(H) RW11-12 (F) Series Current Limiting Porcelain High Voltage Speed Fuses Drop out Ceramic Fuse Cutout with Holder

Photos of ProductGeneral(H) RW11-12 (F) outdoor high voltage AC drop fuse (hereinafter referred to as "fuse") is applicable to the outdoor overhead distribution systems with a rated frequency of 50Hz and rated voltage of 10kV. It is used as a protective element of circuit or electrical equipment in case of overload or short circuit fault of a power system. When traveling normally, the fuse is connected in series in the power line, the fuse is in a tensioned state, and the movable joint is locked. When the line fails, the fault current causes the fuse to blow, the movable joint is released, the fuse tube is quickly dropped, and the circuit is cut off, which plays a role in safety protection for the maintenance of the line and equipment. The load type fuse is added with elastic contact and arc extinguishing cover on the basis of the ordinary type, which is used to open and close the load current in the power system.The fuse shall comply with technical standards such as GB / T 15166.3 - 2008 high voltage AC fuses - Part 3: injection fuses, DL / T 640 - 1997 outdoor AC high voltage drop tested fuses and fuse links ordering technical conditions.Model And  MeaningsTechnical Parameters  No.ItemUnitParameters1Rated FrequencyHz502Rated VoltagekV123Rated Current for Fuse of the same familyA≤100≤2004Rated Breaking CurrentkA12.5165Rated Short-Time Power Frequency Withstand VoltageTo Earth (Dry)kV/min42/1Fracture (Dry)49/1To Earth (Wet)30/1Fracture (Wet)36/16Lightning Impulse Withstand VoltageTo EarthkV75Fracture857Creepage DistancemmNot less than 300 (d-level)8Mechanical LifeTimes500Note: If the altitude is over 1000m, the rated insulation level should be modified as appropriate.Main  AdvantagesThe insulator adopts high-strength porcelain or imported silicone rubber insulation material with excellent insulation performance;The fuse tube is made of epoxy phenolic glass cloth tube with fiber lining with anti-ultraviolet special coating, which has excellent anti-ultraviolet performanceThe rated current of the same family of fuses is large, up to 200A, and the breaking capacity is strong, up to 16kA.Outline And Installation Dimension  /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
