C(L) KSG filter reactor is suitable for reactive power compensation and harmonic control system. The filter reactor is connected with capacitor and generates the minimum impedance or maximum impedance by using the physical characteristics of LC resonance. It can absorb or block the harmonic voltage and current of the corresponding frequency in the power grid, so as to achieve the purpose of harmonic filtering, maintain the optimal value of system power factor, and make the power quality of power grid It is obviously and effectively improved. 1. The reactor has three-phase and single phase type, all of iron core dry type. 2.The iron core made of high quality low loss cold rolled oriented silicone steel sheet,core column consists of multiple gas gap,divided evenly into many small sections,gap isolated by use of epoxy resin layer pressed glass cloth,this can ensure the gap have no change during in service. 3.Coil made of H class or C class enamelled copper flat wire,laid closely and evenly,where it has perfect heat radiating performance, 4.After the core and coil are integrated together,then pre-dry,immerse into painting in vacuum chamber heat dry for solidification,H class paint used for immersion,this can solidly condense the coil and iron coil,which will reduce the noise level in service and has high heatproof class. 5.The fixing parts of core column adopted non-magnetic material, to ensure its high quality and low temperature rise. 6.Exposed surface treat for corrosion resistant, output sides utilize tinned copper pipe terminals Environmental conditions: 1. Altitude for installing place should not exceed 1000m. 2. Ambient temperature -25ºC~+45ºC, Relative humidity is not exceed 90%. 3. Environment exists without harmful gas, steam, chemical deposition. 4. The surrounding environment should be good ventilation conditions, such as in the cabinet, should be equipped with ventilation equipment.
