Power Cable Assemblies

 

Custom Options

Liquid-tight conduit, size, color, shielding, and insulation are just a few of the many important considerations when selecting power cables. Our focus is to help you develop the right cabling solution for your specific environment.

Single or Multiple Circuit Cables (closed nipple or daisy chain) Space under the Data Center floor is always difficult to allocate and manage. When you consider the number of “line-powered” devices to be provisioned, you should also consider installing our Multiple Circuit Cables (MCC). Our MCC’s allow you to run up to three (3) circuits per cable to reduce the number of conduit runs and save space under the Data Center floor. The benefit of installing our Daisy-Chain cables is similar to our MCCs. You can use a single circuit and conduit to save space under the Data Center floor by feeding multiple receptacles.

Cables built to exact specifications

Always use the correct length of cables, allowing for some slack at the end for device movement and final fitting.  Too much cable can create airflow problems under a raised floor. 

When hundreds of power and communication cables run under a raised floor, even a few extra feet of coiled cable can create air dam problems.  Excess cables take up valuable space creating airflow problems that negatively impact cooling efficiencies and energy consumption.  With PDU Cables, we manufacture each power cable assembly to your exact specifications. 

 

Cable tails are cut to an 8’ standard length.  Longer tails are available when wiring to tall RPP units or connecting to a cable trough. 

To PDU Cables, building power cable assemblies to meet our customers exacting specifications goes beyond lengths and receptacle types, and includes the use of specified manufacturers' components.  While our experience allows us to recommend the highest quality components possible, unlike electricians, electrical contractors or other cable manufacturers, we carry multiple manufacturers' components in stock ready to substitute to meet your specific preferences.

Every application and configuration is unique, at PDU Cables your cables are manufactured to those exacting specifications. 

Eleven liquid-tight conduit colors in stock - identify and ensure utilization of dual corded servers.

Most data centers have adopted the use of redundant power sources and a good way to organize those dual power feeds is to match liquid tight conduit by color for each power source.  For added convenience and improved cable management, PDU Cables offers eleven colors of conduit allowing data centers to have unique colors for each primary and redundant PDU/RPP unit.

Painted faceplates and receptacle boxes in eleven colors to match the liquid-tight conduit colors in stock.

A perfect way to extend your color schemes used to manage redundant power sources all the way to the receptacle end.  Even if you are forced to use Greenfield, Metal Clad Cable or Flexible Metal Conduit (RWS or RWA) you can still use colors to manage primary and redundant power sources.  PDU Cables will paint your branch circuit power whips any of the same colors we offer for liquid-tight conduit.

Matched Circuit Breakers - Plug-in and bolt-in style circuit breakers instock for your convenience

With each cable purchase PDU Cables can provide a circuit breaker matched to the cable and your main breaker, giving you one less thing to worry about.  PDU Cables stocks a full line of both plug-in and bolt-in style circuit breakers, including Square D, GE and Cutler-Hammer. 

A Variety of Mounting Options

Proper airflow in and around the data center is critical to optimal operating efficiencies.  Keep under floor power cables in the hot aisle running parallel to the computer room air conditioner (CRAC) unit airflow.  Consider elevating mounting positions for the receptacles to help protect against possible pooling water and cable air dams, allowing for better air flow and improved CRAC unit efficiency. 

Mounting hardware can be custom designed and added to your cables so they can be secured to strut or raised-floor pedestals. This allows easier access to the receptacles and keeps the cables off the floor eliminating the risk of water damage.

PDU Cables offers a variety of options to facilitate elevated mounting positions including pedestal clamps attached to the back of the box, mounting bolts through the back of the box for the receptacle to be attached to the uni-strut, and mounting ears. 

Proper mounting of cables isn't limited to under floor; PDU Cables can also show you some mounting options for overhead drop down applications.
