Engineering EPC
We source and supply the full range of HT and LT electrical materials for substation, transmission line, and industrial projects — from transformers and HV switchgear to cables, conductors, relays, and meters — verified BIS-certified, with complete test documentation for DISCOM and CEIG acceptance.
Overview
Electrical material supply in AP and Telangana carries a risk that most clients underestimate: counterfeit and substandard materials with fake ISI marks are widespread — and CEIG inspectors or DISCOM teams will reject them on site, stalling the entire project. Every item we supply comes from verified manufacturers, carries an authentic BIS CML-numbered ISI mark, and is backed by type test and routine test certificates. For substation equipment, we align procurement to the AP DISCOMs' common Substation Specification & Regulation (SSR) approved vendor framework — so materials clear inspection without re-submissions.
Why Daakshyaani
APEPDCL, APCPDCL, and APSPDCL share a common Substation Specification & Regulation (SSR) that defines approved vendors, equipment ratings, and material standards. We procure to that framework — materials arrive with the right documentation and pass inspection without re-submissions.
Fake ISI-marked cables, transformers, and switchgear are prevalent in AP/TG markets. We verify every item against the BIS CML licence number database before acceptance — no fake marks, no counterfeit materials, no site rejections.
CEIG inspectors and DISCOM teams require type test certificates and unit-specific routine test certificates for major equipment. We package this documentation with every supply — so nothing is missing when the inspector arrives.
Direct relationships with BHEL, Crompton, Voltamp, Kirloskar, ABB, Schneider, Polycab, KEI, Sterlite, and Secure Meters — enabling faster lead times, competitive pricing, and access to equipment that smaller procurement channels cannot source.
Material supply can be bundled with our EPC erection and commissioning scope. The same team that specifies the equipment installs and commissions it — no handover gap, no specification mismatch between supplier and site crew.
A failed transformer or blown VCB at an industrial plant cannot wait weeks for tender procurement. We maintain relationships that allow fast-track orders for replacement equipment — minimising downtime for operating clients.

A Current Transformer (CT) steps down a large primary current to a small, measurable secondary current for metering and protection relays; a Potential Transformer (PT) does the same for voltage. Every HT metering point and protection scheme depends on correctly rated and calibrated CTs and PTs — undersized or mismatched units are a common reason a DISCOM or CEIG inspector rejects a metering panel at commissioning.
A Vacuum Circuit Breaker (VCB) is typically used in indoor HT panel boards for its compact size and reliable fault-clearing. A Ring Main Unit (RMU) is a sealed, gas- or air-insulated switchgear unit built for outdoor or compact secondary substation use, often where multiple feeders need to be looped in a ring configuration. The choice usually comes down to the substation layout and whether the installation needs to be indoor-panel-based or a compact outdoor unit.
A compact secondary substation packages a distribution transformer, RMU or switchgear, and LT panel into a single pre-fabricated enclosure — used where space is limited or a fast, standardised installation is needed, such as commercial complexes or industrial parks. They're increasingly common in utility tender specifications for 11kV/33kV distribution because they reduce on-site civil and electrical work compared to a conventional brick-and-mortar substation room.
Industries
We verify the BIS CML licence number against the manufacturer and product before supply, which is how counterfeit ISI-marked material gets caught before it reaches site.
Distribution transformers from 16kVA to 2500kVA (IS 1180) and power transformers from 5MVA to 315MVA (IS 2026), along with CTs/PTs across 11kV–220kV.
Yes — we source through the SSR (Substation Specification & Regulation) framework shared by APEPDCL, APCPDCL, and APSPDCL, the approved-vendor list DISCOMs themselves reference.
HT XLPE cables to IS 7098 Part 2 (11kV/33kV) and Part 3 (66kV), LT XLPE/armoured cables to IS 7098 Part 1, and ACSR/AAAC conductors to IS 398.
