3M™ CeQUIN I Inorganic Insulating Paper is an inorganic-based paper for high-temperature electrical insulating applications. Qualified for use in electrical insulation systems up to Class 220® per UL 1446 and IEC Std. 60085; CSA Component Acceptance at 220 C. Applications include ground and layer insulation in dry-type transformers, as well as interwinding insulation in strip-wound coils and electromagnet coils; pole insulation in traction motors; wire-wrap for UL Recognized Class 250 C appliance wires; and spiral-wrapped core tubes. The high inorganic content in CeQUIN I papers (up to 90 percent) offers excellent thermal and dielectric stability, as well as high thermal conductivity, long-term voltage endurance (up to three times that of calendered aramid papers), and low moisture absorption. CeQUIN I papers are compatible with commonly used impregnating varnishes and resins, and are easily impregnated, further enhancing thermal conductivity and coil bonding characteristics. 3M™ Innovative Paper Technologies UL Recognized Insulation Systems (File No. 65007) may be found on UL’s Electrical Insulation Systems database at http.//database.ul.com/systems/.
