At Amtech Power, we offer comprehensive SITC (Supply, Installation, Testing & Commissioning) solutions for VCB (Vacuum Circuit Breaker) Panels and RMUs (Ring Main Units), tailored for medium-voltage applications at 11kV, 22kV, and 33kV. Our services ensure safe, efficient, and reliable power distribution across industries, utilities, commercial buildings, smart grids, and infrastructure projects.
VCB Panels use vacuum interrupters for safe fault clearance and require minimal maintenance, making them ideal for substations and industrial applications. RMUs are compact, sealed switchgear units suited for ring networks, offering fault isolation, load switching, and operational continuity in space-constrained environments.
We provide equipment from top-tier OEMs including Siemens, ABB, Crompton Greaves, and Lucy Electric, backed by expert execution. Whether it’s panel design, foundation, cable termination, relay configuration, or SCADA integration, our in-house team handles everything with precision and compliance to global standards (IS/IEC).
Our offerings are backed by 20+ years of experience, A-Class government certifications, and optional AMC and retrofitting support for ongoing reliability. From project planning to final commissioning and training, Amtech Power delivers a trusted, turnkey solution for all your medium-voltage switchgear needs.
We specialize in the Supply, Installation, Testing & Commissioning (SITC) of VCB Panels and Ring Main Units (RMUs) for medium voltage applications at 11kV, 22kV, and 33kV. Our solutions ensure safe, reliable, and efficient power distribution for utilities, industries, commercial establishments, and infrastructure projects.
We provide products from top global manufacturers including Siemens, Crompton Greaves (CG), ABB, and Lucy Electric, combined with expert project execution and comprehensive maintenance services.
A VCB (Vacuum Circuit Breaker) Panel is a medium-voltage switchgear unit using vacuum interrupters to safely interrupt fault currents, providing reliable protection and operational efficiency with minimal maintenance.
An RMU is a compact, sealed switchgear assembly designed for ring network configurations, enabling quick fault isolation and enhanced reliability in a compact footprint.
