55 Units of S13-3150kVA/110kV Transformers for a Refinery in Saudi Arabia

Project Overview

HBTP supplied 55 units of S13-3150/110 transformers for a major refinery expansion processing 400,000 barrels per day in the Eastern Province, Saudi Arabia. The project represents a significant deployment in the petroleum refining sector, requiring transformers engineered for reliable operation under demanding conditions.

Project Background

Saudi Arabia's downstream oil sector continues to expand, with major refineries upgrading their power infrastructure to support increased production capacity. This project required robust transformers capable of operating in extreme desert conditions with ambient temperatures reaching 50°C and high levels of sand and dust.

Customer Requirements

Our Solution

HBTP supplied its S13-series transformers, engineered specifically for petroleum refining 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 underwent extended temperature rise testing at 50°C ambient to verify performance under extreme conditions. Lightning impulse tests at 480kV (LI) and partial discharge measurements were conducted for every unit. Sand and dust ingress testing verified the sealing systems.

Delivery & Installation

The transformers were shipped via sea freight from Tianjin to Dammam, with total delivery time of 10 weeks including production. HBTP dispatched a team of engineers to supervise installation and commissioning over a 3-month period.

Project Outcomes

All 55 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.
