How high a temperature can high temperature resistant wire and cable withstand?

Cables are particularly diverse, there are high temperature resistant cables, fire resistant wire and cable, low temperature resistant cable line and so on these, because the role is not the same, so it is used in different fields. From the surface meaning we understand that high temperature resistance is the high temperature under the state of operation, but do you know how high the temperature is usually?

Long-term continuous working environment temperature of 125 degrees, 135 degrees, 150 degrees, 180 degrees, 200 degrees, 250 degrees and 250 degrees above is called high temperature wire and cable, the most commonly used at this stage are irradiated cross-linked polyolefin, silicone rubber, fluorine resin, polyamideimide, mica, magnesium oxide and other cables and wires. Heat-resistant cable wire and high temperature wire and cable must meet two requirements. This kind is the cable wire working environment temperature is relatively high, cable wire in the long high temperature can be normal signal transmission or electricity, the other type is the power transmission cable wire, usually to increase the interception capacity as the main purpose. Ordinary cable wire at high temperatures when prone to insulation aging and scorching conditions, the use of cable wire to lose characteristics, subject to damage and can not be used. High-temperature cable in the rated high temperature can work normally and stably, signal or power transmission characteristics have no effect, but also to ensure that the cable has a relatively long service life. This type of role cable is the most common and most high temperature cable, the use of the characteristics of the most easy to understand.
