Design Features

Zirconia ceramic terminal blocks (also known as terminal blocks) are key components designed for modern electrical equipment and 

industrial applications, and are widely used due to their excellent mechanical properties, electrical insulation and high temperature resistance.

Complex Geometry and Hole Design

The terminal blocks feature precision-machined holes and locking mechanisms designed for accurate fixation and positioning of 

electrical connections, adapting to various installation requirements.

High Hardness and High Strength

The high hardness (Vickers hardness 11.5 GPa) and high strength (flexural strength 800 MPa) of zirconia ceramics ensure that they 

maintain their shape and performance under high pressure and high friction conditions.

Superior Electrical Insulation Properties

Excellent electrical insulation properties ensure safe operation in high-voltage environments, preventing electrical failures.

High Temperature Resistance

Zirconium ceramics remain stable in high-temperature environments (withstanding thermal shock up to 250°C), making them suitable for 

high-temperature industrial applications.

Application areas

Electrical Equipment

Used in electrical equipment requiring high reliability and electrical insulation, such as transformers, motor control systems, and 

distribution boxes.

Industrial Automation

Used in industrial automation equipment, including sensor interfaces and high-precision positioning components in control systems.

High-Temperature Applications

Suitable for heat treatment equipment, furnace temperature monitoring systems, and other electrical components requiring 

high-temperature resistance.

Specialty Equipment

Also used in equipment for chemical processing and harsh environments due to its corrosion resistance and high strength.

Zirconia ceramic terminal blocks offer reliable solutions for modern electrical and industrial applications, particularly in high-voltage, 

high-temperature, and environments requiring precise electrical safety, thanks to their superior design and materials. Their excellent 

mechanical and thermal properties ensure long-term stability and efficient operation, making them ideal for high-performance electrical 

connection solutions.
