ZWAT□-12 Type Outdoor AC High Voltage Special Safety Vacuum Circuit BreakerDetailed product description：

ZWAT □ -12 outdoor AC safety special high-voltage vacuum circuit breaker is an outdoor high-voltage switchgear with a rated voltage of 12kV and three-phase AC 50HZ. Mainly used for breaking and closing load current, overload current, and short-circuit current in power systems.

Suitable for protection and control in substations, industrial and mining enterprises, as well as urban and rural power grids, especially suitable for distribution network systems where urban overhead lines are converted to cable lines that enter the ground.

Product features: 1 The shielded EMPD rubber encapsulates, isolates, and shields the internal high-voltage components (vacuum arc extinguishing chamber, conductive circuit). EPDM rubber is specially treated and undergoes antioxidant treatment to ensure long-term safety performance.
2. Vacuum arc extinguishing chamber
Adopting a miniaturized vacuum arc extinguishing chamber equipped with high performance, high parameters, and low main circuit resistance value.
3. Insulation rod
It connects the spring operating mechanism and the vacuum arc extinguishing chamber contact, and this design includes 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 rod form.
4. Compact structure and light weight
Taking advantage of the higher insulation strength of EPDM rubber compared to SF6, oil, or air, this product has eye-catching features of small size and light weight. It can be installed in crowded cable trenches and within the smallest walls, and can be installed through doorways and artificial skylights. The MVI segmenter can be installed at any position. For example, floors, ceilings, and walls. Ensure the best connection and operation.
5. Spring structure
High reliability, miniaturized spring operating mechanism, with a mechanical lifespan of up to 20000 cycles
6. Switch casing
Adopting stainless steel shell and formed sealing groove to ensure rust resistance and sealing.
7. Fully sealed and submersible
Pollution, rust, or continuous flooding will not affect the switch. The stainless steel exterior and EP rubber ensure that the vacuum arc extinguishing chamber is not affected.
8. Maintenance free design
Adopting EP rubber solid insulation solves the maintenance of oil level, gas pressure or shell. The vacuum arc extinguishing chamber has been confirmed to be maintenance free through cyclic testing.
9. Widely applicable
This product can be used in harsh operating environments such as underwater (water depth of 2m, within 72 hours), severe pollution, and humidity, and can also be installed
