Integrated Power Distribution for Modern Infrastructure
At Mansha Tech, we specialize in the design, supply, and installation of Compact Sealed Substations (CSS) rated at 11/415 KV — engineered for high performance, compactness, and safety.
Our CSS units provide a fully integrated solution for medium voltage (MV) power distribution, combining the transformer, HT switchgear, LT switchgear, and protection systems into a single, factory-assembled enclosure.
These substations are ideal for projects that demand space optimization, reduced maintenance, and fast deployment while maintaining compliance with all electrical safety and performance standards.
What is a Compact Sealed Substation?
A Compact Sealed Substation is a prefabricated, factory-tested power unit designed to step down voltage from 11 KV to 415 V for distribution in commercial, residential, and industrial facilities.
It provides an all-in-one solution that is easy to install, environmentally safe, and highly reliable.
Main Components:
- HT Side: Ring Main Unit (RMU) or VCB Panel (11 KV)
- Transformer: Oil-cooled or Dry Type (up to 2.5 MVA)
- LT Side: ACB/MCCB-based Distribution Panel (415 V)
- Protection: Relays, meters, and fault indication systems
