The purchase of power cables is a process that needs to consider a number of factors, the following are some scientific recommendations:

1. Determine requirements: Determine the type, specifications, and length of the required power cable based on actual requirements.

2. Understand the cable performance: Different types of cables have different performance and scope of application. It is necessary to understand the conductor materials, insulation materials, temperature resistance level, current carrying capacity and other performance indicators of various cables in order to choose the right cable.

3. Focus on brand and quality: Choosing a cable manufacturer with reliable brand and quality can reduce the procurement risk and ensure the quality and performance of the cable.

4. Check appearance and label: Observe whether the appearance of the cable is smooth and round, whether the color is uniform, and whether the label is clear and accurate. At the same time, check whether the manufacturer name, product model and rated voltage on the cable surface are consistent with the information on the certificate.

5. Check the conductor: whether it is aluminum conductor or copper conductor, it should be bright and free of oil. Pay attention to whether the conductor wire diameter is consistent with the section indicated on the certificate, if the conductor section is too small, it is easy to make the wire heat and cause danger.

6. Measuring length: Length is the main intuitive way to distinguish between products that meet national standards and fake and shoddy products. When purchasing, do not covet the price is cheap, buy 90m or 80m, or even no length identification of wire and cable, the length must meet the standard requirements of 100±0.5m, that is, 100 meters as the standard, allowing an error of 0.5 meters).

7. Consider laying conditions: Different types of cables can be selected according to different laying conditions. For example, in areas with more mechanical damage factors and erosion factors, armored cables can be selected; In the case of high drop and vertical laying, plastic insulated cable can be selected; In the presence of corrosive gases or objects in the environment, you can choose anti-corrosion cables.

8. Consider safety: Cables with special safety performance such as low-smoke halogen-free cables or flame-retardant cables can be selected according to needs.

To sum up, the purchase of power cables needs to consider many aspects, including demand, performance, brand, quality, appearance, logo, conductor, length, laying conditions and safety. Only by taking these factors into account can we choose the right power cable.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
