Transmission & Distribution HomeSectorsTransmission & Distribution STS Group began offering Transmission & Distribution (T&D) as a secondary service for the Data Center sector. Since then, we’ve expanded this capability to deliver turnkey solutions for both Air-Insulated Switchgear (AIS) and Gas-Insulated Switchgear (GIS). This growth reflects our commitment to diversification and our ability to apply engineering and project management expertise across critical infrastructure. Our T&D division brings deep experience and precision to every project. We understand the importance of a reliable power network. Our team is equipped to manage the complexities of AIS and GIS installations. We handle everything from feasibility studies and design to procurement, installation, testing, and commissioning.
