Abstract: how to distinguish the pros and cons of wire and cable information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Wire and cable as the main carrier of power transmission, which are widely used in electrical equipment, lighting, home appliances, etc. , its quality directly affects the engineering quality and the life and property safety of consumers. There are many varieties of wire in the market, to the root. More flow meter manufacturers choose model price quote you are welcome to inquire, here is how to distinguish the pros and cons of wire and cable article details. Wire and cable as the main carrier of power transmission, which are widely used in electrical equipment, lighting, home appliances, etc. , its quality directly affects the engineering quality and the life and property safety of consumers. There are many varieties of wire in the market, according to their own power load to use appropriate wires. Wire on the market sell some cheap some more expensive, some people tend to be cheaper, but cheap wire, often have a lot of short he shows that the performance, may bring us a lot of potential safety hazard. Wire production technology content is not high, raw material also does not have the too big difference, if too many cheap, or cut corners, or number does not give enough. That how to don't sign? I signed several easy for everyone to say other methods: 1, to look at the packaging, national standard of wire tend to do better, neat, holding up a sense of quality. 2, to open the packaging to look at the inside of the wire, 1 gb of wire. 5 '- 6 square wire requirements is too thick ( Insulation thickness) Is 0. 7 mm, too thick is a mark, and the corresponding his inner core is sure enough, line pulling skin you can force, it is not easy to tear is generally is gb 3, burn it, leave within 5 s after go out, have certain flame retardant function for the line. 4, filling, filling material ( Copper) The higher brightness copper, the better, and luminosity, luster, no administrative levels. The national standard requirements must use oxygen free copper inner core. Not mark such as black copper rod, there may be a hazard. 5, the thickness of the inner core countries have certain requirements, but not very strict. Not wrong a lot, however, is just a little bit small, see not to come out is commonly used in error. 6, length, and the state must dozen meters, is not mandatory but there are a lot of manufacturer also dozen meters, the meters are not necessarily national standard, but the general national standard generally have no dozen meters. The underlying dozen meters that is only a means. 7, the provisions of the state power lines must have certain identity, zui big there will be no more than 500 mm under the same type identification, above the average product of trademark, name of manufacturer, standards, etc. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
