Product Specification

High Light Low-Loss Core Oil Immersed TransformerHigh Mechanical Strength Windings Distribution TransformerHigh-Performance Insulating Oil Step-Down Transformer
Hermetically Sealed Oil-immersed 250KVA 315KVA Three-Phase Oil-Immersed Step-Down Distribution Transformer
HENTG POWER Hermetically Sealed Oil-immersed Distribution Transformer

Our 250kVA and 315kVA hermetically sealed oil-immersed distribution transformers are designed for dependable medium-voltage to low-voltage power delivery. The sealed tank structure eliminates oil leakage risks, improves heat dissipation, and ensures long-term stability even in harsh environments such as high temperature, humidity, and dust.

These three-phase step-down transformers are widely used in utilities, commercial facilities, industrial plants, rural electrification projects, and renewable energy systems. They feature low-loss core materials, high mechanical strength windings, and high-performance insulating oil to guarantee excellent efficiency and extended service life. Transformer installation example

Our Advantages
Type S13 Oil-Immersed Distribution Transformer Features

The Type S13 oil-immersed distribution transformer is widely used in residential areas, commercial centers, industrial parks, and rural electrification projects. Compared to S9 or S11, the S13 offers several improvements:

  • Higher Energy Efficiency: Lower no-load loss (20-30% reduction compared to S11) and lower load loss through improved winding structure and materials.
  • Improved Temperature Rise Performance: Enhanced oil circulation and cooling systems maintain stable operation under load, extending insulation life.
  • Reduced Noise Levels: High-permeability silicon steel and precision manufacturing lower magnetostriction for quieter operation.
  • Robust Mechanical Design: Optimized winding structure improves short-circuit resistance and reduces vibration.
  • Longer Service Life: Superior materials and structural improvements enable 20-30 years of service under proper conditions.
