How to choose cold storage cable

In the process of cold storage installation, cables are an indispensable material. Although we can see a lot in the market, these cables and wires are also classified in different ways, and the power they can support is also different. The choice of what kind of wire is used in the cold storage device has a very serious significance on whether the cold storage can stop normal operation.

When choosing the wires and cables required by the cold storage device, not only need to understand how much cable I need to ensure its normal application, but also need to know how to distinguish the advantages and disadvantages of the wires, which will also affect the operation of the entire cold storage system. .

The maximum distance of the identification is below 50 cm, and it is very average. Every word is Very clear, the use of such wires can ensure that the cold storage device can operate normally;

3. Stop the identification through the core: if one of the wires of different brands under the same specification is very thick and easily torn, this means that it is a non-national standard product. If the cable is thinner, and Very strong, it is stated that it is a national standard product.

　　4. Check the inner core to identify: The inner core of the wire used to stop the cold storage device is all copper. When we look at the inner core copper when we remove the outer sheath, the brighter the copper, the better the copper;

　　5. Stop quality identification after packaging: ordinary products with higher quality can be seen at the first glance. The packaging will be very good and the disk shape is also very uniform, and the various items on the certificate are very clearly marked, there is no ambiguity in the handwriting, and the opposite is an unreliable product.

　　 Regarding the selection of the cable for the installation of the warehouse, there are mainly the above-mentioned distinguishing methods. Before choosing, you must first think about how much wire you need to meet the power supply of the cold storage, and choose the best
