Why Lahore Factories Rely on TransfoLine for Urgent Repairs.
When a 500 kVA or 1000 kVA substation fails, downtime costs millions of PKR per day. We eliminate the wait with local infrastructure, certified materials, and immediate temporary power.
Complete Overhaul & Rewinding Capabilities in Lahore.
From distribution step-down units to heavy industrial steel melting transformers, we handle full electrical and mechanical restoration conforming to IEC 60076 and WAPDA DDS-84 standards.
HT & LT Coil Rewinding (Electrolytic Copper)
We strip burnt windings down to the core and rebuild using 99.99% pure electrolytic copper flat strips or enameled wire. Layered with Class H Nomex and thermally upgraded Kraft paper, coils undergo vacuum varnish impregnation and 16-hour controlled oven baking to eliminate voids and moisture.
Core De-Stacking, Lamination & Re-Insulation
Severe flashovers cause inter-laminar short circuits in CRGO silicon steel cores, leading to excessive iron losses and overheating. We de-stack core limbs, deburr, recoat insulation varnish, re-clamp under calibrated torque, and restore baseline magnetic flux.
On-Site High-Vacuum Oil Dehydration & BDV Restoration
Humid Lahore monsoons degrade transformer oil rapidly. Our mobile vacuum dehydration plants heat, degas, and filter insulating oil under deep vacuum (< 0.05 mbar) directly at your substation, elevating dielectric breakdown voltage from an unsafe 20 kV back to factory-certified > 65 kV.
Bushing, Tap Changer & Tank Leak Overhaul
Over 40% of transformer breakdowns in Lahore start with gasket hardening, leaking oil sight glasses, or burnt tap changer contacts. We replace brittle gaskets with oil-resistant Nitrile cork, service off-circuit tap changers (OCTC), and renew cracked HT porcelain bushings.

LOGISTICS How quickly can your repair crew reach our factory in Lahore?
For all major industrial zones in Lahore—including Sundar Industrial Estate, Kot Lakhpat (Quaid-e-Azam Industrial Estate), Multan Road, and Sheikhupura Road—our mobile diagnostic testing van arrives within 2 to 4 hours of your emergency call. For factories near Raiwind Road or Manga Mandi, response time is under 90 minutes.
PRICING What is the average cost to rewind an industrial transformer in Lahore?
Rewinding costs depend primarily on the kVA capacity and the weight of copper required. As a baseline in 2026, rewinding a standard 200 kVA distribution transformer ranges between PKR 180,000 and PKR 320,000, while a 630 kVA or 1000 kVA industrial unit ranges from PKR 450,000 to PKR 950,000. Costs are determined by whether single-phase or all three phases need rewinding and whether core de-stacking is required. We provide a guaranteed upfront quotation before commencing work.
LOANER Can TransfoLine provide a standby loaner transformer during repair?
Yes, absolutely. This is one of TransfoLine's greatest competitive strengths. We maintain an inventory of over 50 ready-to-dispatch certified transformers at our Raiwind Road yard (50 kVA to 2500 kVA). If your factory cannot afford a 48-to-72-hour shutdown while rewinding takes place, we crane-deliver and temporarily hook up an emergency loaner unit so production never stops.
TECHNICAL What grade of copper do you use for coil rewinding in Lahore?
We strictly use 99.99% pure electrolytic grade copper winding wire with Class H Nomex or diamond-dotted Kraft paper insulation. We never use cheap re-melted scrap copper or aluminium substitutions commonly found in informal roadside repair shops on Bund Road. Pure copper ensures lower I²R losses, superior thermal dissipation, and long operational life.
COMPLIANCE Do you provide official LESCO test and compliance reports?
Yes. Every repaired and rewound transformer undergoes rigorous high-voltage test bay validation including turns ratio, winding resistance, insulation Megger testing, and dielectric oil BDV breakdown tests conforming to WAPDA DDS-84 and LESCO grid requirements. You receive an official stamped test certificate suitable for utility audits and insurance claims.
ON-SITE Can minor transformer faults and oil leaks be repaired on-site?
Yes. Gasket replacements, bushing renewals, tap changer contact maintenance, silica gel breather recharging, and on-site high-vacuum oil filtration can be completed directly at your substation without transporting the transformer, saving significant crane and freight costs.
