Qingdao Tianxing wire and cable Xiaobian to explain to you the performance of wire and cable, how to choose high-quality wire and cable. I hope our introduction can help you.

Wire and cable products are used in different occasions, so the performance requirements are multi-faceted and very extensive. On the whole, its main performance can be summarized as follows:

1, mechanical properties: refers to tensile strength, elongation, bending, elasticity, softness, vibration resistance, wear resistance and mechanical impact resistance.

2. Corrosion resistance and weather resistance: electrochemical corrosion resistance, biological corrosion resistance, chemical corrosion resistance, salt spray resistance, light resistance, cold resistance, mildew resistance and moisture resistance.

3, aging performance: refers to the mechanical stress, electrical stress, thermal stress and other external factors under the action of wire and cable, or weather conditions, wire and cable performance requirements of what products and their constituent materials to maintain the original performance of the ability.

4, thermal performance: refers to the temperature resistance of the product, working temperature, power transmission wire and cable heating and heat dissipation characteristics, current carrying capacity, short circuit and overload capacity, thermal deformation and heat shock capacity of synthetic materials, thermal expansion of materials and dripping performance of impregnation and coating materials.



How to choose wire and cable

1, depending on the certificate. This is the basic method of discrimination. To see whether the quality system certification; Second, see whether the certificate is standardized; Three to see whether the factory name, factory address, inspection seal, production date; Four to see whether the wire is printed with trademarks, specifications, voltage and other product details. At this time, do not exist subconscious sloppiness, because a little slack, the purchased products may be hidden dangers for the future quality of life.

2. Try your hand. Again for the basic steps. It is advisable to bend a wire head repeatedly by hand, any soft feel, good fatigue strength, plastic or rubber feel elastic and no cracks on the wire insulator is excellent products, in order to avoid buying defective products, don't be afraid to delay this effort.

3. Argue appearance. How to choose high-quality wire and cable, qualified wire copper core should be purple, shiny, soft feel. The shoddy wire copper core is purplish black, yellow or white, many impurities, poor mechanical strength, poor toughness, a little force will break, even in the wire often broken phenomenon. To check, just peel one end of the wire 50px, and then use a piece of white paper on the copper core slightly rub, if there is black material on the white paper, indicating that the copper core is more impurities.

4. Weigh yourself. Good quality wires are generally within the specified weight range. Here are a few sets of data for your reference. Under normal circumstances, the commonly used plastic insulated single strand copper core wire with a cross-sectional area of 1.5mm2 has a weight of 1.8-1.9kg per 100m; The 2.5mm2 plastic insulated single strand copper core wire weighs 3-3.1kg per 100m; 4.0mm2 plastic insulated single strand copper core wire weighing 4.4-4.6kg per 100m. Therefore, the poor quality of the wire is either insufficient weight, or the length is not enough, or the wire copper core impurities are too much.

5. Compare the price. Because of the low production cost of fake and shoddy wires, businesses often sell at low prices under the guise of cheap and good quality, tempting people to be fooled. Therefore, the desire for cheap psychology, must be abandoned. Otherwise, you will regret it. To sum up, wire and cable as the main transmission channel of electricity, only under the premise of excellent quality, our life will be more safe, but also more secure.
