filament winding wound Insulated insulating fiber glass tube for current-limiting fuse HRC fule
filament winding wound Insulated insulating fiber glass tube for current-limiting fuse HRC fule
The insulated fiberglass tube is a filament winding process tube, The filament angle is 45~65°, It also can be adjust different angle for best performance.The insulated fiberglass tube was used for current limiting fuse/High Rupturing Capacity fuse. It also used for Development of high-voltage electrical equipment structural parts such as reactor, lightning arrester, fuse, transformer, on load tap changer, transformer, etc. The performance parameters meet the requirements of IEC standard.
