Outdoor AC HV Fuse Cutouts

Products Summarization: MCS series of outdoor cutouts include moden workmanship、with reasonable structure 、fine characteristic .The products are applied safely to protect overload current.The products are applied mainly as protective equipment in 12kV-36kV AC power system i.e. Overload and short fault protection of transformers in power supply lines and, in addition, function as capacitor aggregate and outdoor switch and can switch on/off the rated current. Standard: IEC 787 ANSI C37. 42 - 94 GB 311. 1-97 DL / 593 - 96 Characteristics: Superior performance:Combines fuse links and provides transformers, capacitors andcables used in overhead line with complete fault protection. Cuts off promptly the small or large currents fault and is capable ofinterrupting 6.3kA and 12.5kA short fault current. Maintenance free:Uses the cast cupper material to ensure the reliability of switching on/off, new materials for fuse tube and inorganic arcing materials sprayed on the tube wall. Solidity:Very strong mechanism construction. Uses the inorganic bond to conglutinates the inserting parts of assemble mechanism with inside of the insulator which can ensure operating of severaldecade without swelling of insulator. Guarantees to endure the strong dynamic and wallop caused by fault current or at time when closing. UV - resistance:smears special UV - resistant layer on the surface of fuse to prevent UV influence on the aging. Fuse:Special alloy with lower melting point, can both stabilize the time-current characteristic for the fuse and maintain the operation for long term and, in addition, the fuse arcing material is not easily aged because of slow temperature-raising. Superior mechanism performance:Inserting/disassembling simply the fuse without any precise orientating and adjusting. absorbing the dynamic with backup plate n when closing and reliable unbuckling independent upon the fault current. Design principle of button and top contacts:The stainless steel backup plate which maintainsconstant contact tension and complements the force for fuse. This plate can ensure drawing fuse prompt out of arcing tube.
