  1.  High-temperature insulated wire 's no one-size-fits-all product. Based on the application, various factors should go into selecting the most appropriate form of wire to get the task finished right. In this post, we'll take a closer look at what these 4 elements are and exactly how they are able to aid in selecting the best high-temperature insulated wire for your specific situation.
  2.  Factor #1: Concept of Electrical Requirements - Operating voltage, conductor temperature rating and current-carrying capacity (aka ampacity) must be met when choosing high-temperature insulated wire. Such wiring is labeled which has a temperature rating, which can be determined by a variety of ambient heat and current-generated heat. Ambient heat is a result of the approval being performed whereas current-generated heat is calculated by matching conductor material and diameter to service amperage. It is important to 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.

  5.  Factor #2: Environmental Conditions - What's happening inside wire is not the only consideration with regards to selecting the right high-temperature insulated wire. External environmental factors can also be important. That's because they can use a damaging influence on both the wire's insulation as well as its interior circuitry. Ambient heat, moisture, abrasion, thermal stability, chemical attach, mechanical abuse, cold, flame resistance, simplicity of stripping terminating and routing are common environmental conditions has to be compensated for when selecting high-temperature insulated wire. Some of these factors are discussed in depth further on in this post.
  6.  Factor #3: Conductor Material Type - The wire's conductor material determine the absolute maximum temperature it may withstand. Situations that require the wire to endure the best of temperatures, like high-rise alarms in the case of a fire, could be more reliably served with nickel-coated copper and nickel conductors, both of which can endure temperatures up to 550 degrees Celsius. Copper, nickel-plated and iron conductors alternatively holds up under only a maximum array of 200 to 250 degrees Celsius.
  7.  Factor #4: Current-Carrying Capacity or Ampacity - Several of the environmental conditions stated above have an effect on high-temperature insulated wire's power to carry current. Because of this, they have to be weighed into the equation. Ampacity is measured because the current a conductor can conduct ahead of the combined temperature of both conductor and insulation rises over a permitted limit.
  8.  Conductor size and material, amperage, ambient temperature and insulation type will all may play a role may be the wire's ampacity. The conductor's diameter and mass include the most influential size considerations. The lesser these are, the bottom the high-temperature insulated wire's ampacity. As previously talked about from the Factor #3 section, a conductor's material carries a strong bearing on just how much temperature the wire can withstand which temperature range varies widely. Likewise, various materials produce wide fluctuations inside the current-carrying capacity with the wire at the same time.
  9.  Finally, the sort of insulation used in the wire determines how much heat it dissipates and, subsequently, the ampacity. The dissipation problem becomes difficult when wire is enclosed within a tightly confined space, so fire alarms in high-rise ductwork, as an example, pose additional challenges when looking for high-temperature insulated wire options.
