Ring Main Unit 24kv 630A Load Breaker Switch with Fuse

Product DescriptionFLN36-12 is the main switch in the ring main unit. It complies with technical requirements of IEC 420, 694 and 129, GB3804-2004 "High-voltage Alternating-current Switches for Rated Voltage above 3.6 KV and less than 40.5 KV", GB1985-2004 "High-voltage Alternating-current Disconnectors and Earthing Switches", GB/T11022-1999 "Common Specifications for High-voltage Switchgear and Controlgear Standards".FLN36-12 is a switch with closing, opening and grounding function. 0.05 MPa SF6 gas is filled into the epoxy shell with strengthening structure to realize these three functions with the least parts, which guarantees the quality and improve the reliability. It is maintenance-free and could run for 20 years safely in the normal condition.Product Parameters  No.ItemUnitData1Rated VoltagekV12/24/362Rated FrequencyHz503Rated CurrentA6304Rated Peak Withstand CurrentkA5054s Rated Short-time Withstand CurrentkA206Rated Making CurrentkA507Rated Breaking CurrentActive Load Breaking CurrentkA630Breaking Current LoopA630Cable Charging Breaking CurrentA1081min Power Frequency Withstand Voltage (Phase to Phase, to earth, fracture)kV42/489Lightning Impulse Withstand Voltage (Phase to Phase, to earth, fracture)kV75/8510Relative Pressure of SF6 gas (20ºC GP)Mpa≤0.0411Rated Operating Voltage (electric)VAC220/DC22012Rated Voltage of Shunt ReleaseVAC220/DC22013Average Opening Speedm/s3.5±1.514Average Closing Speedm/s3.5±1.515Three-phase points, Closing Phase of the samems≤316The main Circuit ResistanceμΩ≤12017Manual Maximum TorqueN.m≤16018Phase to Phase Center Distancemm210±0.5   Related Products WarehouseProject CasesCertificationsFAQQ: Could I have prices of your products?A: Welcome.
