The domestic Nanjing bridge market is turbulent, with many brands, different quality, and different consumer technologies and raw materials, resulting in huge price differences. Buying bridges has become a major problem for consumers. So how to buy cheap bridges in a chaotic market? Nanjing Ruiquan Electric will show you how to choose the quality of bridges and how to accept them.
How to choose the quality of the bridge?
The first thing to understand is that the raw materials for the consumption of the bridge are mainly insulation materials, electrolytic copper, and sheath materials. The quality of the bridge is largely determined by the raw materials. When choosing the quality of the bridge, pay attention to the following points:
1.The color of the bridge
People in the industry have introduced that the reddishness of the common copper core yellow indicates that the raw material copper used is of excellent quality, and the copper core is purple black, indicating that there are more impurities and it is easy to break. If you buy an aluminum core wire, you don't need to buy the dull and dull, the good quality aluminum core is bright snow white.
2, the appearance of the bridge
Whether the appearance can have a quality system certification, whether there is a certificate of conformity, and the certificate can be forged. When you check it, you must take it seriously and check whether it is standard. Whether the basic information such as trademarks, specifications, and voltages are complete, and those with incomplete basic information must not be purchased. For the sake of insurance, unpack the outer layer and see if the bridge maintenance insulation layer can be lubricated and damaged.
3.The price of the bridge
The price is ridiculously low. At this time, you must be careful. As people are getting smarter today, many unscrupulous wrists can hardly imagine it, so many unscrupulous merchants sell cheap wires and cables under the guise of good quality and low price.
4, bridge feel
Glide quietly on the bridge with your hands, with or without scratching, how to feel soft and flexible, which demonstrates that the quality of the bridge is excellent and can be purchased.
How should the bridge be accepted?

2. It is necessary for the type, standard and quantity of the bridge to be common with the purchase order. The raw materials and thickness should meet the request.

The thickness of the connecting plate is the same as that of the bridge.
3. Assemble the on-site assembly of linear grooves, components, etc. to check whether the joints are uniform and not greater than 1mm.
