To content all kinds requirements of Electrical insulation diamond dotted paper


DDP is widely used in interlayer insulation and turn insulation of oil-immersed transformers and transformers. It is made of insulating cable paper coated with rhombic thermosetting adhesive layer, baked and rolled up. When used, the coating begins to melt at a certain temperature during the drying process of coil, which produces adhesion. Easy to use, can reduce the temperature rise of transformer oil. The bonding strength of epoxy resin is enough to prevent the winding and the displacement of each layer when the coil is short-circuited, thus ensuring the long-term mechanical and electrical properties of insulation structure. With the increase of temperature, it begins to solidify again. During the coil drying process, DDP bonding solidifies the coil to form a fixed unit.
