CABLE BUS MP HUSKY Cable Bus Systems are engineered and manufactured for superior reliability as well as to utilize less conductive material, providing signiicant savings versus non-segregated phase bus duct, conduit and wire, and other electrical feeders. As copper prices have continued to remain at historically high levels, the savings clients realize are even greater and more important. No matter how you look at it, MP HUSKY Cable Bus outperforms other electrical busways in reliability, cost and lexibility. See for yourself why more owners, engineers and buyers choose MP HUSKY Cable Bus...

Safe • MP HUSKY Cable Bus is an all welded rigid construction. • Contractors are free of shock hazards - no exposed bus elements, only insulated conductors used. Factory Fabricated - All Welded • Ventilated design prevents entry of foreign objects. • Bottom cable support block is...

CABLE BUSBUS CABLE Technical Information Selection of the proper Cable Bus system must be undertaken with care to assure that it compliments the design of the overall electrical power system. Shielding Shielding is used on power cables to conine the dielectric ield of the conductor to the cable insulation. Shielded Power Cables are used in Cable Bus for applications above 2500 volts and when any of the following conditions exist: 1. Where cables are subject to soot or other heavy deposits that may form paths to ground. 2. Where electrostatic discharge can efect nearby computerized control...

Technical Information MP HUSKY Cable Bus is designed for balance of conductors within a phase (intra-phase) and balance between the phases (inter-phase). Many phasing arrangements will provide inter-phase balance of currents due to the load impedance, but the majority of these phasing arrangements provide intra-phase current imbalance. System Balance Cable Bus is a power distribution system using insulated single conductor power cables with support blocks that maintain cable spacing. Each phase consists of one or more cables connected in parallel. The complete assembly is enclosed in a...

CABLE BUSBUS CABLE Technical Information Short Circuit Testing Since Cable Bus is often used for main feeder connections, (e.g. substation, generator or transformer to switchgear, load centers and high voltage machines), the available short circuit current will be that of the utility or generator supply through the transformers. In some cases, the Cable Bus feeds large motors and the motor contribution to short circuit must also be considered. Numerous tables are available listing motor contributions for various operating conditions. The Cable Bus systems were tested on a 600 volt, 3 phase,...

Technical Information Grounding A Cable Bus system must aford protection to life and property against faults caused by electrical disturbances. Lightning, electrical system failures, as well as failures in the system connected equipment all constitute possible fault hazard locations. For this reason, all metal enclosures of the system, as well as non-current carrying or neutral conductors should be tied together and reduced to a common potential. This includes the structural steel of the building, water, steam and gas piping. There are two distinct divisions to the system and equipment...
