Features and Applications:
Dispensing DMD is a special modified epoxy resin Ling grid-like evenly coated on the DMD soft composite material from the new electrical insulation materials. In use, the coating begins to melt at a certain temperature, producing adhesion and curing with increasing temperature so that the adjacent layers of the windings are reliably bonded into a fixed unit with sufficient adhesive strength to prevent Layer displacement, so as to ensure long-term insulation of mechanical and electrical properties. In addition, the resin coating point distribution, to ensure that the oil immersion and gas discharge, can effectively avoid the corona and partial discharge, so that the reliability of the insulation structure is guaranteed.
Detection standard reference:
GB/T 5591.2-2002 Standard Test Methods for Electrical Insulating Flexible Composites
GB/T 1408.1-2006 Standard Test Method for Breakdown Voltage of Solid Insulating Materials
