Manufacturing & Services

Manufacturing of Disconnectors

Manufacturing of Disconnectors and Switches : iSAT stands at the intersection of global heritage and Indian manufacturing excellence. Under license from Coelme-Egic (Italy) and Southern States LLC (USA), iSAT manufactures a comprehensive range of Disconnectors and switching systems up to rated voltage of 800kV. Our production process brings well-proven international designs to the Indian market without compromising on technical foundation or craftsmanship.
Each unit is backed by over a century of innovation. Vast options are available from the range of designs of Disconnectors available in our product range. The switchers being introduced in Indian transmission sector is going to be a game changer. We will offer on-load disconnectors up to rated voltage of 245KV never ever seen before by Indian market. The switchers will resolve the problem of unsolicited operations of Circuit Breakers merely for isolation of circuit. The restriking and Transient recovery voltages induced due to Circuit breaker operations reduces the life of Power system insulation over a period of time, which should ideally be used only for protection interruption.
Each one of us and our partners bring together a rich legacy of technical know-how in Electrical application engineering to accelerate the growth of Indian aspirations for smart and reliable grid systems.

Manufacturing of Railway Switches

As India accelerates toward a smarter, more reliable grid, iSAT provides the specialized switching technology required for critical railway infrastructure. Our railway-specific portfolio is engineered to handle the unique stresses of traction power, ensuring seamless isolation and protection for catenary systems.

Application-Specific Design: Specialized Catenary Switches and isolation systems designed for Transmission, Distribution, and Generation within the railway sector.

Technical Know-How: We translate decades of European and American application engineering into “Made in India” solutions that support the aspirations of a modernizing rail network.

Proven Reliability: By leveraging the combined expertise of our global partners—dating back to the establishment of EGIC (1916) and COELME (1950)—we deliver switchers that guarantee long-term operational stability.

High Power Labs :

We design and build facilities for testing the performance and safety of electrical equipment under high power conditions, such as short-circuit and switching tests. We possess a blend of electrical engineering expertise, hands-on lab experience, and specialized knowledge in high- power and high-voltage testing in compliance to IEC and ANSI standards. We have delivered online high power labs successfully to numerous customers in India from concept designing to supply , erection, testing and commissioning. The turbo generators manufactured in India, with capacities up to 1565 MW—be it for thermal or nuclear applications—must have been delivered to you after undergoing ‘Sudden short circuit testing’ in accordance with IEC 60034 standards at the specialised facilities established by iSAT.
