is the most cost effective power feeder. In electrical applications over 1000 Amps, our cable bus systems costs less than any other power feeder systems.
can be easily adjusted according to the unforeseen dimensional changes during installation. Cable bus sections can be routed around any field obstruction or misplacement of equipment, and can be cut-to-fit on site as required.
All welded rigid construction. High pressure splice joints provide an excellent path to ground. Workmen are free of shock hazards, no exposed bus elements - only insulated power cables are used.
The system's short circuit capacity has been designed to over 100,000 RMS symmetrical amperes. Support Blocks restrain the power cable through the entire system. Fully insulated power cables are used and the only conductor connections are at the equipment terminations. Since terminations are the cause of most electrical failures, the minimal conductor connections increases the reliability of
.
We have an excellent and versatile manufacturing facility with an expert engineering and design team. We have the capability to customize a design to suit the specific requirements of any electrical installation.

Our cable bus systems utilize fully continuous cable conductors mounted on nonmagnetic, non-metallic support blocks within a CSA certified ventilated enclosure. Since conductors are continuous, there are no power losses from intermediate splices or connections, and the conductor arrangements in conjuncture with the ventilated enclosure allows cables to maintain the 'free air rating', resulting in a more efficient, reliable power distribution system.
Our cable bus systems have a lower impedance and lower voltage drop as compared to other power distribution systems because of only implementing power cables that are properly phased, spaced and secured in a pre-engineered system.
The use of parallel power cables, combined with the free air rating, allows cable bus to operate fully and efficiently with less conductor material than that called for with other types of power feeder systems. Additionally,
does not have to be precisely aligned with the bus bars in the switchgear or transformers which is essential in electrical busduct / busway installations.
systems are designed for both indoor and outdoor installations and do not require heater strips or forced air cooling for the system
