Product Description
Characteristics
Good Structure and mechanical property. Using V type 90° Rotate twirl way, it has advantages of the simple structure, stable power balance, reliable operative way and small covering area.
Whole specifications and we can satisfy different clients' parameter requirement.
Terminal block and conductive rod is made by casting aluminum alloy and aluminum alloy section, having the advantage of high-intensity, good flowing and good anti-corrosion.
In the galvanic circle, the section is the combination structure made by screw fix linking, having the good property of stable flowing, high reliability, simple change way and convenient adding volume way.
In the galvanic circle, the contact and finger is made by T2Y pure copper tap whose connecting part is coated by 30μ M silver.
Finger spring is made by the stainless steel and its design is the inside hiding and outside press structure which is convenient for testing and changing
The bearing has changed from the bevel rear structure to the Universal connecting rod drive structure, having the advantage of simple structure, high intensity, convenient operation way and safety enough.
Bearing block is made by high-intensity casting steel (disposed by hot zinc coating), the height can be adjusted and have the function of damping.
Have different install way such as front install, side install, back install and leak 25° Install and so on, adapting to different station entering line ways.
All the operating rod and linking rod are supplied by manufacturer, which is convenient for loading, adjusting and testing.
It can be supplied as a whole above the ground according to user's requirement.
