Overview

Superior 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 arrangments in conjuncture with the ventilated enclosure allows cables to maintain the 'free air rating', resulting in a more effecient, 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, the Superior Cable Bus does not have to be precisely aligned with the bus bars in the switchgears or transformers which is essential in electrical busduct / busway installations. Superior Cable Bus systems are designed for both indoor and outdoor installations and do not require heater strips or forced air cooling for the system . The key five benefits of Superior Cable Bus systems are:

Presentation

Lowest Cost Power Distribution

• Superior Cable Bus is the most cost effective power feeder. In electrical applications over 1,000 amperes, Superior Cable Bus costs less than any other power feeder systems.
• Superior Cable Bus Sections are light and its bottom cable support blocks are factory pre-installed making its installation easily handled by two men.
• Cable Bus Systems are pre-cut to fit specific location, requiring no special heavy erection equipment.
• Superior Cable Bus uses free air rated power cables that are installed in a ventilated enclosure and cable spacing is maintained by support blocks. Because less conductor carries the full rated current (maximum ampacity in accordance with ICEA (Insulated Cable Engineers Association) listings for 90 degrees C rated conductors, wasted power is eliminated resulting in a lower operating cost of our Superior Cable Bus System.

Adaptability of Cable Bus

• Flexible and adaptable: Superior cable Bus System can be easily adjusted according to the unforeseen dimensional changes during installation as cable bus sections can be routed around any field obstruction or misplacement of equipment and can be cut-to-fit onsite as required.
• Removable top covers for ease of power cable installation and addition of other circuits or power cables.
• The cable bus systems do not have to be precisely aligned with the bus bars in the switchgears or transformers which are essential in the bus bar systems.
• The layout comes complete with match marked drawings to sections. Thus it facilitates easy field erection.

Safety

• All welded rigid construction.
• Due to the robust structure and unique design of Superior Cable Bus, power cables are protected from damage caused by falling ice and other foreign objects. Moreover, the structure is so strong that in an emergency situation, workman can walk across the superior bus system without causing any structural damage.
• 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 Superior Cable Bus system has excellent protection against adverse atmospheres and is used in both indoor and outdoor applications.

Reliability

• Top and bottom covers of Superior Cable Bus are ventilated for optimum free air rating so de-rating is not normally required and power cables run cooler.
• Each system's phase arrangement of Superior Cable Bus is verified by inductive reactance calculations to ensure a more balance load.
• 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 Superior Cable Bus System reliability.

Custom Fabrication

• 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.
• We have knowledgeable and experienced technical staff to design a cable bus system from scratch or work with existing prints for industries like medical, marine, electronics, construction, petrochemical, power plants, etc.
• In some instances, clients only provide the details of the equipment termination and power route and we will do the detailed engineering design of the most economical and suitable cable bus electrical system for the installation.
• Our main goal is to achieve 100% client satisfaction by providing our clients with field engineering services in addition to our design expertise.
