Sustech on Electrical Engineering

At SUSTECH, we bring a wealth of expertise in Electrical, Control, and Instrumentation (EC&I) engineering, offering precise, innovative, cost-effective solutions that meet the diverse needs of clients and complex industrial projects. With a team of experienced engineers and cutting-edge technologies, we offer end-to-end services, from initial design and system integration to installation, commissioning, and ongoing support.

Our expertise covers the full range of electrical systems, from high and low voltage distribution design to detailed single-line diagrams, cable sizing, selection, fault current analysis, and step & touch potential calculations. We specialize in the design and optimization of earthing systems, substations, and lightning protection.

In the control and instrumentation domain, we provide complete support throughout the project lifecycle, including point-to-point wiring checks, function and loop checks, and the commissioning of process instrumentation and control systems. Our expertise extends to instrumentation calibration, hazardous area verification, and P&ID verification.

Our expertise in EC&I engineering ensures that your projects are executed efficiently, safely, and in full compliance with industry standards, delivering high-quality, reliable systems tailored to your unique requirements. Whether you're looking to design, implement, or optimize systems, we are dedicated to helping you achieve your goals with reliability and expertise.
