Patent number: 6726857Abstract: The present invention comprises a mixture of hydrocarbons having a well-defined chemical composition that is suitable for use as a dielectric coolant in electrical equipment in general, and specifically in transformers. The dielectric coolants of the present invention are particularly suited for use in sealed, non-vented transformers, and have improved performance characteristics, including decreased degradation of the paper insulating layers, as well as a greater degree of safety and environmental acceptability. The present dielectric coolants comprise relatively pure blends of compounds selected from the group consisting of aromatic hydrocarbons, polyalphaolefins, polyol esters, and natural vegetable oils, along with additives to improve pour point, increase stability and reduce oxidation rate.Type: GrantFiled: November 25, 2002Date of Patent: April 27, 2004Assignee: Cooper Industries, Inc.Inventors: Gary L.

Patent number: 6682681Abstract: An encapsulated transformer includes a transformer coil assembly, a rigid core insert having an upstanding portion positioned within the hollow interior of the core and a base portion on which the core rests, and a thermoplastic rubber jacket that completely surrounds the transformer coil assembly and is bonded to the base portion of the core insert to provide a completely waterproof encapsulated transformer which is impervious to liquid and gasses that could be detrimental to the performance of the transformer. A method for producing such an encapsulated transformer includes placing a rigid core insert in a mold cavity of a mold, and positioning a transformer coil assembly in the mold cavity so that the transformer coil assembly rests on the core insert. Thermoplastic rubber is then injected into the mold cavity to completely encapsulate the transformer coil assembly in a jacket of thermoplastic rubber.Type: GrantFiled: June 7, 1995Date of Patent: January 27, 2004Assignee: Cooper Industries, Inc.Inventors: William A.

Patent number: 6504103Abstract: An elbow terminator has a socket in which an electrical probe is disposed. The terminator is insertable onto an electrical bushing such that a tongue of the bushing is received in the socket of the terminator, and the probe of the terminator is electrically coupled to a contact sleeve disposed within the tongue. A latching mechanism produces positive latching between the tongue and socket when the tongue has been inserted to a predescribed depth within the socket. In order to enable an operator to visually observe that the tongue has been inserted to the prescribed depth, the bushing carries a color band which becomes completely disposed (invisible) in the socket when positive latching occurs. Alternatively, the bushing can be provided with gauge tabs which become aligned with a witness line formed on the terminator when positive latching occurs.Type: GrantFiled: March 20, 1997Date of Patent: January 7, 2003Assignee: Cooper Industries, Inc.Inventors: Andrew Edgar Meyer, Todd Kim Knapp, Frank John Muench
