Tenarc designs, manufactures, and delivers IEEE/ANSI-compliant transformers and grid equipment — on a schedule you control.
Generator, auto, interconnecting, and STATCOM transformers for transmission, generation, and utility substations. KEMA dynamic short-circuit tested up to 500 MVA.12 units cleared at CPRI on first attempt.
Oil-filled, pad-mounted, and hermetically sealed units for commercial, industrial, and utility networks. IEEE-compliant pad-mount designs available for US installations.
Multi-winding inverter duty transformers purpose-built for solar, wind, and energy storage — available in 2 to 7 winding configurations. 12+ GW installed globally.
Voltage regulation and harmonic control reactors for EHV transmission systems. Technology licensed from Fuji Electric for 400 kV and 765 kV shunt reactors.
Furnace (EAF, SAF), rectifier (up to 160 kA DC, 24-pulse), traction, and generator duty transformers for harsh industrial environments. Up to 400 MVA furnace duty.
Natural ester fluid-filled transformers up to 400 kV — biodegradable and fire-resistant. Plus unitised packaged substations for plug-and-play deployment up to 2,500 kVA.
Scale power infrastructure to match compute demand growth.
Connect solar, wind, and storage to the grid on schedule.
Replace aging transformers and expand grid capacity.
Accelerate project timelines with reliable supply.
You share your requirements — voltage class, MVA rating, quantity, applicable standards, and delivery timeline. Our engineering team reviews the specifications, confirms design parameters, materials, and IEEE/ANSI compliance requirements. We provide budgetary pricing within 5 business days.
Detailed design drawings, General Arrangement (GA) drawings, and engineering documentation are prepared and submitted for your review and approval. Includes thermal calculations, impedance analysis, and BIL coordination.
Production at ISO 9001/14001/45001-certified facilities with in-process quality inspections at every stage — core stacking, winding, assembly, tanking, and oil processing. Climate-controlled winding shops with positive air pressure ensure dust-free assembly.
Comprehensive routine and type testing at NABL-accredited laboratories — including ratio, polarity, insulation resistance, lightning impulse (BIL), partial discharge, temperature rise, and short-circuit withstand. Full test reports provided.
Optional buyer-witnessed testing or independent third-party audit before dispatch. We coordinate all logistics for factory visits and can facilitate remote video witnessing of critical tests including impulse, PD, and temperature rise.
Export-grade maritime packaging with nitrogen-filled tanks for ocean transit. Shipped via deep-water ports (Mundra, Nhava Sheva) with heavy-lift capability. West Coast delivery in 25–30 days, East Coast/Gulf in 35–45 days.
Complete import compliance management — HTS classification, tariff analysis, duty optimization, customs clearance documentation, and coordination with US port authorities. Landed-cost estimate provided upfront with no surprises.
Specialized heavy-haul transport from US port to your project site. Route surveys, permitting, escort vehicles, and crane coordination for transformer offloading and placement on foundation.
On-site erection support, oil filtration and processing, bushing installation, winding resistance and ratio verification, insulation testing, and energization. Commissioning engineers available for supervision and technical guidance through first energization.
Warranty coverage, periodic Dissolved Gas Analysis (DGA) guidance, Frequency Response Analysis (FRA), field diagnostics, and repair services. On-site Mobile Vapour Phase Drying (MVPD) available for units up to 500 MVA. Tenarc remains your single point of contact throughout the transformer's service life.
OngoingSteps 1 through 9 — from your spec sheet to an energized distribution transformer on your site — in under 12 months.
