The most rigorous applications call for proven insulating and protecting products. 3M™ Flexible Insulation products are performance engineered to perform under some of the toughest conditions.
As the demands on electrical components increase, insulating materials must meet more hostile conditions.
3M offers a wide range of Flexible Insulation products that have been refined, tested and proven in the field – from use as high-temperature electrical insulation in transformers, motors and generators to use as flame barriers in lighting and household appliances.
3M™ Liquid-Filled Transformer Insulation meets the high performance insulation requirements for new high-temperature, liquid-filled distribution transformer design with excellent thermal stability up to thermal class 155°C.
The 3M™ Flame Barrier FRB products are electrical flame barriers that provide the very high UL 94 5VA flame rating, excellent arc and track resistance, good dielectric strength and good thermal performance to safely contain electrical hazards for applications such as LED luminaires.
M™ CeQUIN Inorganic Insulating Papers and Laminates feature superior varnish absorption in a range from 5mils (.79mm) to 60 mils (1.5mm) thick. Designed for high temperature applications such as dry-type transformers and traction motors, it is qualified for use in electrical insulation systems through Class 220(R).
3M™ CeQUINBORD CGA Inorganic Insulating Boards feature low moisture absorption in sheets up to 3/8” (9.5mm) thick. Suitable for use in electrical insulation systems through Class 220(R), it can be used in dry-type transformers and other high temperature applications.
Take the high-temperature capabilities of inorganic materials, and combine them with the high mechanical strength of organic fiber. The result: 3MTM TufQUIN Hybrid Insulating Laminates which provide toughness and maintain dielectric strength for applications including motors, generators and dry-type transformers. Excellent for use in electrical insulation systems through Class 200(N).
High efficiency electrical equipment produces heat. With 3M™ThermaVolt Calendered Inorganic Insulating Laminates, you can dissipate the heat with good thermal conductivity while maintaining dielectric characteristics. ThermaVolt AR Electrical Insulation Paper offers this excellent thermal conductivity with even greater mechanical protection. Both are ideal for dry-type transformers with electrical insulation systems rated through Class 220(R).
3M™ DMD180 High-Performance Flexible Laminates are tough, and can be formed to meet the requirements for motors, generators and other equipment with electrical insulation systems rated through Class 180(H).
