Designed for solar power plants and utility grid connection, this 0.69kV to 33kV oil immersed step-up transformer delivers stable voltage boosting performance for photovoltaic energy systems. It efficiently converts low-voltage output from solar inverters into medium-voltage power for long-distance transmission and grid integration.
The Solar Step-Up Transformer is specially designed for photovoltaic power generation systems and utility-scale solar farms. It converts the low-voltage output power generated by solar inverters (0.69kV) into medium-voltage power (33kV) for efficient long-distance transmission and stable grid connection.
This oil immersed power transformer adopts high-quality silicon steel cores and premium copper windings to ensure low loss, high efficiency, and long-term operational reliability. It is suitable for harsh outdoor environments and continuous operation in renewable energy projects.
Widely used in solar power stations, containerized substations, renewable energy systems, and utility grid integration projects.

Reliable Solar Power Transformation Solution
Efficient. Stable. Durable.
Customized transformer solutions for global photovoltaic power projects.
Yes, our MNS low-voltage switchgear is designed for universal compatibility with most standard low-voltage power distribution systems. Its modular configuration allows for easy integration with existing equipment, minimizing the need for extensive modifications and reducing installation costs.
The MNS switchgear is engineered for low-maintenance operation. We recommend routine visual inspections for dust accumulation and component integrity every 6-12 months. Major maintenance is rarely required under normal operating conditions, resulting in significant long-term cost savings.
While optimized for controlled indoor environments, the 304 stainless steel construction and flame-retardant materials enable reliable operation in moderately harsh conditions. For extreme environments with high humidity, dust, or corrosive elements, we offer additional protective enclosures and customized solutions.
Ready to upgrade your power distribution system with reliable, high-performance MNS withdrawable type power distribution switchgear? Contact our technical team today for a personalized consultation and free, no-obligation quote. We will work closely with you to design a solution that perfectly matches your facility’s power requirements and operational needs.
