Product Description

Product Description
ZW32-40.5 model Outdoor high-voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is outdoor distribution equipment with rated voltage 35kV, 3 phase AC 50Hz. It is mainly used for breaking and making the load current and short-circuit current in power system, is applicable to the distribution system of substations and industrial & mining enterprises for protection and control, Rural power grid, and is further applicable to the sites with frequent power operation.
The installation instructions provided the main technical parameters and product structure of the circuit breaker, as well as operation, installation, use and maintenance of the principles and methods.

Model Description

Product technical parameters and external dimensions

Product structure features

1.Vacuum circuit breaker can greatly improve the reliability of overhead distribution networks by mitigating the impact of momentary faults.
2.Vacuum circuit breaker reduce outages from these transient sources, increasing uptime of power supply.
3.Utilities that deploy reclosers for their overhead distribution networks experience significant reliability improvements.
4.Longer product service life and more resilience to bad weather.

Product model selection

Environment condition

1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h.
2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M.
3. Relative humidity should not exceed 50% at max temperature +40. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20. But in view of the temperature change, it is possible that moderate dews will produce casually.
4. Installation gradient not exceed 5.
5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components.
6. Any specific requirement, consult with manufactory.
