Long-Term Client Case Studies

Case Study 1: New Energy Sector — Photovoltaic Power Station. Located in the arid desert region of Northwest China, this power station faces extreme diurnal temperature fluctuations and frequent sandstorms, placing exceptionally high demands on the environmental adaptability of its electrical equipment. The project owner selected the XENHO 250A Mould Case Circuit Breaker to serve as the core protection device within the photovoltaic array combiner boxes. Its high-strength insulating housing effectively withstands erosion from sand and dust, while its precision tripping mechanism ensures accurate operation across a wide temperature range of -40°C to 70°C. After three years of operational validation, the product's failure rate remained below 0.3%, significantly reducing operation and maintenance costs and contributing to a 12% increase in the power station's annual electricity generation.

Case Study 2: Rail Transit Sector — Subway Power Supply System. During the renovation of a subway traction substation, XENHO products leveraged their modular design advantages to achieve seamless integration with existing equipment. Their intelligent monitoring interfaces were deeply integrated with the subway's comprehensive monitoring system, enabling the real-time transmission of critical parameters such as switching cycle counts and contact temperatures. By utilizing big data analytics to provide early warnings for potential faults, the system reduced unplanned equipment downtime by 65%, thereby safeguarding the transportation safety of a daily passenger volume exceeding one million.

Case Study 3: Industrial Automation Sector — Automobile Manufacturing Plant. The welding workshop at this facility was plagued by severe electromagnetic interference and metal dust contamination, causing traditional circuit breakers to frequently trip erroneously. XENHO products feature a specialized sealed structure and anti-interference algorithms, maintaining a 99.9% operational reliability rate even in such harsh environments. Furthermore, by utilizing customized tripping curves precisely tailored to match the inrush current characteristics of the welding equipment, the system eliminated nuisance tripping and boosted the overall efficiency of the production line by 18%.
