Because the specifications of each network cables are different, there is generally remark in the package of the network wire "insulation" grade, and then according to the insulation grade to check the network wire temperature.
Usually the normal temperature of the cable is in commonly 75 degrees, common in the local area network (LAN) cables are mainly three kinds of twisted pair, coaxial cable, optical cable, the cable is mostly internal copper core, external insulation materials, if the temperature is too high, external rubber to soften and internal copper coil overheating, affect the network transmission, high temperature encountered bad cable even lead to combustion.
What are the advantages of high temperature cable?
1, flame retardant: the material used to make a special high temperature cable, so its flame retardant performance is particularly good. When a short circuit or ignition temperature occurs it will not affect the series of other circuits that suddenly increase the risk, but the flame will be effective and more secure.
2, ageing-resistant performance: unlike ordinary cable, high temperature resistant, high temperature cable its insulation performance is strong, such basic requirements in some higher plant or laboratory management, etc., high temperature cables can avoid the problems that affect the short circuit or circuit, the use of students in order to achieve better teaching effect.
3. Different materials: As the name implies, other main materials are also high-temperature materials, so they can be used in high-temperature environment without affecting their main effects.High temperature cables are generally divided into fluoroplastic insulated high temperature cables, silicone rubber insulated high temperature cables, silicone rubber insulated braided cables, multi-core high temperature cables. Common cables can be made of aluminum wire or copper wire and other common materials
The use range of high temperature
Network Cable?
Suitable for network video signal transmission connection line under high temperature conditions, such as steel mill boiler, glass factory, aerospace, national defense technology, gold chemical industry, power refining, ship parking road and other high temperature fields and vehicle manufacturing, food machinery, lighting equipment, baking house flood channel, etc
Therefore, the cable is best used in the normal temperature range, if the need to operate in high temperature, it is recommended to purchase special cable and use environment.
