Product Overview
The HENTG POWER 500kVA 33kV/0.4kV oil immersed distribution transformer is designed for reliable and efficient power distribution in medium-voltage systems. Utilizing advanced silicon steel core technology and high-quality copper windings, the transformer delivers stable performance under varying load conditions.
With ONAN cooling, it ensures effective heat dissipation without requiring auxiliary cooling equipment, making it ideal for outdoor and industrial applications.
Performance Advantages
Low No-load Loss & Load Loss
Designed with high-permeability silicon steel core and optimized winding structure, the transformer significantly reduces no-load loss and load loss. This improves overall energy efficiency, lowers operating costs, and meets international energy-saving standards. Ideal for long-term continuous operation in distribution networks.
High Short-circuit Strength
The transformer is engineered with reinforced winding structure and strong mechanical support to withstand high short-circuit currents. Advanced clamping design ensures structural stability during fault conditions, enhancing system reliability and safety in industrial and utility applications.
Excellent Overload Capability
Stable Voltage Regulation
Precision-designed winding ratio and strict manufacturing tolerances ensure excellent voltage regulation performance. The transformer delivers stable output voltage under varying load conditions, protecting downstream equipment from voltage fluctuation risks.
Low Noise Operation
Using high-quality silicon steel laminations and vibration-reduction structural design, the transformer operates with low acoustic noise levels. Suitable for urban substations, commercial areas, and noise-sensitive environments.
Long Service Life (20+ Years)
Manufactured with high-grade materials, hermetically sealed tank design, and anti-corrosion surface treatment, the transformer ensures long-term durability even in harsh environments. With proper maintenance, service life exceeds 20 years, providing reliable return on investment.
