Product Overview

The ZW32 outdoor high-voltage vacuum circuit breaker is a mainstream outdoor switchgear for 10kV distribution systems. It adopts vacuum arc extinguishing technology and a fully sealed structure, primarily used for making and breaking load currents, overload and short-circuit fault protection in overhead lines, distribution zones, industrial and mining enterprises, and new energy distribution systems. With stable performance and reliable operation, it supports frequent switching, effectively ensuring safe and stable power supply. It is a core preferred device for urban and rural network upgrades and outdoor distribution projects.

The product features an outdoor anti-corrosion design, excellent insulation performance, and strong weather resistance. It strictly adheres to power industry standards, offering high breaking capacity, long mechanical life, maintenance-free operation, and high cost-effectiveness. It adapts to various complex outdoor conditions and is widely used in municipal distribution, industrial parks, rural power grids, and PV/wind power distribution scenarios.
 

Operating Environment

1.   Ambient temperature: -40℃ to +55℃, withstands extreme outdoor temperatures and temperature variations.

2.   Altitude: ≤1000m (reinforced insulation available for high-altitude areas).

3.   Relative humidity: ≤95% (at 25℃), fully sealed against moisture and condensation, preventing internal insulation breakdown.

4.   Installation site: Outdoor overhead lines, distribution zones, substations, industrial plants. No highly corrosive gases or explosive dust.

5.   Protection level: IP65, fully sealed against dust, water, pollution, and corrosion, resisting rain, sand, sun exposure.

6.   Installation requirements: Pole-mounted or ground-mounted with reliable grounding, safe insulation clearances, no violent vibration or impact.
