Fuse tube for high voltage drop out fuse cutout

The tube is normally for Drop-out fuse cutout, and other places.

1.Material: 

Inner: vulcanized fiber tubes

Outer:fiberglass reinforced epoxy resin winding tube                                                                              

Surface: UV resistant insulation Painting

2.Size:

   100A:   25.4×19×13(mm)    25.4×19.05×d12.7(mm)

   200A:   36 ×26×16(mm)     31.8 ×24×16(mm)

3.Length: Max 1270mm

4.Process: Vulcanized fiber tube was wrapped by fiber glass impregnate epoxy resin ,The angle of wind is optimized to provide a finished tube with good tensile and anti explosion strength.Vulcanized fiber tube becomes an integral tube liner which have the property of gas-generating and arc-quenching characteristics. Epoxy resin fiberglass tube property of strength and water resistance.  The fiberglass tube is usually coated with UV resistant paint in gray color. 

5.Advantage: no-spark generating, char layer forming to prevent liner from excessive ablation, and the optimum amount of arc-quenching gas generating. 

6.Application :The main application of fiberglass tube is used in expulsion fuse tube cutout for interrupting high voltage AC circuits during power surge.
