How to Choose a Correct Standard of Cable?

As the main carrier of energy transmission, cable is widely utilized in electrical equipment, lighting circuit, household appliances and so on. The quality from the cable is straight impact the engineering quality, and also the security of life and home of consumer. There are many Cable Manufacturers in the market, and there are also numerous varieties of cable. You have to choose proper cable based on the usage of electrical energy load. You are able to find associated models and specifications in the cable specification.

Generally, whenever you select a wire and cable, except electrical wire size and electrical wire price, you should also notice some details as beneath.

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

Secondly, the choice of the standard of wire and cable. Whenever you need to make sure the specification of wire and cable, usually, you should think about heating, voltage loss, financial present density, mechanical strength and so on.

Based on the experience, for the low-voltage power line, due to its bigger load current, you should consider the section initial based on the circumstances of the heating, and then verify the voltage loss and mechanical strength. For low voltage lighting line, it features a high requirements on the voltage level, you should choose the section based on the permissive voltage loss situation, then checking the heating conditions and mechanical strength. For high voltage transmission lines, firstly, you should select section according to financial present density, and after that check the heating conditions and permit voltage loss. For high voltage overhead line, anticipate the section, heating conditions, you also should consider its mechanical strength. When the user has no experience, some professional units or people will provide some suggestions for you.

Lastly, you need to select the Cable Manufacturer. There are lots of differences between the different products supplied by different Cable Manufacturer even they've the same name or exact same size. The inner material is extremely essential for a cable. A great cable, it adopt good copper or some other higher conductivity metal, but you can't check it by yourself, so you should choose a Cable Manufacturer who has a high inspection standard and quality requirement.
