Important Things about Power Cables

2. 5 Important Things about Power Cables that You Didn’t Know Power cables are nothing but a cluster of several cables taken together and covered with a rubber or insulated material, generally used for distributing electricity, a large volume of electricity rather to different units. Power cables stands apart from the rest in the fact that the conductors or cables within the sheath are stranded which in turn provides flexibility to the power cable itself. If you have a project at hand which requires power cables, below are quick 5 facts that you need to know before you get in touch with one of the leading and certified power cable manufacturers to finalise and customize it based on your requirement. The 5 important things are as below: 1.Copper Vs Aluminium It is generally believed that copper is a better conductor of electricity as compared to aluminium. But when it comes to transmitting electricity over long distances, the insulation material and combination of the sizes of cables also need to be considered. Moreover aluminium cables are cheaper when it comes to high voltage transmission over long distances. 2.Current Capacity of the Cable

3. Generally it is believed that the current bearing capacity of a cable is same throughout its life span. But it is not true. In fact the current capacity keeps on changing from time to time. There are several factors which contribute to the varying current bearing capacity of a power cable like the existing ground or air temperature, the actual manner in which the laying has been done and the depth at which the cables have been laid. 3.Longevity The longevity of power cables is not pretty long, as is generally expected. Quite a number of power cables are clustered together from different power cable manufacturers to produce the desired capacity of current bearing and transmission. It is very important to install the cables carefully and also use them with caution. Since these power cables are critical electrical components, it is necessary to consult from one of the leading and premium power cable manufacturers for all the necessary guidance and support in installation, usage, capacity and after sales service. The basic installation plays an important role in maintaining the lifespan of a power cable. 4.Cable Armour is used to increase tensile strength The cable armour on a power cable is not meant to protect the cable from any physical damage, as it generally seems. In fact, it is the cable armour that might increase the damage by any physical stress on the cable itself! The cable armour is generally of steel tape or steel wire which increases the tensile strength of the power cable rather than protecting them! 5.Cable Armour is not meant for preventing moisture to get into the cables The presence of cable armour does not mean that the power cables are guarded against moisture and they can be used in moist conditions! If exposed to moisture and water, these power cables will eventually decay and might cause accidents or disaster arising out of current and water conjunction!

4. Most importantly, consult the premium power cable manufacturers for a safe and secure installation and then get the project inspected by the local building inspector for faulty connection or installation gaps, based on the codes of construction rules, regulations and conduct that the engineer might have missed!
