Detailed Product Description

EV HVDC Contactor Advanced Technical Ceramics Al2O3 Aluminium Oxide Ceramics

1. Description:

HVDC is a method of transmitting electrical energy across long or extremely long distances using an overhead transmission line or an underground cable or submarine cables.It will be economically eye-catching over traditional AC transmission lines.

2. Feature Advantages:

1) Good advanced ceramic materials

2) High welding sealing performance

3) High hardness and high density

4) Low thermal conductivity

5) Chemical inertness

6) Lower medium spoilage
