For your home or office to function, you need electricity. And to utilize and transmit electricity and power to all your appliances, gadgets, and other technology, you need the support of electrical cables.
Electrical cables are the basic components of any electrical system, be it industrial, commercial, and residential installations, high power cables, or electrical appliances. With the number of electrical cables available in the market, the precise electrical cable you need for your application depends on several factors, including the application purpose, voltage, capacity, the electrical cable prices, the expected conditions, etc.
You can find a great range of electrical cables at RS Components.
So, what do you need to know before purchasing electrical cables? Let us take a look.
The conductivity of an electrical cable plays an important role in its performance. Out of the commonly used electrical cables, copper is a better conductor of electricity. So, for your home or office, you can opt for copper wires that offer the best conductance ratio. However, if the application needs super-high voltage to be carried for a longer distance, Aluminium is the preferred and economical choice. For instance, aluminum is used extensively in long-distance high electrical power cables.
The current capacity of a wire varies with load
The current capacity of the electrical wire changes with the load of the current. It also changes with the depth at which the cables have been laid or with the ground or the air temperature. Therefore, it is vital to choose an electrical cable that is of good quality and has high endurance with any such factors.
Electrical cable sheaths are not used to prevent moisture to seep in
The protective insulation sheath around an electrical cable is not expected to protect the cable from the water. For that reason, if the protective sheaths are damaged, exposing your electrical cables to moisture or water, may lead to short circuits.
The conditions in which the electrical cable is used will determine the type of jacket that is ideal for it. The conditions include climatic conditions, possible exposure to liquids from other sources, impact or other possible strain, and normal tear and wear.
Electrical cable sheaths are not used to protect electrical cables from physical damage
The protective sheath that is used on the electrical cable is not intended to protect the cable against any chances of physical impact. On the other hand, if an electrical cable is exposed to a form of physical stress, there are chances that the damage to the cable caused by the impact is likely to be intensified by the outer sheath.
The protective sheath or insulation jacket on an electrical cable is made up of steel wires that are meant to increase the tensile strength of the cables and not to protect the cables from physical impact.
Electrical cables are available in a wide range of cores, voltage, and current ratings as well as different sheathing materials and different electrical cable prices. Choose the correct electrical cable for your application or intended use to ensure a safe installation and durable performance.
