Product Description

EV Alumina Ceramic Relay Housing / High Voltage DC Ceramic Contactor

 

1. Description:

To be considered an electrical insulator, there must be an absence of electrical conduction, with the emphasis on the word “absence.” Alumina is often the ceramic of choice as it is not only inherently non-conductive, it also possesses a high mechanical strength. However, many critical applications require much more than just these inherent material properties. They require the knowledge Ceramco engineers into all highly specialized OEM ceramic parts fulfilling these needs.

2. Feature Advantages:

1) Good advanced ceramic materials

2) High welding sealing performance

3) Satisfy various technical requests

4) Lower medium spoilage

5) Stiffness texture

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