Henan GNEE Electric Co., Ltd. is one of the most reliable manufacturers and suppliers of 750kva cast resin three phase dry type transformer in China. If you're going to buy customized 750kva cast resin three phase dry type transformer made in China, welcome to get quotation from our factory. Quality products and reasonable price are available.
The 750kVA cast resin Three Phase dry type transformer (often referred to as an SCB series transformer) uses epoxy resin to vacuum-cast the high and low-voltage windings. Unlike traditional oil-immersed transformers, this dry-type unit does not use flammable liquids, making it the safest choice for indoor environments.
Detailed view of GNEE's 750kVA cast resin transformer coils and core construction.
Key Structural Features ：
- Epoxy Resin Casting: The windings are encapsulated in high-quality epoxy resin under vacuum, preventing dust accumulation and moisture ingress.
- High-Grade Core: We utilize cold-rolled grain-oriented (CRGO) silicon steel sheets to minimize no-load losses and noise.
- Cooling System: Equipped with natural air cooling (AN) or forced air cooling (AF) to boost overload capacity by up to 40%.

Unmatched Advantages of Using a 750kVA Cast Resin Transformer
In modern urban and industrial settings, safety and environmental impact are top priorities. The 750kVA cast resin Three Phase dry type transformer excels in these areas, offering several distinct advantages over traditional alternatives.
Maximum Fire Safety and Environmental Protection
Because the transformer is "dry," there is zero risk of oil leakage or explosion. The epoxy resin is self-extinguishing and flame-retardant. This makes it ideal for high-density areas such as:
- High-rise office buildings.
- Hospitals and medical centers.
- Underground subways and tunnels.
Low Maintenance and High Durability
With no oil levels to monitor or gaskets to replace, the maintenance requirements for a cast resin transformer are minimal. The solid insulation provides excellent resistance to short-circuit forces and mechanical stress, ensuring a service life often exceeding 20-30 years.
