THE ESTABLE APPROACH
A transformer should fit the system, not force the system to fit the catalogue.
ESTABLE matches equipment requirements to the right transformer or power-conversion product. Each project starts with the application and moves through an approved drawing, sample, test plan and controlled production release.
PRODUCT SYSTEMSEight product groups.
Eight product groups.
One point of technical responsibility.
From 20 VA compact transformers to selected 20 kVA formats, each product is selected as part of the complete power system.
01
TOROIDAL TRANSFORMERS
Toroidal Transformers
Custom toroidal transformers from 20 VA upward, with selected formats to 20 kVA, adapted to the equipment envelope.

THREE WAYS TO SPECIFY
Start from what you know.
01 / STANDARD
Choose a published range.
Power, voltage and dimensions are already defined. Confirm fit and availability.
Search standard ranges 02 / MODIFYAdapt the standard.
Change a winding, terminal, mounting height, insulation class or enclosure.
Configure the requirement 03 / REPLACEReconstruct the requirement.
Begin with a drawing, nameplate, failed unit or incomplete legacy specification.

FROM REQUIREMENT TO EVIDENCE
Every critical assumption has a place in the file.
The specification, drawing, sample and production record remain connected. That makes changes visible and repeat orders easier to control.
- 01Review
We organize the drawing, nameplate, application and missing data.
- 02Specify
The electrical and mechanical route is confirmed by an engineer.
- 03Sample
A paid sample is checked for form, fit and function.
- 04Produce
Approved configuration, test records and batch documentation.
MANUFACTURING EVIDENCE
Look beyond the render.
Winding, encapsulation and dielectric testing are visible parts of our production route. Manufacturing and inspection are carried out in ESTABLE's production operation.
ENGINEERING POSITION
Do not hide the difficult questions. Resolve them before the build.
Applicationdefines the starting point
Evidencesupports the specification

A practical checklist for replacing a failed transformer when drawings or the original supplier are unavailable.
NAMED PROJECT CONTACT
One person owns the technical review.
Send the drawing, nameplate or complete application file directly to the project lead. We will confirm the next technical step and identify any missing information.
START WITH WHAT YOU HAVE
A drawing is useful.
