Descriptionrnrn rnrnSSOC(NCF) outdoor AC high voltage falling fuse series are the devices for overcurrent protection.The fuse installed on the distribution transformer or pole of power line serves as device for overload protection and switch on/off the load current.The fuse is composed of a main insulating and conducting structure and an arcing tube.The stationary contacts are fixed at both ends of the fuse tube composed of an arcing tube inside and an phenolic paper tube or epoxy glass tube outside.Equipped with a arcing chamber and elastic auxiliary contacts to interrupt load current and cappacitor current the SSOC(NCF)3 fuse is able to switch on/off the load current.rnrn rnrn rnrnTechnical Parameter rnMax. operation voltage 12KV/24(27)KV rnRated continuous operation current 100A/200A rnRated frequency 50HZ rnFuse base rated current 100A/200A rnRate short-circuit breaking current 12.5KA/100A 16KA/100A(1time) rn12.5KA/200A 16KA/200A(1time) rnAC voltage withstand(wet) 50KV rnAC voltage withstand(dry) 60KV rnRated lightning inpulse voltage withstand 125KV/150KV rnCreepage-distance 32.3mm/KV rnMechanical life 500times of continuous switch-off and switch-on rnElevation 2000m rnAmbient temperature -40u00b0C+70u00b0C rn
Advantage:rnrn rnrn1.Made of high conductive copper material and silver-plated on the surface for preventing from oxidation the surface the structure presents reasonable arrangement,large conductive contact area,low resistance.Discharge current capacity more than 1000A.rnrn rnrn2.Applying the superior insulating material of electrical porcelain,large creepage-distance and suitable for different environments,the design of structure is optimized for preventing efficiently the insulator from touching of bird.With tower-shaped structure,the fitting is poured and casted by USA white concrete without any swelling can withstand electrodynamic force produced by strong fault current and the impact produced by switching on.rnrn rnrn3.With thin sheet copper silver-plated structure,the cap ends of fuse tube will be penetration when heated by arc gives off the gas,presenting the effect of exhausting gradually gas of two-end.rnrn rnrn4.Composed of stainless spring,the open-close contact providing high contact pressure. rnrn rnrn5.Package:with the packing foem inside,carton outside,the suface will be prevented from oxidation for ensuring a long time maintain.rnrn rnrn6.arcing chamber for loadbreak which restricts the electrical arc and provides de-dissociation functionrnrn
