Case Study

Enhancing Solar Plant Safety in Spain

A leading Spanish solar energy contractor needed an air breaker switch solution to protect their 50MW photovoltaic installation. They required a device that could handle high DC voltages and frequent switching operations. ZHNYU ELECTRIC provided a customized air breaker switch with a breaking capacity of 1200V DC and a mechanical life of 15,000 cycles. The installation resulted in zero unplanned outages over two years, and the contractor reported a 25% reduction in maintenance costs. Their technical team praised the straightforward mounting and wiring, which reduced installation time by 40%.

Improving Continuity in a Chemical Plant

A chemical processing plant in Germany faced challenges with unexpected breaker trips due to corrosive atmospheres and high humidity. They deployed our air breaker switch, which features a corrosion-resistant coating and IP65 protection. Within six months, the plant achieved a 99.8% operational uptime, directly attributable to our switch's reliable insulation and arc extinguishing capabilities. The plant's maintenance team appreciated the visual indication of contact wear, which enabled proactive replacement and avoided downtime. Annual maintenance savings exceeded €50,000, and the switch operated flawlessly in temperatures up to 55°C.

Reliable Power Distribution in Urban Infrastructure

An infrastructure developer in the Middle East required air breaker switches for a commercial complex's low-voltage distribution. They chose our 630A model for its compact design and high breaking capacity, fitting seamlessly into their existing switchboards. Over a year of operation, the switches performed without a single fault, even during peak load periods. The developer highlighted the excellent thermal management, which kept operating temperatures 15°C lower than comparable units. Additionally, the air breaker switch's modular design allowed for easy upgrades, future-proofing the complex's electrical system. This partnership has since expanded to other projects, with the developer specifying our air breaker switches in over 20 new buildings.

Superior Arc Quenching Technology

Our air breaker switch employs a patented arc quenching technology that rapidly extinguishes electrical arcs, minimizing contact erosion and extending the switch's operational lifespan. This technology is particularly effective in high-inductance circuits found in industrial motors and transformers. In tests, our air breaker switch with this feature achieved a 30% longer electrical life compared to conventional designs. This innovation not only reduces maintenance interventions but also ensures operational safety and compliance with international safety standards. For industries such as metal processing and chemical plants, where arc flash risks are prevalent, this feature provides peace of mind, safeguarding personnel and equipment.

Modular Design for Easy Integration and Customization

The air breaker switch is designed with a modular approach, allowing for flexible integration into various switchgear configurations. This feature is especially valuable for clients who require scalable power distribution solutions. Our modular air breaker switch supports plug-in accessories, such as auxiliary contacts, shunt trips, and undervoltage releases, enabling customers to adapt the switch to evolving operational needs without replacing the entire unit. For example, a data center in Singapore upgraded their air breaker switch with remote monitoring capabilities by simply adding a communication module, reducing retrofit costs by 60%. The modular design also simplifies spare parts management, as components are interchangeable across models.
