Product Description

Insulated Alumina Ceramic Housing / Stud For 400A 24V HVDC Relay

 

1. Description:

A comparison of the technological, economic, public policy and environmental factors of HVDC and HVAC interregional transmission. Considering the financial and technical aspect the DC long transmission line is better than AC long transmission line.

 

2. Feature Advantages:

1) High compressive strength.

2) High hardness and high density

3) Low thermal conductivity

4) Chemical inertness

5) Good wear resistance

6) High Fracture toughness
