Power
Transformers

ELSPRO transformers in housings made of high-quality, robust solid rubber are an investment in safe working with Power. The durable ELSPRO solid rubber housings of all product series are manufactured using the press and vulcanization process. The action of heat and pressure makes rubber mechanically resilient and largely resistant to chemical, aging and weathering influences. ELSPRO transformers are available in numerous housing sizes. The assembly and design is carried out according to customer requirements in compliance with the applicable standards and directives.

Safety transformers and isolating transformers according to VDE 0570/DIN EN 61558
