The Expulsion Fuse Cut out is a low cost line protection switchgear, primarily used on remote overhead electrical transmission lines. The visual display of the status of the fuse cut out (“Disconnected” or “in Operation”) helps field inspectors to locate the faulty segment of the overhead transmission line quickly and accurately. Upon clearing of the line fault and replacing the fuse link, each of the phases can then be individually switched back into operation using operating poles, which are available in desired lengths..
The latest trend in fuse cut outs is the use of silicone insulators instead of the conventional porcelain type. The HS Switchgear fzco built fuse cut out, rated up to 27 kV, uses high quality silicone insulators and has a sturdy design to withstand the harsh outdoor environment prevalent in this part of the world
Successful type tests at IPH, Germany and ASTA Certification fully establishes the reliability and efficient performance credentials of this product from HS Switchgear fzco. Customized creepage distances can be achieved on our insulator design and fuse links of desired current ratings of up to 100 A, can be easily accommodated. Please refer to the attached table of specifications for the HS Switchgear fzco fuse cut out that fully complies with IEC standards.
