A698 Aramid Insulation Pressboard

A698

Aramid Insulation pressboard

A698 is a high-density (from 1.10 to 1.20 g/cm³) aramid pressboard featuring a smooth, dense surface. It's characterized by superior dimensional stability and high electrical properties, even at elevated temperatures.

Its excellent mechanical strength ensure that it can withstand the immense pressures within the equipment, providing lasting support and maintaining the integrity of the entire assembly, ideal for manufacturing dimensionally stable components such as transformer spacers, support bars, and end insulation plates.

Aratech® A698 Core Features

A698 ensures operational continuity in extreme environments by delivering superior compressive strength, thermal endurance, and chemical resistance to withstand the most demanding conditions.

Stable Dielectric Performance

Functions as a reliable electrical insulator, preventing shorts and dielectric breakdown between components. Its stable dielectric constant ensures predictable, consistent performance across a range of operational temperatures.

Exceptional Thermal Stability

Maintains its critical mechanical and electrical properties during continuous operation at elevated temperatures. This resistance to thermal degradation ensures a long and reliable service life for the insulated components.

Excellent Compressive Strength

Offers superior resistance to deformation under high compressive loads, a critical feature for load-bearing spacers. This high strength is maintained even at peak operating temperatures, ensuring structural integrity.

Superior Dimensional Stability

Exhibits minimal expansion or contraction when exposed to changes in temperature and humidity. This ensures that component tolerances are maintained and winding assemblies remain tight and secure over time.

Proven Chemical Resistance

Demonstrates excellent compatibility with and resistance to a wide range of chemicals, including transformer oils and varnishes. This prevents material degradation and ensures long-term system integrity in various fluid-filled applications.

Inherent Flame Retardancy

Composed of aramid fibers that are inherently flame-retardant and will not sustain combustion in air. The material is self-extinguishing, providing a critical safety factor in case of electrical faults or overloads.
