Fiberglass/vulcanized Fiber Combination Tube - Epoxy Resin Saturated | No-spark Generating, Uv Resistant, Arc-quenching Gas Features

Our provided Combination Tube is made by over wrapping vulcanized fiber tube with epoxy resin saturated fiberglass filaments. The angle of filament winding is usually set at 55A . Vulcanized fiber tube becomes an integral tube liner which provides gas-generating and arc-quenching characteristics. Epoxy resin saturated fiberglass provides strength and water resistance. The combination tube is usually coated with UV resistant paint in gray color.

Fiberglass/vulcanized fiber combination tube has the following advantages over fiberglass/polymeric synthetics combination tube: no-spark generating, char layer forming to prevent liner from excessive ablation, and the optimum amount of arc-quenching gas generating. The main application of fiberglass/vulcanized fiber combination tube is used in expulsion fuse tube cutout for interrupting high voltage AC circuits during power surge.
