Commercial and Civil Construct

Commercial Buildings

Commercial buildings (e.g., shopping malls, office towers, hotels, supermarkets, and business complexes) feature high electricity load, frequent load fluctuations, and strict requirements for power continuity—all of which rely on transformers to achieve reliable and efficient power distribution.

 

Residential Buildings

Residential buildings (e.g., high-rise communities, villas, and affordable housing complexes) prioritize power safety, low noise, energy conservation, and compatibility with daily living needs—transformers here are designed to align with residents’ quality of life and long-term living costs.

New Energy Field

Wind Power Generation

In wind farms (onshore or offshore), transformers primarily function to step up voltage—converting low-voltage power to medium/high voltage that meets long-distance transmission standards. This minimizes energy loss during delivery from remote wind farms to power grids. Additionally, they stabilize voltage fluctuations caused by variable wind speeds, ensuring the generated electricity matches grid frequency and voltage requirements, which is essential for safe and reliable grid connection.

Solar Power Generation

For solar power systems,  transformers play two key roles: voltage boosting and voltage adaptation. They also filter out minor current fluctuations caused by varying sunlight intensity, ensuring consistent power quality and reducing impacts on grid stability.

Industrial field

Manufacturing Industry

In manufacturing, transformers match the diverse voltage demands of production equipment—supplying low-voltage power for precision toolsand stabilizing high-voltage input for large-scale motors. They also reduce energy loss during power transmission, helping factories cut operational energy consumption while ensuring continuous, reliable power for 24/7 production, avoiding downtime caused by voltage fluctuations.

Mining Industry

Mining operations rely on transformers to adapt to harsh working environments (dust, humidity, extreme temperatures). Specially designed mining transformers supply high-power electricity for heavy equipment like crushers, hoists, and conveyor belts. They also isolate and protect the power system, preventing electrical faults from spreading and ensuring the safety of mining personnel and equipment.

Petrochemical Industry

Petrochemical plants (oil refining, chemical synthesis) require transformers with explosion-proof and high-temperature resistance features—critical for areas with flammable gases or volatile materials. Transformers here adjust voltage for process equipment and support the stable operation of auxiliary systems. Their high reliability ensures uninterrupted power for continuous petrochemical production, avoiding costly losses from unexpected shutdowns.
