GW8-40.5~126/630 type and GW13-40.5~126/630~1250 type can mach CJ6 motor operating machine or SJ3 mechanic operating machine.
Characteristics:
The products have property of simple structure, reliable property, wide usage, economical and long using time.
We have whole specification and can satisfy user's different parameter requirement.
Connecting terminal and the electric pole is made by casting aluminum-alloy and section bar, having the good property of high-intensity, good flowing and 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.
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.
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.
