11 kv outdoor vacuum circuit breaker

SanGao High Quality 11 kv outdoor vacuum circuit breaker are three phase AC 50Hz/60Hz outdoor high voltage switchgear. Mainly used for outdoor distribution systems of 10-35kV in rural and urban power grids. Combined with load current, overload current, and short circuit current, it can also be used in other similar places.

Structural characteristics

The 40.5KV Switch Recloser adopts a three phase column structure, which has the characteristics of stable and reliable breaking performance, no risk of combustion and explosion, maintenance free, small size, light weight, and long service life.

The three phase pillar and current transformer are made of outdoor epoxy resin solid insulation and wrapped with silicone gel; They are resistant to high temperature, low temperature, ultraviolet radiation, and aging.

Features:

1.The 40.5KV Switch Recloser can be stored, made, and broken through a motor, and can be operated through a handle.

2. The breaking short-circuit current can reach up to 25kA.

3. Micro motor spring mechanism (approximately 30W).

4. Installation method: Two installation methods are used.

5. Sealing performance: Reliable sealing technology is adopted.

6. Incoming and outgoing line methods: Ceramic sleeves are used to ensure sufficient insulation distance.

7. Safe operation: equipped with explosion-proof devices.
