UL electronic wire purchase and correct installation method

Ul electronic line can be divided into three series of UL standard, 3C standard and VDE standard. Generally, the AWG is the UL standard. The square of the section is mostly 3C standard or VDE standard, and our domestic ul electronic line. The manufacturer is mainly based on the two standards of 3C and UL.

    1. When selecting ul electronic wire, try to choose products that meet the standard requirements. Wire and cable are national mandatory safety certification products in China. All production enterprises must obtain the 3C mark certified by China Electrotechnical Products Certification Committee, and on the products and certificates. Labeled with 3C certification.

    Second, in terms of performance and specifications, it is not an easy task to choose the one that suits your requirements in a complex and tens of thousands of ul electronic lines. But as long as there are experienced people, there is a skill in choosing the ul electronic line.

   First: learn from peers, learn from the peers, you can first launch the product;

   Second: Constantly optimize your peers to make your choices more suitable for your product, regardless of cost, performance and environmental requirements.

   Of course, you can also make it simple, you can call us directly, I believe that our customer service will be happy to provide you with his professional advice for you to choose.

   Third, the product appearance is smooth and round, and the color is even. Wire and cable enterprises that meet the requirements of national standards, in order to improve product quality, to ensure that products meet the requirements of national standards, in the raw material purchase, production equipment, production processes and other aspects of strict control. Therefore, the appearance of the produced wire and cable products meets the standard requirements: smooth and round, and uniform in color. The appearance of counterfeit and inferior products is rough and dull. For the rubber insulated flexible cable, the appearance is required to be round, and the sheath, the insulation, and the conductor are not easily peeled off. The counterfeit and inferior products have a rough appearance, a large ovality, and a low insulation strength of the sheath, which can be torn off by hand. ,

    Fourth, the conductor is shiny, DC resistance, conductor structure size, etc. meet the requirements of national standards. Wire and cable products that meet the requirements of national standards, whether it is aluminum conductor or copper conductor, are bright and oil-free. Therefore, the DC resistance of the conductor is in full compliance with national standards, with good electrical conductivity and high safety.

   Ul electronic line installation, it is best to transport the ul electronic wire reel directly to the present, to avoid rolling ul electronic wire reel, if the ul electronic wire reel can not be directly installed on the device, ul electronic wire should be with the help of the pulley mechanism Use the rope to unfold the ul electronic wire from the ul electronic wire reel; during the unfolding of the ul electronic wire, maintain a certain pulling force to ensure that the ul electronic wire does not tilt or move on the edge with sharp sharp edges, ul electronic wire It should be removed from the top of the rotating ul electronic wire reel.

    Before the ul electronic line is installed on the equipment reel, the ul electronic line should be fully deployed. If there is no such condition, the distance between the ul electronic reel and the equipment reel should be extended as much as possible to avoid the ul electronic line being laid. The bending will be skewed; when connecting and fastening to the point of entry, the ul wire should be avoided; during the installation process, if the ul wire crosses the point of entry, a compensating pulley of equivalent diameter should be used to wind the ul Line 1-2 turns, if the point of entry is below the ground, a funnel-shaped point-in point guide is placed above the compensating pulley.

    The end of the ul electron wire is fixed by using a proportional clamp to avoid ul-electron wire extrusion. The length of the unwound ul wire before the fastening point is greater than 40*D. It is also preferable to install a compensation pulley here. When the ul wire is extended from the device roll, it remains on the device reel. The ul electron line cannot be less than 2 turns; the ul electron line has an outer diameter of less than 21.5 mm, and the inner bend diameter should be kept at 10 times the diameter of the ul electron line, and the ul electronic line has an outer diameter of 21.5 mm. It should be kept above 12.5 times ul electron wire diameter. For power applications, the outer diameter of the ul electron wire with an outer diameter of less than 21.5 mm should not be less than 5 times the diameter of the ul electron wire. For ul electrons with a diameter greater than 21.5 mm. For the line, the inner bending radius should not be less than 6.25 times the ul electron line diameter.
