The ZGS new energy combined transformer is an all-in-one power distribution assembly that integrates power receiving, power feeding, and core transformer components into a single compact unit. This fully sealed solution houses the transformer body, high-voltage load switch, and protective fuses inside a unified oil tank, paired with a complete set of monitoring components including oil temperature gauge, oil level gauge, pressure gauge, pressure relief valve, and oil drain valve for real-time operational status tracking. With a capacity range of 50-5500kVA and a voltage rating up to 40.5kV, this transformer complies with the latest national energy efficiency standards, delivering ultra-low loss and exceptional energy-saving performance for renewable energy applications.
Unlike split-type power distribution systems, the ZGS wind solar combined transformer integrates all critical power components into one sealed enclosure, reducing floor space by up to 60% and simplifying on-site installation for fast project deployment.
Engineered to meet the latest mandatory energy efficiency regulations, this unit minimizes no-load and load losses, cutting long-term operational energy costs and ensuring full compliance with grid connection requirements for renewable energy projects.
The built-in multi-parameter monitoring system and full set of safety protection devices deliver 24/7 real-time oversight, mitigating operational risks and reducing unplanned downtime for remote renewable energy installations.
The fully sealed oil tank design isolates internal components from moisture, dust, and corrosive elements, ensuring stable operation in extreme onshore and offshore environmental conditions.
