Key Features & Advantages
Our oil-immersed distribution transformer stands out with advanced engineering that ensures superior performance, energy savings, and durability. Built to serve as a robust power distribution transformer, it delivers consistent power to end users while minimizing operational costs.
• Advanced Core Technology
Uses high-permeability silicon steel with a full oblique seven-step lap joint structure. This uniform magnetic flux distribution significantly reduces no-load excitation current and no-load losses for maximum efficiency.
• Premium Windings
High and low voltage coils are wound with high-quality oxygen-free copper wire in a multi-layer cylindrical structure, ensuring excellent electrical conductivity and mechanical strength.
• Fully Sealed Tank Design
The corrugated radiator and hermetically sealed oil tank create an attractive, compact footprint with superior heat dissipation. No conservator needed, eliminating moisture ingress and extending insulation life.
• Optimized Cooling System
Axial oil ducts inside the windings direct oil flow toward high-temperature zones, achieving excellent heat dissipation, lower temperature rise, and higher overload capacity.
• Robust Mechanical Structure
Axial clamping, special lifting plates, and advanced fastening systems allow the transformer to withstand transportation shocks. The no-core-lifting design saves time and cost during installation and maintenance.
• Eco-Friendly & Low Noise
Operates with minimal noise, low temperature rise, and zero environmental pollution. High efficiency and maintenance-free operation make it ideal for modern power networks.
These features make our electrical power distribution transformers a trusted choice for utilities and industries seeking reliable, energy-efficient solutions comparable to premium cooper power transformers.
