EV Alumina Ceramic Relay Housing / High Voltage DC Ceramic Contactor


1. Description:

High voltage devices require insulators not only to contain the electric current, but also to not interfere with it. Such applications for which manufactures OEM ceramic parts include: high voltage spark arrestors and spark plug gap insulators.One device of note produces a 300kV electrical spark. A spark so strong, it finds any defect in the insulator, leading to the corona effect, or corona discharge, or worse, a conduction path other than the one intended for the current. Recalling the word “absence” mentioned earlier, such defects negate the intended purpose of the insulator. When encountered in a high voltage application.

2. Feature Advantages:

1) Low thermal conductivity

2) Chemical inertness

3) Good wear resistance

4) High Fracture toughness

5) Stiffness texture

6) Widely apply for automotive ceramic sensor , ceramic heater ,electric heating
