Manufacturing Is Our Competitive Moat
Most EPC contractors in India source switchgear and cables from third-party vendors — creating delivery delays, quality variability, and split accountability. DEC manufactures both in-house, giving our clients:
Faster Delivery
In-house manufacturing means panels and cables arrive in sync with civil progress — not weeks behind.
Tighter Quality
Every panel and cable is factory-tested before shipping — documented, traceable, guaranteed.
Single Accountability
One contract, one team, one accountability point from design through supply through commissioning.
Custom Specs
We manufacture to your exact project specifications — not off-the-shelf catalogue products.
Trisquare Switchgear Manufacturing
Trisquare Switchgear's manufacturing facility at Kundli Industrial Area produces the complete range of MV and LV switchgear, control panels, motor control centres, and distribution boards that power every DEC EPC project.
The facility is equipped with modern fabrication machinery, powder coating lines, bus bar manufacturing, and a dedicated testing area where every panel undergoes routine type tests before dispatch.
POLYVION Cable Manufacturing
POLYVION Cables & Wires manufactures a comprehensive range of electrical cables and wires at its Kundli facility. Producing cables to IS, IEC, and BS standards, POLYVION supplies the cable requirements of DEC projects — ensuring consistent quality, fast delivery, and the ability to manufacture to custom specifications.
