Wire and cable manufacturers for electrical equipment: selection of wires and cables
Electrical equipment wire and cable manufacturers: how to choose the right wire and cable, wire and cable is the product we are familiar with, in our lives in almost many places are also used, so that we can buy good quality products, the following is how to choose wire and cable, to tell you about its method.
Wire and cable are very demanding when they are used, so the quality must not be sloppy. The first thing you need to know here is that you can look at its packaging, because the national standard wires are often well-made, neat, and have a feeling of holding the quality. Then you need to open the package and look at the wires inside. Generally speaking, as long as it is a national standard wire and cable, its 1.5-6 square meters of wires require a skin thickness of 0.7mm, so you should also master these points. What's more, if it is too thick, it will not be standardized. Correspondingly, its core is definitely not enough. Therefore, the requirements in this respect should still be met. You can also choose line skin. You can pull hard. It is generally the national standard that is not easy to tear. When buying wires and cables, you can also choose to burn with fire, and those who go out within 5 seconds after leaving have a certain flame retardant function. This product will not have any problems with it.
The following are some methods and techniques for buying wire and cable. In addition, as a consumer, when buying wire and cable, you should also look at its inner core, because this speed is also very important. Generally speaking, as long as the material brightness of the inner core (copper) is higher, copper is better and the brightness is more uniform. If you find that there is no gloss when you buy it, then don't choose shiny and layering, the national standard requires that the inner core must be made of oxygen-free copper. If the target is not black rod copper, there may be potential accidents. There will be many users who do not understand these knowledge points. If you say it here, you will understand. In addition, when buying wires and cables, you should also know that the state stipulates that there must be a certain mark on the wires, and the next same mark will be marked if it does not exceed 500mm, generally, there are product trademarks, manufacturer names, implementation standards, etc. Only by mastering these can you choose the wire and cable that suits you.
What are the main points of purchasing wires and cables? Let's take a look. As the main carrier of power transmission, wire and cable are widely used in electrical equipment, lighting circuits, household appliances, etc. Its quality directly affects the quality of the project and the safety of consumers' lives and property. There are many wire varieties on the market, and appropriate wires should be used according to their own power load.
What are the precautions for wires and cables? Let's take a look. Common cable faults: wire surface markings-according to national standards, the wire surface should have continuous markings of the manufacturer's name, product model and rated voltage. This helps to find the manufacturing plant in time when there is a problem during the use of the wire, and consumers should pay attention to this when buying the wire.
There are many kinds of wire and cable products for electrical equipment on the market, which are difficult for ordinary consumers to distinguish. So what are the main categories of wire and cable products? What are the product naming principles of wire and cable? The editor brings you a brief understanding of relevant content knowledge.
The wires and cables for electrical equipment are mainly used for internal or external connection of electrical equipment, low-voltage transmission lines and various electrical signal transmission lines. Generally speaking, except for power cables, communication cables and magnet wires, most insulated wires and cables are classified as wires and cables for electrical equipment.
Electrical equipment with wire and cable is a large class of wire and cable products, a wide range of applications, many varieties, many series, large output, process type complex. The rated voltage of wires and cables for electrical equipment is low, and the working voltage is 450/750v and below, which is not more than 0.6/1kv. The working voltage of signal and instrument cables is usually 300/500v and below. The ampacity of the cable is determined according to the requirements of the cable.
Low voltage power cable winter pay attention to matters? As the weather gets colder and colder, manufacturers of low-voltage power cables usually become more difficult, which brings inconvenience to construction. Here are some precautions for winter construction. Let us take a brief look.
