Electrical Steatite Ceramic Terminal Block Heat Resistant Ceramic Connector
Steatite Ceramic
Steatite is an inorganic material based on natural raw materials consisting predominantly of magnesium silicate. It is marked by a high heat resistance, resistance to leakage current and dielectric strength. It is recommended as an insulation material in electrical engineering.
Features & Advantages
1. Good dielectric strength
2. Heat resistance and form stability up to 1000°C
3. High mechanical strength
4. Non-combustible
5. Resistant to UV radiation
Advantages of High Quality Electric Ceramic Connector
Anti aging, fire protection and heat-resistance , good insulation property, strong mechnical property, good steady property. It can be used in different enviroment, also can meet mechnical device connection of severe working temperature etc.
Application of Industrial Electric Ceramic Connector
Electric Ceramic Connector is widely used in high temperature enviroment, kinds of connection terminal space of severe demand.
