20 Dry-Type Transformers + 10 Box-Type Substations for an International Airport in Qatar
Project Overview
HBTP supplied 20 + 10 substations units of SCB13-1600/10 transformers for an airport expansion increasing capacity to 60 million passengers annually in Doha, Qatar. The project represents a significant deployment in the international airport sector, requiring transformers engineered for reliable operation under demanding conditions.
Project Background
International airports are critical infrastructure requiring maximum power reliability for runway lighting, terminal systems, baggage handling, and air traffic control. This expansion project demanded robust power distribution for Qatar's extreme desert climate with 50°C ambient temperatures.
Customer Requirements
1600kVA dry-type transformers, 10kV/0.4kV ratio, F1 fire resistance, 50°C ambient rating, low noise for terminal areas, box-type substations with integrated cooling for outdoor airfield applications, and compliance with IEC and Qatari standards.
Our Solution
HBTP supplied its SCB13-series transformers, engineered specifically for international airport applications. The high-quality CRGO silicon steel core with step-lap mitered joints minimizes no-load losses, while copper windings provide enhanced short-circuit withstand capability and long service life.

Quality & Testing
All units passed high-temperature testing at 50°C ambient. The box-type substations underwent thermal performance verification to ensure adequate cooling under extreme conditions. Sound level testing confirmed ≤58dB(A) for terminal-adjacent installations.
Delivery & Installation
Equipment was delivered in phased shipments to align with the airport's expansion timeline. HBTP provided 24/7 on-site support during the critical commissioning phase before airport opening.
Project Outcomes
All 20 + 10 substations transformers were successfully energized and are operating at rated capacity. The project was completed on schedule, and the customer has reported excellent performance with no unplanned outages attributed to transformer equipment. HBTP's reliable power distribution solution has contributed to the project's overall success and operational efficiency.
