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:
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.
