I-6630 (DMD) i-polyester film polyester fiber non-woven soft composite material ukumelana nokushisa iklasi B iyisigqi esithambile esiyingqimba ezintathu, eyenziwe ngendwangu engalukiwe ye-polyester, ifilimu ye-polyester, ukwakheka kwe-polyester non-woven (DMD), i ingcina esetshenziswayo ayinayo i-asidi, imelana nokushisa, inezinto ezinhle zemishini nezikagesi, indwangu ye-polyester engalukiwe inamandla okukhangisa, ingakwazi ukumunca inhlaka lapho ifakwe. Isetshenziselwa ukufakwa kwe-inter-slot kanye ne-inter-phase insulation motors low-voltage motors , noma isetshenziswe njenge-interlayer insulation in transformers, ukuqina kwezinto ezibonakalayo kukhulu, futhi kulungele izinqubo zemishini ezingaxhunyiwe ku-inthanethi.
6630 (DMD) Iphepha le-insulating lekilasi B kufanele ligcinwe endaweni engenawo umoya, eyomile futhi ehlanzekile yegumbi lokushisa (ngaphansi kuka-40°C). Ngesikhathi sokuthutha nokugcinwa, ukunakwa kufanele kukhokhwe emlilweni, umswakama, ukucindezela nokuvikelwa kwelanga. Isikhathi sokugcina ekamelweni lokushisa yizinyanga ezingu-12, futhi sisengazanywa ngemva kokudlula izidingo zobuchwepheshe zesikhathi sokugcina.
