Product Description

Product details:
Description:
Type ZW7-36 outdoor high-voltage vacuum circuit breaker is a kind of outdoor high-voltage switchgear under three-phase AC 50Hz, 36kv rated voltage and below. It can be used to switch on and off the loading, overloading and short-circuit current.
Features:
1. Storage, making and breaking by motor, It can operating by handle.
2. Breaking short-circuit current up to 25kA.
3. Mini motor spring mechanism (about 30W).
4. Installation method: adopt two type installation method.
5. Sealing performance: adopt reliable sealing technical.
6. Incoming & Outgoing method: adopt silicon bushing to make enough insulate distance.
7. Safe operating: there is an equipment to protect explosion.
