MV transformers | Legrand United Kingdom

MV transformers

Our new Green T.HE Tier 2 transformers offer a very high quality product, with excellent performance and reduced losses, in full compliance with regulation 548/2014 and subsequent updates (EU regulation 2019/1783).

Distinctive design

Thanks to the use of innovative materials and the measures taken during their design, these transformers are characterised by the following distinctive features:

  • HV (high voltage) and LV (low voltage) terminals have been modified and built to facilitate the connection of the product on both winding
  • The HV windings are all made in BIL LIST 2, thanks to the reinforced insulation in the critical points of the unit
  • They guarantee very high performance and reduced losses compared to previous models, while maintaining equivalent weights and dimensions. All this is possible thanks to the completely new magnetic core with newly developed and high-performance materials

Meeting the Ecodesign Directive

The latest amendment to the European Commission’s Ecodesign Directive outlines the parameters transformers must adhere to in order to meet efficiency requirements, detailing the maximum load and no-load losses a transformer can record.

The European Commission estimates that as much as 2.5 per cent of all energy consumed by the EU is wasted through transformer losses. In line with the directive’s requirements, Zucchini Green T.HE transformers ensure a consistent reduction in energy consumption, resulting in financial savings, and a decrease of CO2 emissions released into the atmosphere.

Certifications and acceptance tests

Prior to being supplied to the customer, Legrand cast resin transformers are individually inspected and must pass the acceptance and, when necessary, type tests, if they are required at the time of order. At the end of the acceptance tests a specific inspection certificate is delivered with each transformer.
