New Energy Integrated Transformer

Neel Electric’s compact 40kV oil-immersed transformer for solar and wind farms delivers up to 4000kVA capacity, extreme‑weather reliability (‑40°C to +50°C, 3000m altitude), and space‑saving integration – the ideal renewable energy distribution substation for large‑scale projects.

Product Introduction

Engineered to meet the surging demand for both photovoltaic and wind power generation, our Renewable Energy Combination Transformer series seamlessly integrates domestic and international technologies. This advanced compact substation, designed for solar and wind power plants, combines the transformer, load break switch, and high-voltage fuses into a single, space-saving oil-filled tank. Utilizing premium transformer oil for superior insulation and cooling, it ensures reliable power distribution and grid integration even in the most demanding and variable environmental conditions.

 

Features

· Robust Environmental Adaptability:  Designed to withstand extreme conditions with an operating altitude of up to 3000m and a wide ambient temperature range of -40°C to +50°C.

· Superior Reliability:  Built to resist high humidity (Daily avg ≤95%) and seismic activity (Horizontal acceleration 0.4m/s²), ensuring stable operation in complex terrains.

· High-Capacity Performance:  Available in capacities from 680 to 4000 kVA for systems up to 40kV, making it an ideal 40kV oil-immersed transformer for large-scale solar farms.

· Safety First:  Installation sites require no special vibration damping and are protected against corrosive or flammable gases, ensuring long-term safety and low maintenance.
