Using the Aluminum XLP USE RHH RHW
When it comes to wiring, one must choose the wires and cables with care. Sometimes people just ignore the fact that faulty wiring can lead to fire hazards which can prove lethal. Once the wiring is done, it will not be visible to the naked eye but the danger still exists and it will take hours of smoldering before a big fire breaks out. That is why the aluminum XLP USE RHH RHW cable comes in very handy for general purpose wiring for buildings as it can be used as both RHH and RHW. It can also be used as a Type USE cable and be used for direct underground burial for service entrance purposes. Where you live matters and when the climatic conditions tend to fluctuate, it is better to go in for specialized cables such as the XLP USE RHH RHW as it can be used in temperatures as high as 90°C in both wet and dry conditions. These cables are even used in transportation applications for permanent wirings which need to use 600V or less. They are also good for service entrances, branch circuit, and feeder applications, for commercial and residential purposes. Use these conductors safely in electrical metallic tubing, raceways and conduits with messenger support or as in other cases, directly buried.
To be on the safer side, the installation should be done by a professional, especially when the cable is used for direct burial. In case the insulation gets punctured, the aluminum cable is sure to corrode if the underground conditions happens to be wet and without oxygen. This will eliminate future possible hazards to a great extent and when the cables are used in harsh industrial applications, you can rest easy knowing that you have used only the very best of cables. When the installation is done by following the Local Electric Code or any other corresponding rules and regulations, the product will not get damaged or affected during installation.
Furthermore, all these cables are manufactured in accordance to UL standard 44 and in most cases you will find that they even exceed the specified standards. Moreover, you can use them for commercial and industrial purposes as the insulation is a tough cross-linked polyethylene (XLP) which comes in a black jacket. It is resistant to heat and sunlight, moisture when used as RHW, and it can even withstand dampness when used as RHH, and is also abrasion resistant. When you take a look the insulation, you will find that it is really heavy and so can be safely used underground even in wet locations.
Also take note of the allowable ampacities which are mentioned as per National Electric Code. When it is marked for 60°C, then it is 100 amperes or less when marked for 14 - 1 AWG conductors. When the conductors are marked larger than 1 AWG, then it can be over 100 amperes at 75°C. Conductors have to be UL listed and there has to be no compromise on that if you are keen on optimal performance and durability.
