High Voltage Outdoor Protection
The ZW7-40.5 Series Outdoor Vacuum Circuit Breaker is used in three-phase AC 50Hz power systems with a rated voltage of 40.5kV. It switches load current, overload current, and short-circuit current. This 40.5kV Outdoor Vacuum Circuit Breaker is an ideal choice for outdoor distribution at this voltage level.
We are ChangZhou HY Power Electric Co., Ltd. We started production on March 18, 2024. Our factory covers 1,400 square meters. We have 28 permanent employees. Our monthly capacity reaches over 200 vacuum breaker units. We have our own R&D team. We invest over 3% of our sales revenue into R&D each year. We are recognized as a Changzhou City Enterprise Technology Center and a member of the Jiangsu Electrical Apparatus Industry Association.
Strong Performance and Long Life
The 40.5kV Outdoor Vacuum Circuit Breaker uses a vacuum interrupter. It has strong breaking capacity and long electrical life. Mechanical life reaches 10,000 operations. The structure is simple. It is maintenance-free. The inspection interval is long. It has good insulation and high pollution resistance. You can choose spring or electromagnetic operating mechanisms. Mechanical performance is reliable. It supports frequent operations. There is no fire or explosion risk. Operation is safe.
Flexible CT Configuration
The built-in current transformer can achieve 0.2S class accuracy. This meets high-precision metering requirements. The 40.5kV Outdoor Vacuum Circuit Breaker can also implement three-phase differential protection. This gives better protection for transmission lines. The internal condensation controller keeps the breaker running reliably under certain temperature and humidity conditions. This extends the service life of the unit.
Quality and Certification
We strictly control quality. All purchased parts go through inspection. During production, every step has self-inspection and spot checks. Before shipping, each 40.5kV Outdoor Vacuum Circuit Breaker gets a full appearance check and power-on test. We accept third-party inspections. We offer a one-year warranty. Our export packaging uses three protective layers.
