Product Decription:
K Type Fuse Link Elements are used for 11-38KV drop out fuse. The Fuse Element adopts the accurately tested material, high purity silver, or silver-copper eutectic or nickle-chrome eutectic, based on different rated current. The fuse element wire is extruded by mold of high accuracy. The cross section is inspected by laser micrometer to ensure the accuracy, while careful assembly guarantees no crack, shrinkage or twist which affects the time-current accuracy.

JEC Type K, T, H fuse links are made in complete accordance with standards ANSI/NEMA.
Precision - The standard of JEC fuse links
JEC K Type Fuse Link Elements assure system protection because they are precision manufactured. The fusible materials used in JEC Fuse Links are under continual control during manufacture. Pre-tested to guarantee their electrical values, these materials are held to precise tolerances. At critical points during the manufacturing process, rigid inspections are made.
Structure of Fuse Elements:
A. Removable button head, which can be cooperated with arc shortening rod.
B. Fuse element: eutectic alloy which can be melted of low temperature to avoid the burning of arc-extinguishing tube
C. High strength strain wire, which can withstand the tensile strength from fuse cutout flipper and outside pulling strength.
D. Swaged connected end, guarantees the reliable connection of elements and are note easily damaged.
E. Swaged cable section prevents splaying of strands of cable, to ensure the cable's smooth withdrawal from tube during the melting fuse link.
F. Tinned copper stranded cable, resists corrosion, its cable diameter can resist corona.
G. Auxiliary arc-extinguishing tube, improves the capability of interrupting low fault current, and has the special ability to interrupt full range fault.
Packaging:
JEC fuse links come in protective plastic bags with perforations to facilitate quick, easy opening even when lineman's gloves are worn. Each bag remains completely sealed for all-weather protection and keeps the links protected in the line truck's bins.
Type and amperage is printed on each bag, for easy identification.
