Small wires for home improvement and household use are often seen in life, but high-temperature cables are rarely seen. What is a high-temperature cable? Explain to everyone that high-temperature cables have long-term continuous working temperatures of 125 degrees, 135 degrees, 150 degrees, and 180 degrees. 200 degrees, 250 degrees and above 250 degrees are called high-temperature resistant wires and cables. There are several types of high-temperature cables. At present, radiation cross-linked polyolefin, silicone rubber, fluororesin, polyimide, mica, magnesium oxide, etc. are commonly used. Wire and Cable
At present, many domestic high-temperature wire and cable companies have entered foreign markets. However, compared with foreign local products, the competitiveness of my country's high-temperature wire and cable products needs to be improved. Here are some aspects that need to be paid attention to.
1. High-temperature wire and cable structure: Due to the high-temperature wire and cable laying environment, in addition to meeting the standard requirements, the high-temperature wire structure often has some additional requirements. For this reason, enterprises should pay attention to the design and manufacturing process of the high-temperature wire.
2. Laying conditions: The environmental conditions in West Asia, Southeast Asia and other regions are quite special. For example, in some areas, the extreme maximum temperature is 50℃, and the maximum daily average temperature is 40℃. Therefore, the technical data should pay attention to the description of the technical parameters related to the environment (such as Correction factor for flow rate).
3. Packaging of high-temperature wires and cables: For export of high-temperature wires and cables, the delivery reel generally adopts a large reel or steel reel structure, and is fully enclosed in iron sheet or wooden strips. In addition to considering the length of the high-temperature wire and the minimum allowable bending radius, the size of the container must also be considered. Strictly follow the order requirements. Since the packaging of high-temperature wires for export is more complicated than that of domestic ones, it will affect the cost and delivery time of high-temperature wires. For this reason, pay attention to the contract.
4. Other precautions: Before delivery, users should be provided with the main technical parameters, cross-section diagrams, laying instructions and other information of high-temperature wires and cables, and test reports should also be shipped with the goods. Manufacturing must strictly control the manufacturing length of high-temperature wires and cables, and the delivery length error must be minimized. All export products must pass the inspection of the State Commodity Inspection Department and issue a commodity inspection certificate.
