Power cable comes in a variety of shapes and sizes, and can look complicated to the layman. These cables can be single-conductor, multi-conductor, as well as industrial strength or for personal use. Each type of power cable has its own advantages, which make them suitable for certain types of applications.
A power cable is categorized in three classes, 1) high voltage (for applications requiring load greater than 40,000V), 2) medium voltage (for applications requiring load between 6000V and 36,000V) and 3) low voltage (for applications requiring load below 1000V). These cables are used for feeders and other heavy machinery, along with branch circuits in electrical utility, commercial and industrial applications.
Single-conductor power cable is used in various applications such as stage lighting, locomotives, DLO and for welding purposes. Each single-conductor cable, depending upon its use, has a different rating for amps, voltage, flexibility and insulation, each having a different price-level.
There are many multi-conductor cables; extensions cords, Type G-GC, Type W, SOOW and portable cords, each encased a rubber jacket for insulation. These cables are safe and flexible and when additional flexibility is required, there is a multi-conductor cable available for this need. The SOOW multi-conductor cable is similar to the extension cord (before the plugs are attached) and is generally used to supply power generators and tools in industries.
The least-expensive power cable of this group is the welding cable. Welding cable has a rubber jacket and flexible copper fibers and is rated to 600V. DLO cable also has the rubber jacket, is rated to 2000V and has tinned copper fibers. The DLO can carry more power and therefore has a higher corresponding price.
Remember, when installing power cable, it is recommended that you consult with your electrician. And when it is time to purchase your cable, some helpful hints include knowing the operating temperature, amperage, voltage, outer diameter (cable diameter + insulation jacket).
