribution systems and higher voltage applications.
