EPC SCOPE What is included in a Turnkey 11kV Substation EPC contract with TransfoLine?
Our turnkey scope includes complete electrical engineering design, transformer manufacturing/supply (25 kVA–10 MVA), HT Vacuum Circuit Breaker (VCB) panels, LT distribution switchgear, PFI plants, deep-bored earthing grid (≤ 1Ω), 11kV cabling, civil pad works, pre-commissioning testing, and WAPDA/DISCO grid energization under a single warranty.
TIMELINE How long does it take to design, install, and energize an industrial substation?
Standard distribution substations (200 kVA to 1,000 kVA) are completed and energized within 14 to 21 working days. Large industrial substations (1.5 MVA to 5 MVA) require 25 to 35 working days depending on utility approval lead times.
APPROVALS Does TransfoLine handle DISCO (LESCO, K-Electric, FESCO, MEPCO) utility approvals?
Yes. Our engineering team prepares complete Single Line Diagrams (SLD), protection relay coordination curves, transformer type-test certificates, and earthing reports required for rapid utility inspection and meter sealing.
