01
Advantages of conductors
The main conductive arm adopts aluminum alloy profile, which has high strength, light quality, large heat dissipation area and good anticorrosion performance.
-
02
Advantages of static contact
The moving contact has reliable contact with the contact finger, small operating force, no impact on the fixed insulators at both ends, and the main contact has self-cleaning ability. The contact spring is made of stainless steel and has an insulating pad, and the spring does not rust or shunt.
