ZWAT□ 12 outdoor ac high voltage special safety vacuum circuit breaker product details:

ZWAT□-12 outdoor ac safety special high voltage vacuum circuit breaker is an outdoor high voltage switchgear with rated voltage of 12kV and three-phase ac of 50HZ.
It is mainly used for load current, overload current and short circuit current of power system.
 

It is suitable for protection and control of substation, industrial and mining enterprises, urban and rural networks, especially for the distribution network system in which the overhead line is replaced by the cable line into the ground.
 

Features: 1. Shielded EMPD rubber encapsulates, insulates and shields the internal high-voltage components (vacuum arcing chamber and conductive circuit).
EPDM rubber is specially treated and treated with anti-oxidation to ensure long-term safety.
 
2. Vacuum arc extinguishing chamber
A miniaturized vacuum arcing chamber is equipped with high performance, high parameters and low resistance of the main circuit.
 
3. Insulated tie rod
It connects the spring operating mechanism with the contact of the vacuum arcing chamber. This design contains a unique high dielectric performance. In order to ensure reliable insulation voltage performance, a soft silicone rubber seal is used instead of the traditional SMC insulation tie rod form.
 
4. Compact structure and light weight
Taking advantage of the high insulation strength of epdm over SF6, oil or air, this product is remarkably small in size and light in weight.
Can be installed in the crowded cable trench and the smallest wall, installation can be through the doorway and artificial skylight.
The MVI segment can be installed in any location.
Floor, ceiling and walls.
Ensure the best connection and operation.
 
5. Spring structure
High reliability, miniaturized spring operating mechanism, mechanical life up to 20,000 times
6. Switch enclosure
Stainless steel casing and molded sealing groove ensure corrosion resistance and sealing.
 
7. Full seal and diving
Pollution, corrosion or continuous flooding will not affect the switch.
Stainless steel exterior and EP rubber ensure that the vacuum arcing chamber is not affected.
 
8. Maintenance-free design
Adopt EP rubber solid insulation to solve oil level, gas pressure or shell maintenance.
The vacuum arcing chamber is proved to be maintenance-free by cyclic test.
 
9. Wide application
This product can be used under the harsh operating environment such as underwater (water depth 2m, within 72 hours), severe pollution, moisture, etc., and can also be installed
