Notes from the works.
Practical technical writing for the people who specify this equipment — what the standards require, where specifications go wrong, and how to compare quotations that look alike.
India’s transformer build-out: ₹6,000 crore of new factories announced in 2026, and what it means for buyers
Hitachi Energy, Siemens Energy and CG Power are adding power transformer capacity in Gujarat and Madhya Pradesh. Aditya Birla has entered cables with ₹1,800 crore. Where the money is going, and where it is not.
02Transformer lead times: a two-year queue abroad, an eight-month wait at home
Wood Mackenzie puts the average power transformer lead time at 128 weeks and the supply gap at 30 percent. Indian solar developers report eight-month waits. Why it is happening and how to buy around it.
0327 GW in six months: India’s solar record, and the transformers and transmission behind every megawatt
India installed a record 27 GW of solar in the first half of 2026 and passed 165 GW in total. Transmission and transformer supply are now the pacing items. The numbers, and what they mean for step-up and pooling equipment.
04IS 1180 energy efficiency levels: why “Level 2” is not what it was
Amendment 4 of 2021 deleted the loosest level and added two tighter ones. Today's Level 1 is what used to be called Level 2.
05Specifying a distribution transformer: the parameters that decide your tender
Rating and voltage are the easy part. The parameters that decide whether bids are comparable sit further down the schedule.
06What makes an inverter duty transformer different — and the number nobody publishes
A solar step-up transformer is not a distribution transformer with a different nameplate. Six things change — one is rarely on the datasheet.
07ACSR codewords: the reference table, and the mistake that costs tenders
Squirrel, Weasel, Rabbit, Dog, Wolf, Panther, Zebra, Moose — the animal names are half the story. Which part of IS 398 is the other half.
08A2XFY, A2XWY and 3.5 core: reading a cable designation properly
The letters are not decoration. Each is a construction decision, and two of them change the price of the cable substantially.
09IS 4759 or ISO 1461: what your galvanizing specification actually requires
One standard specifies coating mass, the other thickness. For the heaviest class they land in exactly the same place.
10Drip or sprinkler: choosing the right micro-irrigation for the crop
Drip is not always the answer, and the standard most suppliers cite for mini sprinklers is the wrong one.
