CentrayCentrayCentray (Center Rail)

A center rail cable tray for an integrated wire management system.

Centray simplifies the support and routing of power and telecom/teledata

cabling. A single hanger rod is used at each support point, which makes

installation easier by reducing support requirements and eliminating the

need to pull cable through the “trapeze” supports. Very few fittings

and variations, as well as single bolt connections, add to the

simplicity and lowest cost installation of this system.

• Cables can be laid on both sides

• Rungs come already attached transversely through either the

top or bottom of the center tubular rail • 50% less labor • 75% less components and hardware than other trays

• Each rung is securely staked to the center rail in four places with 4 rung types—Top Rung,

Bottom Rung, Dual- Width Rung, and Wall Rack

• Rung tips are chamfered to provide a smooth end and limit the opportunity for cable

damage (optional end caps available)

• Meets NEMA 12B and 12C

MPHusky CABLE BUS Engineered to Build Powerful Reputations


Page 9

MPHusky

MPHusky CABLE BUS ConstructionMPHusky CABLE BUS ConstructionMPHusky 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 non-magnetic

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 match-marked 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 two-hole long barrel

compression lugs, Nelson fire stops, Raychem or 3M Termination Kits, and high quality conductors that

include General, Kerite, Okonite, Pirelli, etc..

ReliabilityReliabilityReliability After decades of superior performance, many engineers, buyers and

owners choose MPHusky Cable Bus over non-segregated phase bus duct,

conduit & wire, and cable in tray due to it’s higher reliability, lowest cost,

greater flexibility and maintenance-free 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


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 field-proven 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 InstallationCost Savings/Ease of InstallationCost Savings/Ease of Installation Typical cost savings realized with MPHusky Cable Bus over competitive

technologies such as Non-Segregated 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

de-rate cables, leading to higher conductor costs of up to 40%. Combine this lower up-front system cost

with the easiest installation, and MPHusky’s Cable Bus System is the most cost-effective power

distribution system available. Easy installation is achieved through our match-marked 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.

FlexibilityFlexibilityFlexibility 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.

MPHusky

Cable Bus Short Circuit BracingCable Bus Short Circuit BracingCable Bus Short Circuit Bracing Cable bus support blocks are spaced every 18” in vertical applications and 36” 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 pre-assembled in the bottom section of the housing assembly and

corresponding layers of support blocks are then fastened with stainless steel bolts.

Engineered SystemEngineered SystemEngineered 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 in-house 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 short-circuit 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 start-up. We rely on building

long-term, trustworthy relationships, and thus nothing less than 100% customer satisfaction at all stages

of the project is acceptable.

Equipment CoordinationEquipment CoordinationEquipment 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 step-up 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 Arc-Resistant switchgear. Switchgear Manufacturers include ABB, Allen Bradley,

Cutler Hammer, Siemens, GE and others.

AMPACITY COMPARISONS

This table illustrates the greater current carrying capacity of CABLE BUS as com-

pared to alternate methods. The increased capacity is due to free air ventilation

and maintained cable spacing. (Based on NEC & ICEA Tables at 90˚ C in 40˚ Ambient)

For higher amperage & voltage requirements up to 8,000A and 69KV, please contact the factory.

Please note: Additional derivatives may apply based on the amount of interlocked armored cables used and the

spacing between conductors.
