High-temperature  insulated wire isn't a one-size-fits-all product. With respect to the  application, different facets goes into choosing the right kind of wire to  obtain the done right. In the following paragraphs, we'll take particular notice  at what these factors are and just how they're able to aid in selecting the best  high-temperature insulated wire to your specific situation.
Factor #1:  Definition of Electrical Requirements – Operating voltage, conductor temperature  rating and current-carrying capacity (aka ampacity) must be met when selecting  high-temperature insulated wire. Such wiring is labeled which has a temperature  rating, which can be determined by a mix of ambient heat and current-generated  heat. Ambient heat stems from the applying being performed whereas  current-generated heat is calculated by matching conductor material and diameter  to service amperage. You should note that as a result of difficulty in pinning  down exact current-carrying capacity, product designers often specify higher  capacity conductors than theoretical calculations would indicate.
Factor #2:  Environmental Conditions – What's going on inside the wire isn't only  consideration with regards to selecting the right high-temperature insulated  wire. External environmental factors will also be important. Like they're able  to possess a damaging influence on both wire's insulation along with its  interior circuitry. Ambient heat, moisture, abrasion, thermal stability,  chemical attach, mechanical abuse, low temperature, flame resistance, simple  stripping terminating and routing are all environmental conditions that must be  compensated for when choosing high-temperature insulated wire. Some factors are  discussed in greater detail further on in the following paragraphs.

Factor #3: Conductor Material Type – The wire's conductor  material determines the most temperature it could withstand. Situations that  want the wire to disclose the greatest of temperatures, like high-rise alarms in  the event of a fireplace, will be more reliably served with nickel-coated copper  and nickel conductors, because both versions can endure temperatures around 550  degrees Celsius. Copper, nickel-plated and iron conductors conversely holds up  under only a maximum variety of 200 to 250 degrees Celsius.Factor #4:  Current-Carrying Capacity or Ampacity – A portion of the environmental  conditions described above likewise have a direct impact on high-temperature  insulated wire's capacity to carry current. As a result, they have to be weighed  in to the equation. Ampacity is measured because the current a conductor can  transport before the combined temperature of both conductor and insulation rises  above a permitted limit.
Conductor size and material, amperage, ambient  temperature and insulation type will all play a role could be the wire's  ampacity. The conductor's diameter and mass are the most influential size  considerations. Smaller these are, the reduced the high-temperature insulated  wire's ampacity. As previously stated from the Factor #3 section, a conductor's  material carries a strong touching on just how much temperature the wire can  withstand knowning that temperature range varies widely. Likewise, different  materials produce wide fluctuations within the current-carrying capacity from  the wire as well.
Finally, the sort of insulation utilized in the wire  determine the amount heat it dissipates and, subsequently, the ampacity. The  dissipation problem becomes even more complicated when wire is enclosed in the  tightly confined space, so fire alarms in high-rise ductwork, for instance, pose  additional challenges when looking for high-temperature insulated wire options.
