Weatherproof 125kVA 10kV to 400V Outdoor Pole Mounted Oil-immersed Power Transformer for Reliable Community Power
125kVA pole-mounted transformer for reliable community power. Weatherproof design withstands harsh environments with IEC-certified performance. Features low-loss core, maintenance-free operation, and customizable voltage options.
HENTG 125kVA 10kV to 400V Outdoor Pole Mounted Distribution Transformer is engineered for high-performance community power distribution. This oil-immersed unit is specifically designed for long-term outdoor reliability, converting medium voltage into stable low voltage for residential and commercial grids. With a robust weatherproof enclosure and optimized cooling, it ensures uninterrupted power even in the harshest environmental conditions.
- Superior Weatherproofing: Fully sealed structure with anti-corrosive coating, rated for extreme outdoor exposure
- High-Efficiency Performance: Low-loss silicon steel core design, significantly reducing operational costs and heat generation
- Compact Pole-Mounted Design: Optimized for easy installation on utility poles, saving ground space and reducing civil engineering costs
- Maintenance-Free Longevity: High-quality mineral oil and advanced sealing technology extend the service life to over 20 years
- Climate Resilience: Specifically reinforced for high-temperature and sandy environments (Ideal for Africa and the Middle East)
| Rated Capacity | 125kVA |
| Voltage Ratio | 10kV / 0.4kV (Customizable) |
| Connection Symbol | Dyn11 / Yyn0 |
| Cooling Method | ONAN (Oil Natural Air Natural) |
| Insulation Level | LI75 AC28 / AC3 |
| Standard Compliance | IEC 60076 / IEEE C57.12 |
| Tank Design | Corrugated tank for optimized heat dissipation and pressure flexibility |
| Bushing Material | High-creepage porcelain or epoxy resin for sand-storm resistance |
Problem: In sandy regions like many African countries, fine dust accumulates on seals, and extreme temperature fluctuations cause traditional gaskets to brittle, leading to oil leakage and transformer failure.
HENTG Solution:
- Advanced Sealing Material: High-grade Fluorine Rubber (FKM) or Nitrile Butadiene Rubber (NBR) gaskets that maintain elasticity in 50°C+ heat and resist dust erosion
- Double-Weld Tank Integrity: Transformer tank undergoes dual-seam welding process and high-pressure leakage test to ensure 100% hermetic seal
- Enhanced Anti-Sand Bushing Covers: Protective caps prevent dust accumulation on porcelain bushings, reducing risk of flashover caused by conductive dust
Yes. We use high-flash-point insulation oil and a corrugated tank design that increases the cooling surface area by 30%, ensuring stable operation at 50°C ambient temperatures.
Every unit undergoes a 0.5 bar pressure test for 24 hours. We use high-strength bolts and precision-machined flanges to ensure the seal remains intact.
Our products are designed according to IEC 60076 standards, which are widely accepted by African power authorities (e.g., ZESCO, KPLC, ESKOM).
For standard 125kVA units, our lead time is 25-30 days, supported by our 100,000 m² factory capacity.
Absolutely. We provide detailed installation manuals, 2D/3D drawings, and remote video technical support for site commissioning.
We offer a standard 24-month warranty and provide a localized spare parts list for long-term projects.
