Project Overview

TSTY Electric’s Customized Solution

Engineered for Africa, Validated Globally

Project Overview

At the Port of Mtwara, Tanzania, a new modular power plant was being deployed to support port expansion and industrial operations. The project required 20 step-up transformers designed specifically for installation inside prefabricated electrical cabins—demanding precise mechanical dimensions, customized terminal configurations, and seamless integration with generators, switchgear, and control systems.

Key project requirements included

Custom physical specifications: exact footprint, color coding, and roof-mounted HV/LV bushings

Special design features: conservator-less (sealed) tank, adjustable no-load tap changer, and optimized cooling for confined cabin environments

Compliance with multiple international standards to satisfy EPC contractor and port authority requirements

Proven large-scale delivery capability from a supplier with global project experience

TSTY Electric’s Customized Solution

TSTY collaborated closely with the client through an iterative design process, delivering three refined technical proposals before finalizing a solution that met all spatial, electrical, and aesthetic requirements. Leveraging its multi-certification portfolio and flexible manufacturing system, TSTY produced 20 fully customized, oil-immersed step-up transformers—each engineered for reliable operation within the tight confines of a containerized power module.

Core Technical Adaptations

Conservator-less sealed tank for compact cabin integration

Roof-mounted HV/LV bushings for precise busbar alignment

Custom dimensions and color per client modular standard

Adjustable taps and multi-standard certifications included

Engineered for Africa, Validated Globally

Success in modular power projects hinges on precision, adaptability, and trust. This deployment demonstrated how deep collaboration and manufacturing agility can turn complex custom requirements into seamless execution.

Co-Engineering Drives Integration Success

Through three rounds of joint design reviews, the final transformer layout matched the cabin’s internal architecture exactly—avoiding costly field modifications or rework.

Global Certifications, Local Acceptance

With certifications aligned to international and East African standards, the units cleared customs efficiently and met all technical audits by the port authority and EPC contractor.

Optimized for Confined, Mobile Environments

The sealed, conservator-free design reduced height and maintenance needs—critical for long-term reliability inside enclosed, ventilated power cabins exposed to coastal humidity and salt air.

Scalable Delivery with Consistent Quality

From prototype to full batch, the production team maintained uniform quality across all 20 units, completing the order on schedule and supporting the port’s phased energization plan. TSTY’s ability to combine customization with volume execution made it a trusted partner in this strategic infrastructure project.
