Precautions when selecting cables
Cable model specifications generally refer to copper VV, YJV and other cable models and specifications. The size and current carrying capacity of the corresponding cable model specifications are very important reference basis for cable model selection.
The field of wires and cables, as the main foundational industry of the social economy, is closely related to the legitimate rights and interests of people's livelihood projects and economic and social development. Cable manufacturers teach everyone to pay attention to misconceptions in the application of wires and cables when selecting cables:
1. The low price is also a common misconception among a considerable number of customers and even some companies in the application of wires and cables. Some customers, in order to save time and neglect safety, choose these cheap, unprotected quality, and higher safety hazards of fake and inferior wires and cables. We all know that due to the safety of wires and cables and other factors, the price of wires and cables cannot meet some customer regulations. However, some individual and private companies are unable to produce wires and cables that meet national industry standards in terms of material selection, production process, testing methods, and other aspects. Its safety cannot be guaranteed, and in addition, efforts are being made to reduce the cost of short feet and meters. Due to its low price overflowing the sales market, it has complied with some customers. Therefore, please kindly ask the customer not to only purchase low-priced wires and cables.
2. The design of the design is unreasonable, and some customers have insufficient understanding of their own household appliance application regulations and natural conditions. They also have insufficient understanding of the applicable scope, regulations, and characteristics of wire and cable models, often making mistakes in model specifications. Some key units, multi-story buildings, data centers, chemical factories, public leisure and entertainment clubs, and places with centralized personnel all require the use of flame retardant or fire-resistant cables with fire safety functions; The Ministry of Coal requires that cables commonly used in deep water wells in the coal mining industry must have a flame retardant rating; There are also unique technical features such as elevator car cables, DC welding machine cables, and motor wiring.
Tips for purchasing wires and cables
If you are confused about how to choose good wires and cables, then you need to have a good understanding of your own processed products. The cable manufacturer teaches you how to purchase wires and cables.
1. From the perspective of plug-in raw materials: for wires and cables, copper core cables are naturally the raw materials. Currently, aluminum and copper wires are commonly used. As we all know, copper conductivity is much higher than aluminum, and copper mining is difficult. The mining cost of aluminum profiles is lower, which leads to two different prices for wires and cables. Naturally, aluminum wire and cable materials are lighter, and in some places, aluminum copper core cables are more suitable for selection.
2. From the perspective of insulation plastic: The appearance of plastic insulation skin is a key factor in product quality. If cable manufacturers use plastic recycling as insulation skin, their color tone is usually dim, and their thickness may become thicker, but their flexibility is very poor. The elasticity of the plastic skin is also low, and it will shatter with a little force.
If a better plastic skin is used, the color of the product will be bright and there will be no residue on the skin, so its elasticity is very good, even if stretched, it will not break easily.
