Product Description: HENTG 250KVA 10/0.4KV Oil-Immersed Three-Phase Distribution Transformer
HENTG - Powering Your World with Reliability and Efficiency Welcome to HENTG's premier outdoor distribution transformer, engineered for exceptional performance and durability in demanding environments.
This 250KVA, 10/0.4KV oil-immersed transformer is the ideal solution for commercial, industrial, and municipal power distribution networks.
Crafted with high-quality aluminum windings and a robust design, it ensures stable voltage transformation, enhanced safety, and long-term operational savings.
Trust HENTG to deliver the power infrastructure you need.
1. Superior Performance with High-Efficiency Aluminum Windings
Our transformer features high-conductivity aluminum material, offering an excellent balance of performance and cost-efficiency.
The design minimizes eddy current losses and ensures optimal heat dissipation, leading to higher operational efficiency and significantly lower energy costs over the transformer's lifespan.
Enjoy reliable 250KVA power capacity with reduced electricity waste.
2. Exceptional Durability for Harsh Outdoor Environments
Built to last, the sealed, oil-immersed construction provides superior insulation and cooling, protecting the core and windings from moisture, dust, and chemical contaminants.
The sturdy tank, high-quality oil, and corrosion-resistant exterior are engineered to withstand extreme temperature fluctuations, heavy rain, and other challenging outdoor conditions, ensuring uninterrupted service and minimal maintenance.
3. Enhanced Safety and Reliable Operation
Safety is paramount. The transformer is equipped with a conservator tank (oil expansion vessel) to accommodate insulating oil volume changes, preventing pressure build-up.
This design, along with its reliable insulating system, effectively prevents internal faults and reduces the risk of fire hazards.
It ensures stable voltage step-down from 10KV to 0.4KV, providing safe and secure power for your equipment and personnel.
Specifications:
Rated Capacity: 250 KVA Primary Voltage: 10KV (or 11KV, customizable) Secondary Voltage: 0.4KV (400V) Phase: Three Phase Type: Oil-Immersed, Outdoor Winding Material: Aluminum Frequency: 50Hz / 60Hz Tap Changer: Off-Circuit Tap Changer (Standard) Standards: IEC, ANSI, or as required
