• Prysmian Cable 600 Volt SUPERTUF Ruggedized Low Voltage Utility Cables

    Product Details

    The amount of power transmitted matters a lot when it comes to the choice of the cable to be used. Low voltage requires certain types of cable which will not cause power or high resistance to current. Since low voltage is used in the commercial set ups, domestic appliances and even in the industrial applications, an outstanding reliability is vital. Therefore the low utility voltage cables must be competent enough to beat all odds. These cables must be resilient and also efficient in power transmission.

    Ruggedizing a cable involves reinforcing the conventional cable with a strong dielectric material around the core. This boosts the robustness of the power cables and helps it withstand the rigorous activities during installation. Ruggedized cables have an outer jacket which make them fungus and UV resistant.

    Phase Insulation
    The phase insulation of these cables has two primary layers of insulation: A clear inner layer which is made from low-density polyethylene and an outer layer which is made from a high density polyethylene. The outer layer has adaptabilities in order to be competent for the outside environment. Therefore it is made black, sunlight resistant and has high density.

    Neutral Insulation
    Neutral line acts as the return path for voltage transmission, it also has to be insulated in order to prevent unnecessary but dangerous current leakages. Therefore for low voltage transmission, the neutral path is insulated and has extruded yellow strips which help to identify. This distinction on the neutral cable helps to avoid confusions.
    For multiple assembling of cables, the phases are twisted together with one neutral.

    Installation
    Installation of these low utility voltage cables can be done by direct burial, where the cables are laid directly underground without any other material covering. This type of installation is recommended for indoor installation since in outdoor it is prone to thefts. Besides the direct burial, there is also the underground duct method where a duct is created and the voltage cables are relayed through it. This ducts tend to provide more safety to the cables.

    It is prudent to consider some few factors when doing installation, like:
    Whether that area is wet or dry, this helps to make necessary preparedness against hazards which come as a result of power leakages

    Utility secondary.
    For the underground connections, it is good to have the knowledge of the point at which to locate the service entrance before installation is carried out. For instance, the consumption rate for industrial activities cannot be compared to household consumption rate, with this knowledge one has to choose the suitable diameter of the cable to be used.

    Applications
    The ruggedized low utility voltage cable can be used in various applications as follows:
    • Industrial works
    • Mines
    • Domestic connections
    • Urban installations

    The ruggedized low utility voltage cable is often made from aluminum conductors and a dual layer polyethylene which is crossed-linked for better insulation.
