900°F (482°C) braided fiberglass insulation for use at high temperatures
This construction is one of the earliest insulations used and is perhaps still the most widely used. It consists of the single conductors insulated with a fiberglass braid then impregnated with a special binder to improve moisture and abrasion resistance. The singles are then laid parallel and a braided jacket of the same material is applied and impregnated.
While wire gauge size, calibration and atmosphere will affect the maximum useful temperature in applications, this insulation is designed to withstand a maximum continuous use at 900°F (482°C) and a single exposure use at 1000°F (537°C). Note: impregnations retained to 400°F (204°C).
Variations of this construction including protective metal coverings for improved abrasion resistance are available upon request.
