    The main use of a conduit, otherwise known as a duct, is to give a clear and protected route for any given cable. Improvements in the cable technologies and the costs that come with repairing of sensitive cable materials have led to the preference of protective conduit to direct burial. Those in the construction industry use polythene conduit as it offers mechanical protection to materials and protection from chemicals and moisture. It is basically for these reasons that PowrServ brought to the market the PowrServ CDC Underground Distribution Secondary Combined Duct & Cable Secondary Cable Installed in Extruded High-Density Polyethylene Duct.

    Determining a PowrServ CDC Combined Duct and Cable
    In the event you are installing a cable and would like to determine whether what you have is a PowrServ CDC Combined Duct and Cable simply confirm that the cable does have a duct. It should have a black conduit that is made of HDPE- high density polyethylene material. Your cable should as well be able to coil. Conduit materials that are flexible such as the one used in the PowrServ CDC require enough compressive strength so that they can resist compressive pressure that are as a result of external loading. The polyethylene EPEC-A conduit used has been tested and is in line with the NEMA standard TC7.

    Features that make the cable to perform well: 
    When it comes to cables you should know that weight is a crucial matter and should never be sidelined. The PowrServ CDC cable is light enabling one to easily move it about during installations.
    • The cable and duct is very easy to install thanks to the fact that it has been pre-installed. This in turn makes the
       costs related with installations to significantly come down.
    • As earlier mentioned installations cables ought to be flexible. This cable and duct sure is flexible so that when in
       places with bends and corners, it will not only fit well but also give you an easy time during installation.
    • The duct is highly resistant to destruction and other kinds of pressures. The HDPE material making the conduit
       provides high impact resistance and protection from sharp and hard items.

    Applications
    If you are thinking of underground cable distributions, then this is the cable to go for. It is just perfect for underground secondary distribution systems. Why should you waste your economical resources pulling down previously used cables? Forget all that and go with this economical alternative. It gives installation in short lengths of conduit.
    Cost is something you certainly want to cut down. The PowrServ CDC Combined Duct and Cable ensure that money intended for labor remains in your pocket. You can now forget about costs related with ground disruptions during replacement as this cable and duct can be easily pulled out without having to disrupt the ground.
    The PowrServ CDC Combined Duct and Cable sure is great in terms of efficiency as well as economically. Hopefully this information has been eye opening. Feel free to share with us any further detail.
