Transformer Rubberised Cork Sheet
TRANSFORMER RUBBERISED CORK SHEET
One of the most popular material used in the domestic market, that is highly suitable for power transformers and heavy engineering applications. Transformer rubberised cork sheet is made from fine imported cork granules that provides excellent oil, heat and ozone resistant properties. It's excellent compression set and side-flow properties control lateral spread tendency of an ordinary cork sheet and is therefore, best suited for outdoor transformers. We provide rubberised sheet size of 915mm x 915mm, 915mm x 610mm and 1040mm x 1040mm (1000mm x 1000mm) with the thickness as per customer request.
