About / Customer Cases

Scopes we have actually delivered.

A transformer order is a chain of small decisions: grade, slit width, coating, packing, documents, delivery. These are representative engagements where the whole chain had to hold.

Client names withheld. Profiles describe representative programme scope; commercial figures are agreed targets, not audited results.

A second CRGO source for a 220 kV power transformer line

Featured engagement

Power transmission/Central Europe

A second CRGO source for a 220 kV power transformer line

A European OEM needed to lift core-steel volume by roughly a third without re-qualifying its core design or adding a second inspection process.

Challenge: The existing mill allocation could not cover the order book. Any new source had to match the current loss grades, coating and slit-width tolerance, and arrive with test data the customer's engineering team already trusted.
Scope: 23QG085–30Q120 laser-scribed CRGO, slit to 12 widths
Mill certificate and loss-test data matched coil by coil
Dimensional and coating checks before export packing
Consolidated container with core steel and winding wire
Outcome: Second source qualified without changing the core design
One document set covering two material families
Release inside the buyer's ten-week production window

Distribution/Middle East

Amorphous core kits for a desert distribution programme

A distribution transformer builder moved part of its range to amorphous cores to hit no-load loss targets, while keeping the same tank and winding design.

Challenge: Amorphous ribbon is sensitive to handling and annealing. The buyer needed wound cores that would survive sea freight and site storage in high ambient temperatures, from a supplier able to document every cast.
Scope: Iron-based amorphous ribbon to the buyer's width and thickness
Wound cores with stress-relief annealing records
Humidity-controlled export packing
DDP delivery to the customer's assembly yard
Outcome: No-load loss target confirmed on first-article cores
Core dimensions matched the existing coil former
Single delivery schedule across four core sizes

Dry-type transformers/Southeast Asia

One insulation package for a dry-type transformer plant

A dry-type manufacturer was buying resin, insulation paper and winding wire from three suppliers, with three lead times and three document sets.

Challenge: Humidity during the rainy season caused incoming insulation material to arrive out of specification. The plant wanted one supplier accountable for packing, desiccant and inspection — not just price.
Scope: Cast resin and hardener matched to the existing process
Insulation paper, pressboard and winding wire
Moisture-barrier packing with desiccant and humidity indicators
Combined shipment on one bill of lading
Outcome: Incoming inspection moved to one gate
One lead time for the full insulation bill of materials
Fewer partial shipments and lower inbound freight

Repair & maintenance/Australia

A critical-spares programme for a transformer service network

Four service depots needed fast access to gaskets, valves, bushings and winding wire without holding a full inventory at every site.

Challenge: Emergency repairs could not wait for a consolidated container. The network needed a shared stock list, a clear air-freight trigger and one point of contact across depots.
Scope: Critical-spares list agreed per transformer class
Buffer stock held at the export hub
Sea freight for planned work, air freight for breakdowns
One weekly stock and shipment report to all depots
Outcome: Urgent lines dispatched by air within days of release
Duplicate depot stock reduced
One commercial contact for four locations

Automotive materials/Mexico

Copper busbar and insulation for an automotive materials converter

A converter supplying EV busbar needed a China-based source for copper strip and heat-resistant insulation that could meet North American documentation requirements.

Challenge: The buyer's incumbent source quoted a lead time that did not match the launch schedule. Material had to arrive with traceability and RoHS documentation suitable for the customer's own PPAP file.
Scope: Copper strip and busbar to drawing
Heat-resistant insulation sleeving and film
Material certificates and RoHS declarations
DDP delivery to the Monterrey plant
Outcome: Launch volumes covered without a second PO cycle
Documentation accepted into the customer's PPAP file
One supplier for conductor and insulation
