ZW32-24 Outdoor Vacuum Circuit Breaker (24kV)
The ZW32-24 is a 24kV outdoor vacuum circuit breaker with spring operating mechanism, rated at 630A with short-circuit breaking capacity up to 25kA. Widely used in hydropower stations, industrial substations, renewable energy grid connections, and rural/urban distribution networks. Control voltage options include 110VDC, 220VDC, and 220VAC. Fully compliant with IEC 62271-100.

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.
