Today, the ZN85-40.5 indoor high-voltage vacuum circuit breaker series, developed and manufactured by Shaanxi West Power Tongzhong Electric Co., Ltd., a renowned domestic electrical equipment producer, has formally entered the shipping preparation phase following the successful completion of all factory tests and quality certifications.
Main technical parameteres
Rated Voltage: 40.5kV
Operating Mechanism: Modular operating mechanism.
Installation Method: Floor handcart type.
Product Advantages: E2-C2-M2 performance, convenient maintenance, high conductivity performance, wide range of applications.
Outstanding features
Exceptional breaking performance: Utilising advanced vacuum arc extinguishing chambers and optimised contact systems, it rapidly and reliably interrupts both load and fault currents, minimising impact on the power grid.
Environmental Protection and Safety: Utilising vacuum as both the insulating and arc-quenching medium, these units are oil-free and emit no sulphur hexafluoride (SF6), aligning with green grid development principles. Furthermore, the fully enclosed pole design effectively shields against external environmental influences, ensuring high safety standards.
In the production workshop, journalists observed technicians conducting final packaging inspections on circuit breakers ready for dispatch. Each unit undergoes rigorous factory testing, including mechanical characteristic tests, main circuit resistance measurements, power frequency withstand voltage tests, and lightning impulse tests, ensuring its performance parameters fully comply with or even exceed both national standards and International Electrotechnical Commission (IEC) standards.
