Description of DM-DMD-DMDM Insulating Paper
DM series insulating paper is short for polyester film polyester fiber non-woven flexible composite materials. DM insulating paper is two-layer flexible composite material which is bonded by gluing polyester fiber non-woven(D) and polyester film(M); DMD insulating paper is three-layer flexible composite material which is bonded by gluing polyester fiber non-woven(D) on both sides of polyester film(M); DMDM insulating paper is four-layer flexible composite material which is composed of two-layer polyester fiber non-woven(D) and two-layer polyester film(M) overlapped alternately and glued together. DM insulating paper, DMD insulating paper, and DMDM insulating paper all have good mechanical strength and dielectric property, and higher heat resistant property. The insulation class is B class or F class.
Application of DM-DMD-DMDM Insulating Paper
DM series insulating paper is finalized insulating material of Y series motors, and can be used as insulating slot, turn-to-turn insulation and layer-to-layer insulation, pad insulation core for small and middle sized motors and turn-to-turn insulation for transformer.
