In the world of electrical insulation, the choice of material can mean the difference between reliable operation and catastrophic failure—especially in high-voltage motors and generators operating under extreme conditions. The Polyimide Film Mica Tape from Hanyao represents the premium tier of mica-based insulation products. By replacing polyester film with high-performance polyimide film, this tape achieves insulation levels of Class H (180°C) and even Class C (220°C), far exceeding the Class F rating of conventional polyester mica tapes. With excellent dielectric strength, mechanical toughness, and chemical resistance, it is the material of choice for demanding applications in aerospace, defense, and heavy industry. This article examines its technical specifications, key advantages, and the applications where it delivers unmatched reliability.

1、 Electric motor new energy field (core use) New energy flat wire motor, servo motor, traction motor: wrapped with copper wire winding, insulated between turns, isolated from high voltage, and resistant to friction and damage of enameled wire;

Polyester Mica Tape is a fire-resistant insulation composite material composed of mica sheet as the insulation core, polyester film (PET) as the reinforcing substrate, and adhesive composite. It is the core insulation material for motors, cables, and transformers. The core is divided into four categories: insulation, fire-resistant, protective, and process adaptation

For a long time, the high-end thermally upgraded insulation paper market has been monopolized by imported brands, resulting in high procurement costs, long delivery cycles and insufficient supply flexibility for transformer manufacturers. With the continuous upgrading of domestic power equipment manufacturing standards, high-performance localized insulation materials have become an inevitable trend. Thermally Upgraded Kraft Paper launched by Hanyao breaks the technical barrier of imported products, providing a cost-effective and stable alternative solution for power and distribution transformer insulation.

Polyester Heat Shrinking Tape is divided into two categories: electrical insulation braided heat shrinkable tape and PET film heat shrinkable wrapping tape. It is applied in fields such as electrical, new energy vehicles, packaging, aerospace, medical equipment, HVAC refrigeration, etc

The structural and operational reliability of oil-immersed transformers depends entirely on the integrity of their internal insulation networks. When high-voltage transformers operate under continuous thermal and electrical stresses, internal conductors require flexible, high-dielectric barriers that can bend without collapsing. We analyzes how the Electrical Insulation Crepe Paper Tube, manufactured by Hanyao, serves as a foundational component in modern solid insulation systems. We examine its raw material chemistry, mechanical behavior under physical bending, chemical interactions with transformer oil, and specific manufacturing parameters to demonstrate how it maximizes transformer operational lifespans.
