Description: Cooper Power Systems has been manufacturing MOV disks for over two decades.
We are recognized as an industry leader in the development and production of these highly engineered ceramics.
Our arrester center, located in Olean, NY, USA includes a dedicated, high-volume disk production facility that ranks among the world’s largest for the manufacturing of MOV disks. The highly automated manufacturing process ensures uniform physical and electrical characteristics. This state-of-the-art process begins with computer-controlled mixing of the proprietary powder formulation. Once pressed and sintered into a high-density ceramic, the disk surfaces are precision ground, then coated with full face conductive electrodes using plasma deposition technology.

■ Full face metalized electrodes
■ Glass or epoxy covered outer coating (collar)
■ Meets IEC and ANSI standards
■ 100% production tested
■ ISO 9001:2000 certified
■ Available in ratings (Ur) of 3 kV, 3.33 kV, 4.5 kV and 5 kV
■ All ratings available in 5 kA and 10 kA (IEC Class 1) disks
