Fiber glass fuse tube for fuse cutout:

Fiber glass fuse tube for fuse cutout:

The fuse cutout is connected with the incoming feeder of the distribution transformer or distribution line. These are mainly used to protect transformers or lines from short circuits and overloads and switching currents. The drop out fuse unit is composed of insulator supports and a fuse tube. The fuse tube we produce is composed of epoxy glass fiber pipe outside and arc-extinguishing vulcanized pipe inside.

Anwendung:

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

It is mainly used for structural parts of high-voltage electrical equipment such as lightning arresters (bushings), current limiting fuse boxes, connecting rods, grounding rods, etc., such as reactors, lightning arresters, fuses, transformers, on load tap changers, transformers, and some high-voltage electrical and gas equipment that require good insulation resistance and arc resistance. The product performance parameters meet the requirements of IEC standards, and the product is in a leading position in China.

Fiber glass fuse tube for fuse cutout Material:
