Applications of Wan Long Electric Low Voltage Equipment

Wan Long Electric's intelligent low voltage electrical equipment is trusted in a wide range of industries and applications worldwide. From heavy industrial plants to critical healthcare facilities, our switchgear, circuit breakers, transfer switches, and motor protection relays deliver reliable performance in the most demanding environments.

Industrial Manufacturing Plants

Industrial facilities require robust and intelligent power distribution systems to ensure continuous production. Our Intelligent Low Voltage Switchgear (MNS/GCS/GGD) and Air Circuit Breakers (ACB) are widely used as main incoming and distribution panels in factories producing steel, chemicals, textiles, food and beverage, automotive parts, and more. Our Motor Protection Relays protect critical production motors from overload, phase loss, and locked rotor faults, minimizing costly downtime.

Power Generation & Utility Substations

Our switchgear and ACBs are used in the secondary distribution of power generation plants, including thermal, hydro, wind, and solar power stations. They serve as main incoming breakers, bus-coupler breakers, and feeder breakers in utility substations, ensuring reliable power delivery to the grid and end users.

Data Centers & IT Facilities

Data centers demand the highest levels of power reliability and uptime. Our Automatic Transfer Switches (ATS) provide seamless changeover between utility power and generator backup in under 100ms, protecting servers and IT infrastructure from power interruptions. Our ACBs and MCCBs provide precise overcurrent protection for PDUs and UPS systems.

Hospitals & Healthcare Facilities

In healthcare environments, power continuity is literally a matter of life and death. Wan Long Electric's PC-class ATS ensures uninterrupted power to critical medical equipment, operating theaters, ICUs, and life support systems. Our products meet the stringent reliability requirements of healthcare power systems.

Commercial Buildings & Real Estate

Our MCCBs and switchgear panels are widely used in the main distribution boards (MDB) and sub-distribution boards (SDB) of office towers, shopping malls, hotels, and residential complexes. They provide reliable overcurrent protection and intelligent energy monitoring for building management systems (BMS).

Water Treatment & Pumping Stations

Water infrastructure relies on continuous motor operation. Our Motor Protection Relays and MCCBs protect pump motors from overload, phase failure, and dry-run conditions. Our ATS ensures backup power is available during utility outages to maintain water supply and treatment operations.

Oil & Gas & Petrochemical

The oil and gas industry demands electrical equipment that can withstand harsh environments and meet strict safety standards. Our switchgear and circuit breakers are used in onshore and offshore processing facilities, pipeline pumping stations, and LNG terminals, providing reliable power distribution and motor protection.

Mining & Tunneling

Mining operations depend on continuous, reliable power for conveyors, crushers, ventilation fans, hoists, and pumping systems. Wan Long Electric's Motor Protection Controllers (ST570 / ST570B1) provide real-time monitoring and protection for heavy-duty mining motors, preventing costly failures in underground and surface operations. Our MCCBs and switchgear are used in mine surface power distribution and DC traction power supply systems for mine transport.

Renewable Energy Systems

As solar and wind energy installations grow worldwide, reliable low voltage switchgear and protection devices are essential. Our products are used in the AC output distribution of solar inverters, wind turbine step-up transformers, and energy storage systems, ensuring safe and efficient power delivery to the grid.

Marine & Offshore

Our ACBs and MCCBs are suitable for marine power distribution applications, providing reliable circuit protection in ship main switchboards, generator panels, and distribution boards. Products can be supplied with marine-grade certifications upon request.

Telecommunications & Broadcasting

Telecom base stations, broadcast towers, and communication hubs require uninterrupted power. Our ATS and MCCBs ensure reliable power supply and protection for sensitive telecommunications equipment, with fast transfer times and intelligent monitoring capabilities.
