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. For the underground portion, the cable bus is installed in the encasement that is uniquely offset vented or power cooled to meet the cable high amperage requirements. The cable bus system is also suitable for high vertical rise installations when utilizing anti cable slip mechanism or technique.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
