A697 Aramid Insulation Pressboard

A697

Aramid Insulation pressboard

UL Certification No.: E509207

Aratech® A697 is a medium-density aramid pressboard with a density range of 0.70 to 1.00 g/cm³, the thicknesses ranges from 1.0mm to 4.0mm. it characterized by a textured mesh surface. A697 features with excellent bending and forming capabilities, making it suitable for forming complex geometries like transformer insulation cylinders, slots, and angle rings.

Its key characteristic is its high affinity for oil saturation, ensuring complete impregnation for optimal performance within liquid-immersed transformers

The Aramid Solution for Complex Structural Insulation

Aratech® A697 Core Performance Features

A697 delivers unprecedented design freedom, allowing you to create complex components that are simultaneously flexible in form and uncompromising in their thermal, dielectric, and fire-retardant integrity.

Stable Dielectric Properties

Provides a reliable electrical barrier, safeguarding against dielectric breakdown in the demanding oil-filled environments of modern transformers.

Exceptional Bending Formability

Its structure allows for excellent bending and forming capabilities, enabling the precise creation of complex geometric components.

good impregnability

The textured surface and controlled porosity facilitate rapid and thorough saturation with oils and resins, creating a unified insulating structure.

Outstanding Thermal Stability

Engineered to maintain its mechanical and electrical integrity at high continuous operating temperatures, ensuring long-term system reliability.

Broad Chemical Resistance

Demonstrates exceptional resilience against degradation from a wide range of common industrial solvents, oils, and other chemicals.

Excellent Flame Retardancy

The inherent aramid fiber composition is self-extinguishing, enhancing the overall safety and fire protection of high-value electrical assets.
