The Challenge

>Transformerboard and insulation paper are the two highest-volume insulation categories in transformer production, and the two where batch-to-batch consistency in density and dielectric strength matters most. Qualifying a new supplier on both at once requires the supplier’s documentation to be right the first time.

The SIDA Solution

SIDA supplied transformerboard / pressboard and insulation paper manufactured to IEC 60641-3-1 and ISO 9001 requirements, each shipment accompanied by a mill test report and batch-level traceability. Lead times are measured in weeks, and the customer can add further categories from SIDA’s 17-category insulation range through the same supply channel.
