Product Description

High standarded ZW32-12 outdoor vacuum circuit breaker

Overview:
ZW32-12 is a type of outdoor vacuum circuit breaker (VED), with 12KV, three-phase AC-50HZ electric system. All products conform to GB1984-2003,JB/T3855-2008,DL/T403-2000and IEC62271-100:2001 standard rule.

The feature:
1. The stable performance: First-class producing system and professional package ensure high quality and stability.
2. EC-C2-M2 high standard circuit breaker performance and no maintenance.
3. It has very lower heavy breakdown rate during the specified short-circuit current breaking times test.
4. Long lifetime: the mechanical lifetime is 10000 times. Each cycling operation is up to 4000times no maintenance.
5.Small volume, light weight: The structure design is reasonable and easy to fix in the tower.
6.High performance: It uses the scientific once conductive circuit and structure layout. The once conductive circuit outside of box is wrapped with antioxidant, uvioresistant, temperature resistant ,freezing wind and frost resistant special silicone rubber, which has high intensity and tenacity. The once conductive circuit inside of box uses hung upside-down structure, which structure make sure both good electrical performance and good insulating and waterproof performance.
7. Original BaoGuang vacuum bubble and have high quality guarantee.

The operating environmental conditions:
1.Altitude: not more than 2000m, the plateau is not higher than 4000m.
2.Environment: -30 °C ~40 °C, -50 °C low temperature type circuit breaker limit.
3.Relative humidity: daily average value not more than 2.2kpa, on average less than 1.8 kpa.
4.Earthquake intensity: less than 8.
5.Can according to user requirements increase electric anti jump.
6.Wind: ≤ 700Pa (equivalent to the wind speed 34m/s)
7.Air pollution level: common grade III, special grade.
8.Available in more than GB/T11022-1999 specified above normal environmentalconditions, the user can be resolved in consultation with the manufacturer.
