III. Explanation:
[Product Name] On-Column Vacuum Circuit Breaker
ZW32-12
Outdoor High Voltage Vacuum Circuit Breaker
ZW32-12 series of outdoor high-voltage vacuum circuit breakers are outdoor high-voltage switchgear with three-phase AC 50Hz and rated voltage 12KV.
It is suitable for switching off and closing the load current, overload current and short circuit current of urban or rural distribution system.
The circuit breaker is a new miniaturized design, fully enclosed structure, unique arc extinguishing chamber packaging technology, good sealing performance, moisture-proof, anti-condensation, suitable for high temperature and humid areas.
ZW32-12G circuit breaker disconnector combination is composed of two parts: ZW32 circuit breaker disconnector.

IV. Use of environmental conditions:
1. The altitude does not exceed 2000 meters.
2. Ambient air temperature: - 45 +65 Daily temperature difference: 25 daily variation;
3. The wind speed is not more than 35m/s.
4. Places free from flammability, baozha hazards, chemical corrosion and severe vibration.

V. Structural characteristics:
The circuit breaker is composed of three-phase support and mechanism box. Its structure is simple and clear. The three-phase support and current transformer are insulated by outdoor epoxy tree solid or silicone rubber. It has high and low temperature resistance.
It has the advantages of ultraviolet resistance and aging resistance, small spring operating mechanism, low energy consumption for opening and closing, spindle sliding mode for transmission output, no torsion loss and fewer splitting and closing transmission parts.
High reliability; Current transformer installed in the moving end of the outlet, the second use of plug-in structure, easy maintenance and replacement.
