The isolation switch adopts single-phase structure, and each phase is composed of base frame, post insulator and conductive part. Post insulator can adopt composite insulator and porcelain insulation. Composite insulator can reduce the weight of the switch and ensure its insulation level.The new u-shaped contact finger and bent shaped contact head are adopted, and the contact finger and contact seat are equipped with new flow structure, insulating contact spring and other measures to ensure the product's flow capacity.The conductive part is made of high quality copper and coated with silver, which effectively reduces the resistance of the main circuit of the switch, increases the contact area of the electric shock part and reduces the contact resistance of the switch.The base is composed of 80# channel steel welded, and its service life is extended by hot galvanizing for surface treatment.The upper end of the knife blade is equipped with a fixed retractor and a self-locking device, which is used for the separation and closing of the insulated hook rod;Fastening screws are stainless steel screws, so as to avoid the occurrence of rust loosening;The rotating part of the shaft is equipped with oil-bearing, which ensures the flexible rotation and eliminates the long time stuck fault.Flexible installation: isolation switch can be installed vertically or obliquely.
