Design Features

Zirconia ceramic blocks (also known as fixed terminals or positioning ceramic parts) are key components designed for precision machinery 

and electrical equipment, and are known for their excellent mechanical properties, electrical insulation and high temperature resistance.

Precision-machined holes and locking positions

The block design incorporates multiple precision-machined holes and locking positions, ensuring accurate fixation and positioning within 

electrical equipment.

High hardness and high strength

The high hardness (Vickers hardness 11.5 GPa) and high strength (compressive strength 2000 MPa) of zirconia ceramics ensure shape and 

performance retention under high pressure and high friction conditions, enhancing equipment stability.

Superior electrical insulation

Provides superior electrical insulation performance in high-voltage environments, preventing electrical faults and ensuring safe operation.

High-temperature resistance

Good high-temperature resistance (thermal shock stability coefficient 250℃) allows the block to be used in high-temperature operating 

environments without easily being damaged.

Application areas

Electrical Equipment

Used in electrical components such as thermal protectors and terminal blocks, providing stable electrical insulation and high-temperature 

performance.
