How to tell the mass of the electron harness

Electronic wiring harness is short for internal wiring of electrical equipment. Power-on is mainly based on weak current, which is different from the cable in the strong current field. Electronic wire is divided into three series: UL standard, 3C standard and VDE standard. AWG units are usually UL standard and cross section square units are usually 3C standard or VDE standard. Domestic electronic wire manufacturers mainly use 3C or UL as the main standards.
1. When selecting, please try to select products that meet the specifications. Electric wire and cable are listed as mandatory safety certification products in our country. All production companies must obtain CCC marks certified by our electrical product Certification Committee, and mark certificates and CCC marks on their products. Export goods must pay attention to the United States UL regulations and European Union environmental RoHS requirements.
2. In terms of features and specifications, it is not easy to choose the right wire for your requirements among the clutter, confusion and hundreds of wires. But from actual combat experience, this is not difficult. It can be divided into two steps. At the top of the list, learn from and learn from your peers. You can start the product first. Second, continue to optimize the practices of your peers to make the products you choose work better for you, regardless of cost, functionality, and environmental requirements. Of course, you can also simplify the complexity and go directly to our customer service, who will be willing to provide professional advice for you to choose from.
3. The product appearance is smooth and round, uniform color. Wire and cable companies whose products meet national requirements strictly control the procurement of raw materials, production equipment and production technology to improve product quality and ensure that products meet national requirements. Rules.
As a result, the appearance of the wires and cables produced meets the requirements of the code: lubrication, roundness and uniformity of color. The appearance of counterfeit goods is rough and dull. As for rubber insulated flexible cables, they are required to have a rounded appearance, tight sheathing, insulation and conductors that are not easy to peel off. The counterfeit goods have a rough appearance, high ellipticity and low insulation of the sheathing, which can be torn off by hand.
4. The conductor is glossy, DC resistance and conductor size meet the requirements of national regulations. In line with the requirements of national regulations of wire and cable products, whether aluminum conductor or copper conductor, are bright and not greasy. Therefore, the DC resistance of the conductor fully conforms to the national regulations and has excellent performance.
