Product Description
Electric three phase isolator switch with motor
1.Simple Structure, reliable property, wide usage, economical and long-time life.
2.Complete specification and satisfy user's different parameters requirements.
3.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
4.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.
5.In the galvanic circle, the contact and finger is made by T2Y pure copper tap whose connecting part is coated by 30μ M silver.
6.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.
7.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.
8.All the operating rod and linking rod are supplied by manufacturer, which is convenient for loading, adjusting and testing.
9.Can be supplied as a whole above the ground according to user's requirement.
