Using Cables Such as the 3/0-3 EPR CPE
It is not the brick and mortar that make up a working industry but the wires, and cables that are installed. You will find that no industry will run if there are no wires to connect it to the main power grid. You need cables even for underwater oil refineries and other hazardous industrial applications. It is not only the responsibility of the design and electrical engineers to get it going, but also up to everyone who works in such places. Everyone should know about the types of cables used in such conditions and the reasons why these cables are preferred.
Generally engineers do not use the cables that are labeled as residential general purpose cables, but instead, choose specialized cables that can take a lot of potentially hazardous effects on it. They have to be resistant to water, oil, gas, chemicals and acids to name a few factors. They have to have tough insulation to protect the heart of the cable, namely, the conductors. The main idea is that there should be no disturbance or fluctuations in the signal or current carrying capacities of the cables. You will have to find the right cable for each kind of application and it is imperative that you do not generalize the use of cables, even though most cables can be used for a lot of purposes.
Most of the time, the cables will come with specifications which are suitable for a particular kind of work. To make things simpler, let us discuss the 3/0-3 EPR CPE cable. It is a tray cable that can be used for underground burial as well as for use in structures like cable trays. They are used in the floors of industries and can also be used for wet locations. It comes with a flame retardant insulation, which is the FR-EPR ethylene-propylene rubber, made in accordance with ICEA requirements. Moreover, the individual conductors go through a painstaking checkup to see whether they can stand up to tough environments and they are only approved when they pass the UL requirements.
The conductors are also made only with approved Class B copper stranded and tinned wires, and the whole assembly is covered with tape for further protection. Make sure that the cable meets all your wiring requirements or else ask your electrician for alternatives. Care should be taken to choose the right kind of wires, and try not to compromise on the quality as it ensures safety and long life of the entire wiring system, as well as the individual cables. Copper cables, such as the 3/0-3 EPR CPE, will also minimize corrosion and possible damage from overload.
Check out the amperage that flows through your cable and whether it will be ideal for your system. You will have to calculate whether the cables can handle the amount of load that you are eventually going to put on it. So it is better to go in for cables that exceed your requirements rather than low-end ones. This will save you the trouble of replacing or redoing it in the near future.
