AMA Insulation Paper

 

AMA Insulation paper is a soft composite material, a three-layer insulation paper made of polyester film coated with adhesive and bonded to two sides of aramid paper. Imported H-grade glue is used, which combines the excellent high temperature resistance of aramid paper at 220℃, good mechanical toughness and good dielectric strength of polyester film. It is widely used in electrical equipment, suitable for slot insulation, turn insulation and pad insulation of motors.
Store in a dry and clean room with a room temperature below 40℃, away from fire, heating and direct sunlight. The storage period is 12 months. If it exceeds the storage period, it can still be used if it passes the inspection according to technical standards.

4/Q：What is the name of the paper used in transformer insulation?

A：The above describes the color and thickness of three types of insulating paper commonly used in transformers, such as electrical kraft paper, NOMEX insulating paper and NMN insulating paper.

 

5/Q：What material do transformers use to alternately insulate and cool the windings?

A：Large oil-filled power transformers use windings wrapped with insulating paper, which is impregnated with oil during assembly of the transformer. Oil-filled transformers use highly refined mineral oil to insulate and cool the windings and core.
