With the continuous development of society, our life is inseparable electricity, the premise of using various electrical appliances electronic products is the power cord. Every home needs a lot of power cords to build the electrical network to power all the devices. Without power cords, our daily lives would be a mess. Precisely because of its importance, when buying, be sure to pay attention to the standard.Guangxi cable

What standard should be selected for wire cable? First, formal. Try to buy an official manufacturer, the selected product must have the certification mark trademark, specification, factory number, voltage, etc. Second, packaging. Conventional manufacturers will wrap the wire once with PVC clear film during the wire wrapping process, then use a serpentine belt to wrap it one more time to ensure that the product is easily damaged during shipping. weight. The weight of the power box is within the specified range. Generally speaking, the weight of a two-core rubber sheathed wire with a cross-sectional area of 0.75mm2 is 200 meters, between 12.3kg 12.8kg. Guangxi wire cable

In addition to these criteria, when purchasing a power cord, you can cut a section of the insulation to see if the core is in the middle of the insulation. Power cords with eccentric cores can cause weakness to prevent easy breakdown.

Guangxi wire cable is a certificate issued to the manufacturer after the product has passed the test of the EU VDE certification body.

In layman's terms, it refers to a square number. This is a common phenomenon in the market. For example, the line is marked as 0.75 square, the actual measurement is 0.673 square. Such square numbers are disqualified. This requires asking the supplier for the copper wire conductor construction. The conductor structure of 0.75 square is 24/0.2, that is, 24 copper wires with a diameter of 0.2, each square wire has its conductor structure, so you must know it when buying. To avoid unnecessary troubles caused by insufficient copper, common symptoms include shortened lifespan, hot wires, short circuits caused by resistance.

There are many types of copper wires used for electrical wires, including brass, copper, red copper, copper-clad aluminum, tinned copper, etc., are usually used in rubber wires cables (both red copper red copper refer to industrial pure copper). Copper), there are other impurities in brass, which cannot meet the standard of industrial pure copper, copper-clad aluminum is inferior. Copper wire is an important part of electrical wiring, so be sure to ask before buying.Guangxi cable manufacturer
