詳細說明:
DMD-無紡布/聚酯薄膜三層複合箔
NON-WOVEN FABRIC& PET FILM COMPOSITE
絕緣級數:B級(130℃)Temperature classification:Class B(130℃)
聚酯纖維非織布/聚酯薄膜柔軟複合材料是由兩層聚酯纖維非織布,在一層聚酯薄膜的雙麵塗膠粘劑並粘貼而成的三層複合材料。具有良好的機械性能、介電性能及浸漬性能。適用於B級電機、電器中作槽間絕緣、襯墊絕緣及匝間絕緣。
Non-woven fabric/Polyester film composite is a sort of three layers combined material,which is obtained by combining non-woven fabric on each side of polyester film coated with adhesive. It has good mechanical,dielectric and impregnating properties.It is used as slot,turu,gasket insulation in class B electric machines and appliances and Y2-series motors.
