FAQS

ETT is a manufacturer, not a reseller. Transformers are engineered, wound, assembled, oil-filled, and tested at ETT’s own 12,000 sq. mtr. manufacturing facility, with dedicated departments for fabrication, winding, testing, and dispatch.

ETT’s manufacturing plant is located near Indore, Madhya Pradesh, at Survey No. 77/3, Gram Ujjain, Tehsil Sanwer, Mundla Husain, Indore.

ETT has been manufacturing transformers since 2014, giving it over a decade of experience in transformer design, production, and after-sales service across government and private sector projects.

ETT has supplied transformers to 294+ government projects and works with a distributor network of 200+ partners across India as of 2026.

An On-Load transformer allows the voltage tap position to be changed while the transformer is energized and carrying load, useful for continuous operations. An Off-Load transformer requires the unit to be de-energized before adjusting the tap position, and is typically used where voltage fluctuation is less frequent.

A dry-type transformer uses air or resin insulation instead of oil, making it safer for indoor use, hospitals, data centers, and locations where fire risk from oil-filled units must be minimized. ETT began manufacturing dry-type transformers in 2026 to meet growing demand for compact, low-maintenance indoor power solutions.

A Compact Substation (CSS) Transformer combines the transformer and switchgear into a single compact, factory-assembled unit, designed for space-constrained sites such as commercial buildings, townships, and urban infrastructure projects where a full conventional substation isn’t practical.

A furnace transformer is a specially designed transformer built to supply the high, fluctuating current loads required by industrial furnaces, commonly used in metal, steel, and manufacturing industries where standard distribution transformers aren’t suited to the load profile.

ETT manufactures transformers ranging from smaller distribution units (such as 25 KVA and 63 KVA) up to higher-capacity power transformers, including 5 MVA, 8 MVA, and 10 MVA units, following its 2025 facility expansion.

Yes. ETT offers custom-engineered transformer solutions built to a client’s specific voltage rating, capacity, and application requirements, in addition to its standard product range.

Every transformer is tested in-house using NABL-accredited testing procedures before dispatch, covering electrical performance, insulation integrity, and compliance with BIS and IEC standards.

ETT manufactures transformers using 99.9% pure copper and high-grade core materials, built to current BIS, BEE, and IEC standards for durability, low losses, and long operational lifespan.

Yes. ETT’s transformer range includes both outdoor and indoor-ready configurations, allowing selection based on the site’s space, environmental exposure, and safety requirements.

Yes. ETT manufactures transformers suited to renewable energy applications, including solar power installations, as part of its industrial and infrastructure product range.

Yes. ETT has an established track record supplying distribution and power transformers to government electricity boards and has completed 294+ government projects to date.

Yes. Alongside manufacturing new transformers, ETT also repairs and refurbishes transformers, with a significant number of units serviced annually as part of its operations.
