Outdoor High Voltage Ceramics/Polymers Drop Out Fuse Cutout

(H)RW12-12(F)outdoor high-votage AC drop type fuse (hereinafter referred to as "fuse")is suitable for outdoor overhead distribution systems with a rated frequency of 50Hz and a rated voltage of 10kV.It serves as a protective element for circuits or electrical equipment in the event of overload or short circuit faultsin the power system.When the fuse operatesnormally,itis connected in series inthe power
ine,with the fuse in a taut state and the movable joint locked.When a fault occurs in the circuit,the fault currentcauses the fuse to melt, the movable joint to be released,and the fuse tube quicky drops,cuting off the circui and providing safety protection for the maintenance of the circuit and equipment.Loadtype fuses add elastic contacts and arc extinguishing covers on the basis of ordinary types,used for breaking and closing load currents in power systems.
The fuse complies with technical standards such as GBT 15166.3-2008"High voltage AC Fuses Part 3:Jet Fuses"and DLT 640-1997
"Technical Conditions for Ordering Outdoor AC High Voltage Drop type Fuses and Fuses".

◇ Insulators are made of high-strength ceramic or imported siicone rubber insulation materials,with a large creep distance design, strong pollution resistance and environmental adaptability,excellent insulation performance,and meeting the operational requirements in high-altitude areas;

◇ The upper contact adopts a siver to siver design,and the stainless steel spring of the contact provides high contact pressure,ensuring good conductive contact and minimal contact resistance,not exceeding 300μQ;

◇ The lower contact adopts a siver to siver design,providing a pair of current paths that are not connected to the hinge shaft optical feet;

◇ The fuse tube adopts an epoxy phenolic glass cloth tube with a fiber lining with a special UV resistant coating,which has excellent UV resistance performance;

◇ The parallel groove connector is made of cast brass material,which makes the connection very simple even if the size is not consistent due to the provision of two conduits;

◇ The ear shaftis made of high-strength cast bronze material and coated with siver on the surface,which is pressed on the surface of the hinge to ensure accurate alignment of the fuse tube during closing;

◇ The design of the baffle fully satisfies the rapid separation of the ends,the cable strands quickly pop out,and can reduce the force transmitted to the fuse chain when closed;

◇ The sleeve joint ensures reliable release after cutting;

◇ The rated current of the same family of fuse components is high,up to 200A,and the breaking capacity is strong,up to 16kA;

◇According to user requirements,additional electrical grounding fixing devices can be added to failitate users in conducting electrical grounding operations.
