AMA insulation paper is a type of high-performance flexible composite insulation material, composed of polyester film (M) sandwiched between two layers of aramid insulation paper (A) — hence the name A-M-A structure.
It combines the excellent thermal resistance and mechanical strength of aramid paper with the dielectric strength of polyester film, making it widely used in medium- and high-temperature electrical equipment.

Dry-Type Transformers
Used for interlayer insulation, end insulation, spacers, and gaskets in coils.
Offers excellent thermal resistance (Class F 155℃ or higher) and dielectric strength, ensuring long-term operational safety.
Electric Motors
Applied as slot insulation, slot liners, phase insulation, and end wrapping insulation.
Especially suitable for high-temperature motors, inverter-driven motors, traction motors, and servo motors.
Oil-Immersed Transformers
Used as insulating pads and oil duct spacers.
The AMA composite structure provides good oil resistance and dimensional stability.
Reactors and Instrument Transformers
Used for interlayer insulation and support within windings.
Can withstand high mechanical stress and temperature rise.
Switchgear and Control Cabinets
Applied in insulating partitions, shields, and terminal insulators.
Improves overall dielectric performance and safety of the equipment.
Appliances and Electronic Components
Used for miniature transformers, inductors, relays, and solenoids.
Ensures stable insulation and heat resistance under continuous operation.
New Energy and Battery Systems
Serves as insulating liners or separators inside battery modules, preventing short circuits and local discharge.
