Nextel insulation a high temperature ceramic is offered with in three types of overbraiding. XC is the standard braid, XT is a tight braid and XL is a loose braid. The three braids affect only the amount of Nextel used, not the overall temperature rating. Insulation is braided over each wire or leg then a final jacket of the same insulation is braided over the pair of wires.
XC4: Nextel 440 insulation has the highest temperature rating to 1375C (2500F)

Silica insulation is a high purity (SiO2 > 99%) ceramic yarn, that offers high temperature protection up to 2000°F at an economical price. Refrasil insulation is a vitreous silica fiber.
