Introduction to the wire production process of Guangdong Cable FactoryThe wire production process of Guangdong Cable Factory involves many links. Below I will introduce you to the general wire production process. The first is the preparation of raw materials. The main raw materials of wires include copper wire, aluminum wire, insulation materials, etc. During the production process, raw materials that meet quality standards need to be prepared according to product specifications and requirements, and necessary inspections must be conducted. Next is conductor manufacturing. In the wire production process, copper or aluminum wires first need to be made into conductors of appropriate size and diameter through processes such as drawing. This step is very important and affects the electrical conductivity and mechanical properties of the wire. Then comes the insulation treatment. After the conductor is prepared, it needs to be insulated. This step is to coat the surface of the conductor with insulating material to protect the conductor from damage from the external environment. Commonly used insulation materials include polyethylene, polyvinyl chloride, etc. Followed by the braid layer (if any). For some special types of wire, a braid may be required. The braid provides additional protection and increases the wire's abrasion resistance and tensile strength. Next is the sheath treatment. The sheathing of the wire helps protect the wire from mechanical damage and corrosion from the external environment. The sheath is usually made of polyvinyl chloride and other materials, and sheaths of different colors and materials can be selected according to needs. The last step is cutting and coiling. After processing in the previous steps, the main structure of the wire has been completed. Next, the wire is cut to the required length, coiled, and packaged. This way, the wire can be easily stored and transported. In a word, the wire production process of Guangdong Cable Factory has gone through raw material preparation, conductor manufacturing, insulation processing, braiding layer (if any), sheath processing, cutting and coiling. The operation and control of each link are crucial to ensure that the quality and performance of the wires meet product standards and meet customer needs.
Why are solar cables more expensive than regular cables? 一、Price difference between solar cables and ordinary cablesCompared to ordinary cables, solar cables have higher requirements for material and technical performance, and their prices are also relatively high. The price of single core solar cables with pure copper conductors is relatively higher than that of multi-core cables with aluminum alloy conductors. Therefore, the price of solar cables varies depending on the application scenario and material.二、Characteristics and application scenarios of different types of solar cables1. Single core solar cableThe production process requirements for single core solar cables are particularly high, and high-purity copper is required as the conductor, and high temperature and high pressure injection molding technology is used for processing. The key components of photovoltaic power stations in the market are all single core cables, and the price per unit length is also higher than ordinary cables.2. Multi core solar cablesCompared to single core solar cables, multi-core solar cables are relatively cheaper in price. The multi-core solar power supply line is PV1-F line, and TUV certification has stronger reliability because it has characteristics such as environmental protection, fire resistance, tunability, high temperature resistance, and slim shell.3. Solar cables for DC junction boxesThe solar cables used in solar DC junction boxes can be certified for packaging color, length, and standard, and can also be customized for wiring color and length. It often has multiple characteristics such as fire resistance, high temperature resistance, low smoke and halogen-free.三、How to choose the appropriate solar cableThe price of solar cables varies due to different application scenarios and materials. So, when making a purchase, it is important to consider one's own industry, technology, and scenario to determine whether it is necessary to choose high-quality products with higher prices.When choosing, the first thing to consider is the actual application scenario of the cable. If it is a key cable for solar photovoltaic power generation systems, it is necessary to consider its long-term use in outdoor environments, as well as the durability and safety of the cable. At this point, it is recommended to choose single core solar cables or TUV certified photovoltaic cables with higher prices.If it is only used for auxiliary transmission cables, ordinary solar cables can be chosen, which can meet the demand and have a relatively low price.In short, when purchasing solar cables, we need to consider the actual demand and price level comprehensively. Meanwhile, to ensure the quality of cables, it is recommended to choose products produced by reputable manufacturers.If you want to know more, please feel free to contact us >>
The usage environment of photovoltaic cablesPhotovoltaic cable is mainly used for outdoor environment work, photovoltaic cable can be used to connect the photovoltaic system equipment and the building electricity equipment, from the use of the environment on the performance requirements of the cable, photovoltaic cable needs to meet three requirements:1, flame retardant2, should have the characteristics of anti-ultraviolet aging, moisture resistance and high and low temperature resistance 3、Anti-thermal oxygen agingIn addition, it can also be added to the previous only for some special electrical equipment with cables only require oil resistance, acid and alkali resistance and ozone resistance and other aspects of performance, this complexity, is rarely encountered in the past all types of cables.The complexity of photovoltaic cables is also reflected in the following requirements: the products are used in ambient temperatures ranging from -40°C to +90°C, the conductor's long-term operating temperature is 120°C, the operating temperature does not exceed 120°C within 5 seconds of a short circuit, and the service life is not less than 25 years.
What are the structures of wires and cables composed of? The structural components of wires and cables are: insulation protection layer, shielding layer, and wire core, among which the insulation layer can ensure electrical energy output and is an indispensable part of wires and cables. So how to distinguish the quality of wires and cables? Let's explain it to you below.Method for distinguishing the quality of wires and cables:The surface shows a regular "unevenness" of the mesh inside the compression, indicating good processing technology and no relative sliding, making it a good cable. The appearance is smooth, and the "unevenness" of the pressed mesh cannot be seen. The sheath feels loose when pinched by hand, which is poor for cables;
