Zucchini cast resin transformers
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.
Products from this range form part of a wider portfolio of solutions that optimise energy efficiency in buildings.

Zucchini Green T.HE transformers
The EN 50588-1:2017 Standard requires that distribution transformers are built with the objective of ensuring high energy efficiency, while reducing the impact on the environment. Legrand is committed to contributing to sustainable technological development and fulfills the requirements of the EN 50588-1:2017 standard by introducing the Zucchini Green Transformer High Efficiency (Green T.HE).
