High standarded ZW8-12 outdoor vacuum circuit breaker

Overview:

ZW8-12 is a type of outdoor vacuum circuit breaker (VED), with 12KV, three-phase AC-50HZ electric system.The operating mechanism is used with circuit breaker one-piece spring mechanism, which can be operated in AC or DC and manual operation or electric operation .

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.
