UPREME FUSE LINK (Expulsion Type)

Fuse cut-outs play very important role in system and equipment protection on overhead distribution systems. The key determinant of a cut-out's ability to function properly is the fuse link it uses. Failure of the fuse link to perform asplanned can result in mis-coordination with other protective devices, nuisance operations and needless outages.To a utility that's money and not just the cost of the replacement fuse link. The expense of finding and replacing fuselinks that sneak out can cost many times the up-front savings achieved through the use of less-expensive fuse links.SUPREME's Fuse Links eliminate nuisance fuse operations and, at the same time, provide reliable protection in theevent of a fault within the cut-out's zone of protection. They're manufactured in accordance with a quality systemcertified to ISO9001:2000.

Salient Features

• High Mechanical Strength. SUPREME Fuse Links have permanently accurate time-current characteristicsas per IEC-60282-2 (Tests on Heat Run & Time Current Characteristics have been successfully carried outfrom Jadavpur University, Kolkata ). They're unaffected by mechanical shock, vibration, or transient currentsurges that heat the element nearly to the severing pointeliminating sneak-outs.
• Close Melting-Current Tolerance. SUPREME Fuse Links have a melting-current tolerance permitting closer fusing for improved protection, more precise series coordination for enhanced service reliability.
• Superior Fault-Interrupting Performance. SUPREME Fuse Links provide protection against all types offaults, including low-current transformer secondary-side faults.

Constructional Features

• FUSE ELEMENTS

Elements consist of special alloy wire to protect from overheating during full load. The fuse elements are crimpedjointed by ferrule/sleeve with stranded tinned copper flexible wire rope tails made of 37 SWG wires. The overallDimensions of 11 KV D.O. fuse elements tails are shown in the drawing.

• FIBER GLASS TUBE

The central portions of the Fuse Elements are having a protecting device made of good quality FIBER GLASS TUBEwhich are manufactured from the best quality of Electrical grade insulating materials of high temperature range.

• FLEXIBLE TAIL ROPE WIRES

FLEXIBLE TAIL ROPE WIRESThe D.O. fuse elements are crimped jointed by ferrule/sleeve with two stranded tinned copper flexible wire rope tailsmade of 37 SWG. Stranded tinned copper flexible wire ropes are manufactured by our own stranding machine fromElectrical Grade 100% tinned copper wires.
