Patent number: 8117739Abstract: An electrical module assembly used in a surge arrester is manufactured by wrapping an electrical module assembly including at least one metal oxide varistor (MOV) disk to which a reinforcing structure including a pre-impregnated epoxy/glass-fiber composite has been applied with shrink film and compacting the wrapped electrical module assembly by heating the shrink film such that the shrink film shrinks and applies a radially compressive force to the electrical module assembly. The wrapped electrical module assembly then is cured at a temperature at which the shrink film no longer applies a compressive force.Type: GrantFiled: January 23, 2004Date of Patent: February 21, 2012Assignee: Cooper Technologies CompanyInventors: Michael M. Ramarge, Alan P. Yerges, David P. Bailey, Roger S. Perkins

Patent number: 6847514Abstract: A surge arrester includes a stack of components having at least one varistor. Each component has end faces, at least one of which is mechanically bonded to an end face of another component such that the combined components of the stack define a single, monolithic structure that serves as both an electrically-active element and a mechanical support element of the surge arrester. The surge arrester also includes an insulative housing surrounding the stack of components. The stack of components is capable of withstanding current pulses having magnitudes of 65 kA and durations of {fraction (4/10)} microseconds without significant degradation in operating performance of the stack of components.Type: GrantFiled: December 20, 2002Date of Patent: January 25, 2005Assignee: Cooper Industries, Inc.Inventors: Michael M. Ramarge, David P. Bailey, Roger S. Perkins, Thomas C. Hartman, Alan P. Yerges, Ramon Puyane, David R. Miller

Patent number: 6757963Abstract: A surface of a first ceramic component is joined to a surface of a second ceramic component using a silver-based composition. The silver-based composition is a mixture of silver metal and a metal oxide and the metal in the metal oxide is a metal other than silver. The silver-based composition is applied to the surface of the first ceramic component and to the surface of the second ceramic component. The silver-based composition applied to the first ceramic component is contacted to the silver-based composition applied to the second ceramic component. The surfaces of the first and second ceramic components are heated to melt the applied silver-based compositions. The surfaces of the first and second ceramic components are cooled to form a bond between the first and second ceramic components.Type: GrantFiled: January 23, 2002Date of Patent: July 6, 2004Assignee: McGraw-Edison CompanyInventors: Alan M. Meier, David R. Miller, Kevin R. Dickson, Roger S. Perkins, Michael M. Ramarge

Patent number: 6483685Abstract: An electrically-conductive and mechanically-compliant joint is formed between a pair of electrical components. The joint is positioned between a lower face of a first electrical component and an upper face of a second electrical component. The Young's modulus of the joint is less than approximately half that of the Young's modulus of the electrical components.Type: GrantFiled: May 25, 2000Date of Patent: November 19, 2002Assignee: McGraw Edison CompanyInventors: Michael M.
