Frequently Asked Questions
Where is a 630 kVA Indoor Dry-Type Transformer normally installed?
It is built for indoor commercial, industrial and data-center distribution. This unit is configured with 10/11 kV primary and 400 V secondary and AN cooling.
Can you change the rating or voltage of this indoor dry-type transformer?
Yes. Ratings are set from your project, not from a fixed catalogue. Send the single-line diagram and load list and we size the windings, tap range, cooling and protection to what the site actually needs. Vector group, frequency and terminal arrangement are confirmed on the drawing before anything is built.
Which standard applies to this indoor dry-type transformer, and is it certified?
The applicable standard and the clause set are agreed against your project specification before production starts. Where a project names IEC 60076 for the transformer or IEC 62271-202 for a prefabricated substation, we work to those clauses and ship the routine test report with the unit.
What cooling and protection are fitted?
Cooling is AN. Protection and monitoring are selected to the single-line diagram: winding temperature sensors with a thermostat and trip contact, forced-air fans where the load profile needs them, and surge arresters on the terminals. Indoor or outdoor placement, enclosure rating and foundation details are fixed with your site conditions.
What information should we send for a quotation?
The single-line diagram, the load list, the system voltage and frequency, and the site conditions that affect the design – altitude, ambient temperature range, indoor or outdoor, enclosure rating. With that we come back with a drawing and a price. If you only have a rating in mind, send that and we will work the rest out with you.
