11 MPHusky CABLE BUS Engineered to Build Powerful Reputations For more information or to order, call or visit mphusky.com

12 MPHusky Page 9 MPHusky CABLE BUS Construction MPHusky has over 45 years experience coordinating our cable bus power distribution systems with many types of applications. Our cable bus consists of a fully enclosed & ventilated metal housing and utilizes fully rated factory insulated power cables supported with nonmagnetic support blocks. MPHusky s cable support blocks are designed and manufactured to last the life of the system and are utilized to maintain individual cable spacing, as well as ensure short circuit bracing of a minimum 100KA RMS Symmetrical Amps. Our factory welded aluminum alloy enclosure provides a completely protected bus system and is provided in custom lengths, with each housing section sized to fit the specific installation. 90% of our systems utilize 6063 T6 aluminum, but we also provide stainless steel and Hot Dipped Galvanized After Fabrication Steel housings when required. And our extensive custom fabrication capabilities ensure that we can manufacture nearly any special housing, connection or accessory to manage all of your difficult coordination challenges. Each cable bus system includes all necessary power cable, equipment connections, flanges, wall entrance seals, fire stops, elbows, offsets, terminal lugs, termination kits and miscellaneous parts. Insulated neutral phase conductors and ground conductors (bare, tin plated, or insulated) are also provided as an option. A complete set of matchmarked layout drawings show the location of each section and all accessories. We utilize only the highest quality products, including: Structural 6063 T6 aluminum for standard housing along with stainless steel tie bolts for our cable support blocks, Burndy twohole long barrel compression lugs, Nelson fire stops, Raychem or 3M Termination Kits, and high quality conductors that include General, Kerite, Okonite, Pirelli, etc.. Reliability After decades of superior performance, many engineers, buyers and owners choose MPHusky Cable Bus over nonsegregated phase bus duct, conduit & wire, and cable in tray due to it s higher reliability, lowest cost, greater flexibility and maintenancefree construction. Our cable bus design provides superior reliability by utilizing high quality, continuous run power cables (no splices) that are completely protected in a ventilated metal housing. And since our system design is not affected by moisture and is ventilated for outdoor and indoor applications, it does not require For more information or to order, call or visit mphusky.com

13 Page 10 MPHusky heater strips or filter breathers that competitive technologies require to try to keep moisture out of their system. Our systems are tested and fieldproven in some of the most extreme environments and weather conditions including Paper Mills, Fossil Fuel Burning Facilities, Chemical Plants, Mining Facilities, Heavy Salt Environments, Cold Areas (North Canada, Alaska), Hot Areas (Saudi Arabia) and Tropical Areas (Puerto Rico and Nigeria). And our extensive experience and knowledge with the widest range of applications and environments, along with our superior engineering and design, provides you with a real advantage in reliability and proof of design. The bottom line is when you choose MPHusky CABLE BUS, you ensure you will have the most reliable power distribution system, whether compared to competing technologies or other cable bus manufacturers. Cost Savings/Ease of Installation Typical cost savings realized with MPHusky Cable Bus over competitive technologies such as NonSegregated Phase Bus Duct, Conduit & Wire, and Cable in Tray range from 15% to 50%+. And our optimal design, which includes our exclusive corrugated and ventilated top and bottom housing, as well as our continuous parallel conductors (no interleaving) throughout the entire run of housing, can save you 10% 25% over other cable bus systems installed costs. Our engineered design achieves a free air rating of the power cables; the competition often has to derate cables, leading to higher conductor costs of up to 40%. Combine this lower upfront system cost with the easiest installation, and MPHusky s Cable Bus System is the most costeffective power distribution system available. Easy installation is achieved through our matchmarked layout drawings and single phasing arrangement throughout the entire cable bus run. Most of our competitors use multiple phasing arrangements, which requires interleaving cables inside the bus housing, creating expensive and confusing installations. MPHusky Cable Bus does not interleave or transpose cables in the bus housing. Another advantage our cable bus housing only weighs 5 7 lbs./ft., therefore 12 sections can easily be handled by two men without the aid of heavy equipment such as cranes, booms or lifts; and our cable bus housing is designed and manufactured with the bottom cable support block factory installed, saving you more on installation costs. Flexibility MPHusky s Cable Bus systems are flexible and adaptable to the many unexpected circumstances that occur during construction. Every size and rating of cable bus provided is supplied, free of charge, with up to 5% extra cable as well as one spare length of housing including cover, cable support blocks and hardware. This enables the installer to adjust our system in the field to discrepancies or differences between engineering drawings and actual field construction, with little or no delay of the project. And our compact design and radius bends allows our system to maneuver around and fit in the lowest clearance applications. For more information or to order, call or visit mphusky.com

14 MPHusky Page 11 Cable Bus Short Circuit Bracing Cable bus support blocks are spaced every 18 in vertical applications and 3 in horizontal applications. This ensures proper cable arrangement and spacing, while providing short circuit bracing of 100kA RMS Symmetrical (actual short circuit test certification available). Our support blocks are made of select hard rock maple treated for preservation and are constructed to last for the life of the system. For tropical environments, we also provide HDPE (High Density Polyethylene) support blocks. Bottom support blocks come factory preassembled in the bottom section of the housing assembly and corresponding layers of support blocks are then fastened with stainless steel bolts. Engineered System MPHusky Cable Bus is a completely engineered system. You supply the power routing and termination details and we do the rest. MPHusky s experienced and knowledgeable engineers layout and design a custom system that is specific to your requirements. Our exclusive Inductive Reactance Program is used to design optimum phasing arrangements that minimize losses and imbalance in the system. The Inductive Reactance Calculations cover impedance values, voltage drop and power loss, which we provide to you as part of our system. We also offer inhouse lab testing for current and special applications, as well as custom fabrication capabilities that can accommodate nearly any coordination challenge. As part of our engineering services, we provide short circuit calculations and actual shortcircuit test results, and we also offer heat rise calculations with actual heat rise test results. And we recognize the value of our engineering service goes beyond our design and drawings. Thus, we provide field engineering services prior to and during engineering and construction, as well as during and after project startup. We rely on building longterm, trustworthy relationships, and thus nothing less than 100% customer satisfaction at all stages of the project is acceptable. Equipment Coordination MPHusky has extensive custom fabrication capabilities, ensuring that no matter what coordination challenges exist, if the physical space exists to maintain clearances, we can fit our cable bus system to whatever needs to be connected. We have built anything from simple box extensions for transformers to 4 feet square by 10 feet tall custom generator termination boxes. MPHusky has terminated to transformers manufactured by most manufacturers including, Carte, Northern, ABB, GE and others. We have made custom boxes to make cable terminations where no provisions for such existed, such as generator stepup transformers with 15kV cover mounted bushings intended for overhead substation line termination. We have also coordinated with most major switchgear and MCC manufacturers, from 480V though 35kV, including ArcResistant switchgear. Switchgear Manufacturers include ABB, Allen Bradley, Cutler Hammer, Siemens, GE and others. For more information or to order, call or visit mphusky.com
