Prince PowerTech designs and builds indoor, outdoor and packaged electrical sub-stations for factories, commercial buildings, RMG units and infrastructure projects. From single-line design and load study to transformer supply, HT/LT switchgear, protection, erection and commissioning — every stage is delivered as a complete, standards-compliant package by our licensed engineers.
We engineer the right configuration for your load, space and budget — assembled from proven HT and LT equipment and fully protected switchgear.
Compact indoor and unit (package) sub-stations for factories and commercial buildings where space is limited — transformer and switchgear in a single, safe enclosure.
Plinth or structure-mounted outdoor sub-stations for larger industrial loads, with weatherproof HT equipment, transformers and dedicated earthing.
11/0.4 KV step-down distribution sub-stations delivering a stable, usable 400/230 V supply to your machinery, lighting and building services.
Load calculation, single-line diagrams, transformer sizing and layout drawings tailored to your demand and future expansion.
Oil-immersed (ONAN) and dry-type transformers from 100 kVA to 2500 kVA, sourced from reputable manufacturers.
VCB, LBS, HT panels and LT distribution boards with ACB/MCCB — assembled, wired and tested to specification.
Numerical protection relays, CT/PT, over-current, earth-fault and differential protection with proper coordination.
Automatic PFI plant and capacitor banks to raise power factor to 0.95+, cut penalties and reduce demand charges.
Transformer oil (BDV) test, relay testing, insulation and earthing tests, energization and full handover documentation.
