HV power transformer

Power transformers & HV substations, engineered to order

Above roughly 50 kV, projects move into HV (HTB) territory: power transformers, HV switchgear, protection and civil works, each studied case by case. These are not catalogue items — they are engineered to your single-line diagram, your DSO's prescriptions and your site constraints, then built, factory-tested (FAT) and delivered turnkey.

Frequently asked

What voltage range do you cover?

HV substations and power transformers are addressed on a study basis, typically from 36 kV up into the HV range. Each project is scoped against your single-line diagram and DSO requirements.

Is a factory acceptance test included?

Yes — FAT in the factory is standard on power transformers, and independent witness testing (KEMA / TÜV) can be arranged. The test programme is agreed at quotation.

Do you deliver turnkey?

Yes — from study and manufacturing through abnormal-load transport, erection and on-site commissioning, with a single point of accountability. The exact scope is defined in the quotation.
