How you can Choose a Correct Regular of Cable?

As the main carrier of power transmission, cable is extensively utilized in electrical equipment, lighting circuit, household appliances and so on. The high quality from the cable is straight impact the engineering high quality, and the safety of life and property of customer. There are many Cable Producers in the marketplace, and you will find also many varieties of cable. You have to choose correct cable based on the usage of electrical energy load. You can discover related models and specifications in the cable specification.

Generally, when you choose a wire and cable, except electrical wire size and electrical wire price, you need to also notice some details as below.

First of all, you have to choose right wire and cable kinds. At this time, you need to think about the purpose, the laying circumstances and security, for example: based on the various utilizes, you can select power cable, aerial insulated cable and manage cable; based on the different laying conditions, you can choose general plastic insulated cable, Screened Control Cable, steel tape armoured cable, Armoured Energy Cable, anti-corrosion cable and so on; based on the security requirements, you are able to choose the flame retardant cable, halogen totally free flame retardant cable, fire cable, etc..

Secondly, the choice of the regular of wire and cable. Whenever you need to ensure the specification of wire and cable, generally, you should consider heating, voltage loss, financial present density, mechanical strength and so on.

Based on the experience, for the low-voltage energy line, because of its bigger load current, you need to think about the section first according to the circumstances from the heating, and after that check the voltage loss and mechanical strength. For low voltage lighting line, it has a higher requirements on the voltage level, you should select the section based on the permissive voltage loss condition, then checking the heating conditions and mechanical strength. For high voltage transmission lines, firstly, you should select section according to economic current density, and after that check the heating circumstances and permit voltage loss. For higher voltage overhead line, anticipate the section, heating conditions, you also should think about its mechanical strength. If the user has no experience, some expert units or individuals will provide some ideas for you.

Finally, you need to choose the Cable Manufacturer. There are many differences in between the various goods supplied by different Cable Manufacturer even they have the same name or exact same size. The inner material is very important to get a cable. A great cable, it adopt good copper or some other high conductivity metal, but you cannot verify it by yourself, so you should select a Cable Manufacturer who features a higher inspection standard and high quality requirement.
