    Details
    • Provides high thermal conductivity for cooler coil performance
    • Long-term voltage endurance resists partial discharge damage and provides longer insulation life
    • Ideal for high-temperature electrical insulating applications
    • Compatible with commonly used impregnating resins and varnishes
    • Suitable for high-temperature electrical insulation applications rated up to Class 220(R)
    • Found in 3M UL Recognized Insulation Systems

    3M™ ThermaVolt Calendered Inorganic Insulating Paper provides high thermal conductivity and dielectric strength. It is ideal for dry type transformers, strip wound coils and electromagnet coils. It provides low moisture absorption, even under high humidity conditions and improves dimensional stability.

    It is suitable for Class 220(R) electrical insulation systems and 3M UL Recognized Insulation Systems may be found in UL File No. 65007. REACH Compliant and RoHS 2011/65/EU Compliant‎‎.
