Power transformer, HV switchgear and protection, engineered to order and delivered turnkey.
Tell us the product, approximate rating and your e-mail. We will review the requirement and identify any missing information. For voltages, delivery country and project details, use the full configurator.
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.
| Stage | Content | Indicative lead time |
|---|---|---|
| Study & sizing | single-line diagram, protection, civil works | 4 – 8 weeks |
| Manufacture & testing | power transformer, factory acceptance test (FAT) | per rating |
| Transport & commissioning | abnormal-load transport, erection, on-site tests | per project |
HV projects are handled on a study basis, schedule and pricing established case by case from your specification.
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.
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.
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.
| Scope | What the quotation needs to define |
|---|---|
| Enclosure | Concrete, metal or in-building arrangement is subject to the specification, manufacturing route and supporting evidence. A metal alternative needs the client’s approval. |
| Equipment and factory work | Transformer, switchgear, LV board, internal links and factory tests are itemised in the quotation. |
| Cable links between substations | Separate scope: route length, cable quantities per phase, conductor and screen ratings, fault current, clearing time, ducts and terminations must be checked against the interfaces at both ends. |
| Site work | Civil works, ducts, unloading, lifting, earthing, cable pulling, terminations, testing and commissioning are assigned explicitly to each party. |
| Documents and acceptance | Component reports do not by themselves demonstrate the complete assembly. The agreed dossier identifies applicable assembly verifications, drawings, routine tests and any type-test evidence. |
| Delivery and programme | Delivery point, Incoterm, import responsibilities and a project schedule are confirmed in writing. A generic transformer lead time does not establish a complete substation schedule. |
For EU MV switchgear up to and including 24 kV, the F-gas rules concern putting equipment into operation from 1 January 2026, with specified derogations. We study fluorinated-gas-free insulation with suitable switching technology. Vacuum interruption alone does not establish that insulation is SF6-free. Regulation (EU) 2024/573, Article 13.
