Preformed Slot Wedges made from Premium DMD are economical, convenient and reliable insulation options for the slots of low and medium voltage electric motors. Unlike most grades of DMD on the market, Associated Gaskets’ premium grade of DMD, from which these wedges are formed, is able to withstand the rigours of Class H, or 180ºC, electrical applications.
AG offers our Preformed Slot Wedges made from Premium DMD in two main styles, square and round. All are manufactured from 100% Premium DMD, are light blue in colour, and offer good shape retention and easy fitting.
