Cooper Power Systems is the worlds largest manufacturer of Pole Mounted Auto Reclosers with a pedigree at their Kyle manufacturing plant in South Milwaukee going back over 50 years. One of the first manufacturers to use vacuum interrupting techniques, this has been at the heart of their reclosers for more than 20 years.
The latest axial magnetic vacuum interrupters were developed and patented at the Kyle plant. Coopers oil insulated, vacuum interrupting reclosers have served the industry safely and reliably and continue to be the preferred option in many parts of the world. The use of SF6 as either an interrupting or an insulating medium was rejected by Cooper due to the anticipated problems with by-products, loss of gas and eventual legislation against the gas due to its greenhouse classification.

With Coopers ‘in house’ vacuum and epoxy moulding capability the natural development was to the solid encapsulation of a vacuum bottle. This required great expertise when you consider the electrical and thermal stresses involved in a fault clearing device. The successful combination of this idea with magnetic actuation has led to the NOVA recloser which is ‘State of the Art’ in this field.

Whether your requirement is for simple protection, fully automated reconfiguration or remote control, Cooper has the necessary control package, experience and product reliability to give you peace of mind.
