Central Plain Cable--The Five Steps Let You Learn How to Buy and use Electrical Cable and 4 gauge battery wire

Wire and cable , especially PVC insulated cable (commonly known as plastic wire ) is the main carrier of power transmission , the use of very wide , especially in the " city network , rural power network transformation into the family line and home decoration indoor line is very large amount of raw material for production of polyvinyl chloride insulated wire and h07rn f cable products mainly copper wire , aluminum wire and PVC insulation material (commonly known as plastic ) , therefore , the quality of their qualities will directly affect the PVC insulated cable products . The face of many enterprises cables products , consumers in the purchase and use should pay attention to the following points :

First of all , should be trustworthy , good reputation of the product .

Second , pay attention to product identification , to prevent counterfeit products . General PVC insulated cable product labels should be marked with the name and address , rated voltage , specifications , length and so on , especially in the cable wire should be printed with continuous marks including factory name , type , rated voltage , single line spacing should be not greater than 200 mm , sheath line marker spacing should be less than 500 mm .

Tird , buy PVC insulated twin and earth cable products before , first of all to consider its good use . The general situation are that through the power of the electric appliance , the current of the wire is calculated and the size of the wire is selected according to the current . It's best to consult with an experienced and professional electrician , because the section carrying capacity and conductor wire , wire and materials (aluminum or copper ) , method of laying type , (surface or through pipe etc . ) and ambient temperature and so on , there are many factors affecting the complicated calculation .

Fourth , You can look at the cross section of wire , copper (aluminum ) core should be in the middle and the plastic layer thickness should be uniform . Then you can try the plastic strip wire end . If it is easy to strip , there may be plastic strength is not enough . The stripping of copper (aluminum ) core after that , can look at the copper (aluminum ) core materials , under normal circumstances the surface should be with metallic luster , if the white surface blackening of copper or aluminum surface is metal oxide . It is best not to sell . If possible , you can try to burn it . If the general lighter can burn , and no flame self extinguishing or self extinguishing time is longer . The 2/0 welding cable is not burning , so the wires do not buy .

Finally , in the use of plastic wire must correct wiring . Usually best by professional electrical wiring , their connection , pay attention to plastic wire joint should be firmly connected , not simply taped together , so electricity joint easy to heat , will lead to serious fire !
