Mica Washer

Mica washers are flat, ring-shaped components used primarily for electrical insulation and thermal management in high-temperature and high-voltage applications. They are valued for their excellent dielectric strength and heat resistance, which can be up to 1000°C depending on the mica type.

Key Properties

Mica washers possess a unique combination of electrical, thermal, and mechanical properties that make them ideal for demanding industrial applications.

High Dielectric Strength

They offer superior electrical insulating properties, effectively preventing current leakage and electrical breakdown.

Heat Resistance

Mica is flame retardant and can withstand temperatures up to 250°C

Mechanical Strength

Mica washers have good mechanical strength, are tough, and can be precision-punched into various shapes and sizes.

Applications

Used in motor control gear, switchgears, transformers, motors, and generators for reliable insulation.
