How to Choose a Correct Standard of Cable?

Because the main carrier of energy transmission, cable is extensively utilized in electrical gear, lighting circuit, household appliances and so on. The quality of the cable is straight affect the engineering quality, and the security of life and property of consumer. There are lots of Cable Producers within the market, and you will find also numerous varieties of cable. You need to select correct cable based on the use of electrical energy load. You can discover related models and specifications in the cable specification.

Generally, when you select a wire and cable, except electrical wire size and electrical wire cost, you need to also notice some details as beneath.

To begin with, you need to select correct wire and cable types. At this time, you should think about the purpose, the laying conditions and safety, for instance: according to the different uses, you can select energy cable, aerial insulated cable and control cable; according to the various laying conditions, you are able to select common plastic insulated cable, Screened Manage Cable, steel tape armoured cable, Armoured Power Cable, anti-corrosion cable and so on; based on the security requirements, you are able to select the flame retardant cable, halogen totally free flame retardant cable, fire cable, and so on..

Secondly, the option of the regular of wire and cable. When you have to make sure the specification of wire and cable, generally, you need to consider heating, voltage loss, economic present density, mechanical strength and so on.

Based on the experience, for the low-voltage power line, due to its larger load current, you should think about the section initial according to the circumstances from the heating, and then check the voltage loss and mechanical strength. For low voltage lighting line, it features a higher requirements on the voltage level, you should select the section according to the permissive voltage loss situation, then checking the heating circumstances and mechanical strength. For higher voltage transmission lines, firstly, you need to select section according to financial present density, and then verify the heating circumstances and permit voltage loss. For high voltage overhead line, expect the section, heating conditions, you also ought to think about its mechanical strength. When the user has no experience, some expert units or individuals will offer some suggestions for you personally.

Lastly, you need to choose the Cable Manufacturer. There are lots of differences in between the various products supplied by various Cable Manufacturer even they have exactly the same name or same size. The inner material is extremely important to get a cable. A good cable, it adopt great copper or some other high conductivity metal, but you cannot verify it by your self, so you need to choose a Cable Manufacturer who features a high inspection standard and high quality requirement.
