Robert R. Pawluk has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10141731
    Abstract: A cable bus system for the mounting and positioning of high amperature, from low to high voltage electrical power cables transmitting polyphase electrical current. The cable bus system included a ventilated enclosure used to protect electrical cables mounted therein. The enclosure is provided with multiple modular cable trays which are bolted together in a stacked arrangement to form a single multi-level cable raceway. The enclosure is further provided with ventilated top and bottom covers which are secured respectively to the top and bottom of the uppermost and bottom most cable trays to define the enclosed metal circuit. The cable bus system is capable of transmitting the same highest allowable “free air” cable amperature in both above and underground installations, effectively improving the transmission of electrical power from one end to the other end, in installations where a transition of electrical power from below ground to above ground is either necessary or economically preferable.

  • Patent number: 4956523
    Abstract: An armoured electric cable having integral tensile members to provide additional tensile strength. The tensile members are embedded in an inner PVC jacket which securely grips the central insulated conductors over which it is extruded. The jacket is, in turn, securely gripped by an armour cover formed of a steel strip which is wound helically around the jacket and bites into longitudinal ridges on the jacket. The armour coating has an undulating shape and is covered by an outer PVC jacket which is extruded over it. Thus, in the vertical position much of the weight of the insulated conductors, inner and outer PVC jackets and armour coating can be supported by the tensile members without producing dangerous longitudinal slippage or creepage between them.
