| Distribution Class Surge Arresters
Cooper Power Systems offers the largest, most economical selection for low voltage, distribution, riser pole, intermediate, and station surge arresters for overhead and underground applications in the industry.
VariGAP® Design Technology
Would you like to extend the life of your underground cable beyond what you though possible?
Do you have old or sensitive cable that needs extra protection from voltage stresses to lengthen its service life?
Would you like to know how you can about extend the life of your transformers by simply choosing a different arrester?
Do you have ungrounded sections on your distribution system that are problematic for arresters?
If you have answered yes to any of these questions, Cooper's VariGAP distribution arresters are for you. VariGAP arresters offer unbeatable equipment protection and arrester relaibility.
With up to 30% lower discharge voltages compared to equally rated gapless MOV arresters, equipment life can be extended due to the reduced stresses placed upon them. VariGAP arresters can survive much higher magnitude and longer temporary overvoltages (TOV's) than equally rated gapless MOV arresters. As such, areas prone to high voltage rises (undergrounded systems in particular) can be reliably protected with VariGAP arresters. With its supreme TOV withstandability, VariGAP arresters are the most reliable arrester on the market today.
Other Arrester Classes and Designs
VariGAP (gapped MOV) and VariSTAR® (gapless MOV) designs are available for overhead distribution system protection in both porcelain or silicone rubber housings. For underground distribution application needs, Cooper Power Systems offers both VariGAP and standard gapless MOV elbow and parking stand arresters.
Cooper has a large line of low voltage arresters for a wide range of application needs from transformer secondary to home or business service entrances to inside the home. Other low voltage products protect lighting, motors, irrigation wells, traffic lights, railroad crossing gates, and any other number of low voltage applications.
Cooper also offers a full line of Intermediate and Station Class arresters in either silicone rubber or porcelain housings.
MOV Technology
Cooper Power Systems has been manufacturing its own line of MOV disks for over two decades. We are recognized as an industry leader in the development and production of these hightly engineered ceramics.
Making our own MOV disks allows us to closely monitor production and eliminate any unsatisfactorily performing product before
it ever gets into an arrester. This also allows us to experiment to find ways to make an extremely good product even better.
Continual quality improvement is a driving force within Cooper Power Systems and, as such, our ceramics engineers do look to improve the overall quality and durability of our MOV disks.
