H2: Full Range Dry Transformer & Cast Resin Transformer Products from Xinhong Electrical
As one of leading dry-type transformer manufacturers in China, our complete dry transformer portfolio covers low voltage (≤600V) and medium voltage (601V–34.5kV) models, including all mainstream types to satisfy diverse industrial and civil scenarios:
-
Cast Resin Transformer (Core Star Product)
Our epoxy cast resin dry transformer adopts vacuum pressure casting technology, fully encapsulating windings with high-strength epoxy resin. This model is the most popular choice when clients compare
oil immersed transformer vs cast resin, thanks to outstanding moisture-proof, dust-proof, flame-retardant and explosion-proof performance. Without flammable insulating oil, cast resin transformers eliminate leakage and fire hazards, perfectly suitable for underground substations, data centers, hospitals, coastal chemical plants and high-rise buildings.
-
VPI General Purpose Dry Transformer
Vacuum Pressure Impregnated dry transformer features good heat dissipation, easy maintenance and cost advantages, ideal for indoor clean industrial workshops, factory power distribution and standard commercial projects.
-
Special Custom Dry Transformer Series
We also supply substation type, pad mounted, drive isolation, harmonic mitigation, K-rated, marine duty, multi-pulse, noise attenuation, step-up and test dry transformers, supporting customized coil materials (aluminum/copper), low temperature rise, electrostatic shielding, forced air cooling and stainless steel enclosure options.
All our dry transformer units use high-grade grain oriented silicon steel cores, short-circuit resistant coil structure, UL-class insulation system, and complete 100% factory testing with certified test reports, complying with IEC, CE, ISO quality management systems.
H2: Oil Immersed Transformer vs Cast Resin Transformer – Key Comparison Guide
Many global clients inquire about the difference between oil immersed transformer and cast resin dry transformer. Xinhong Electrical sorts out core contrasts to simplify your project selection:
| Comparison Item |
Oil Immersed Transformer |
Cast Resin Transformer (Dry Transformer) |
| Safety Risk |
Flammable mineral oil, leakage & explosion risks |
Oil-free, self-extinguishing resin, zero fire hazard |
| Environmental Adaptability |
Poor for humid, salty, corrosive sites |
Excellent anti-moisture, anti-salt fog, anti-dust |
| Maintenance |
Regular oil replacement, sealing inspection |
Near maintenance-free long-term operation |
| Installation Space |
Need dedicated fire-proof transformer room |
Can be installed close to equipment, compact layout |
| Service Life in Harsh Environment |
Short, easy insulation aging |
Long stable service cycle |
| Representative Scenarios |
Outdoor open substations, remote utility grid |
Indoor buildings, data centers, underground, marine, chemical industry |
If your project requires high safety and low maintenance, cast resin transformer (a core type of dry transformer) is the priority solution from trusted dry transformer china manufacturers like xinhong electrical.
