Description of isolator switch

GW16-72.5~245 semi pantograph disconnector Characteristics:

It has the property of compact structure, advanced, clean appearance, beauty, Reliable property, economical.

After tripping, the vertical contact don't take up the space, especially adapt to the site that the entering line and exit line vertical different height.
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.

Adapt to site's different laying way: One Line laying, 45° Laying, 135° Laying and so on
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
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.
