Design Features

Zirconia ceramic head caps (also known as ceramic insulators or thermal insulation sleeves) are high-performance ceramic components 

specifically designed for high-temperature electrical equipment, aiming to provide superior insulation and thermal protection.

Optimized Shape Design

Precise shape design, including a smooth surface and appropriate dimensions, accommodates various electrical interfaces, ensuring 

excellent insulation and mechanical stability.

High Mechanical Properties

The high hardness (Vickers hardness 11.5 GPa) and high compressive strength (2000 MPa) of zirconia allow the ceramic cap to maintain 

its shape and performance even under high pressure and high temperature environments.

Excellent Corrosion Resistance and High Temperature Resistance

Suitable for use in chemical handling and extreme temperatures, preventing corrosion and material degradation, suitable for harsh 

environments.

Electrical Insulation

Excellent electrical insulation properties, suitable for high-voltage environments, preventing current leakage and electrical accidents.

Application areas

Electrical Equipment

Used as insulation protection in transformers, motors, and high-voltage switches to ensure the safe operation of electrical equipment.

Air Purification Systems

As an electrical insulation component in air purifiers, protecting electrical components from high temperatures and dust.

Machinery in High-Temperature Environments

Used in furnaces, heat treatment equipment, and other machinery requiring thermal insulation to prevent heat loss and protect sensitive 

components.

Specialty Applications

Used in scientific research and military equipment for high-precision applications requiring extreme insulation and heat resistance.

The high-performance design of zirconia ceramic caps ensures reliability and efficiency in modern industrial applications, especially in 

high-temperature environments where electrical safety and performance are critical. Their high durability and electrical insulation properties make them particularly important in applications requiring extreme protection, making them ideal for modern electrical equipment and 

high-temperature machinery.
