Product Name: Outdoor Gang Isolator Switch Gw1 Model NO.: GW1-12KV /630A Brand: Sasun Certification: UL, ISO, CCC Modulation System: PFAW Energy Transmission: One-way Transmission Power Supplying System: Net Work Voltage Regulating Mode: Frequency Modulation Type Starting Mode: Separate-excited Switching Power Supply Connection Mode: Series Switching Power Supply Input Voltage: 12kv Warranty: 2 Years Output Type: Multiple Trademark: Sasun Transport Package: Wooden Cases Specification: 135 x 55 x 60 cm Origin: China HS Code: 8535100000 Product Description GW1A-12KV/24KV/33KV-4001/600A/1250AOutdoor Pole Mounted Disconnector1 ,Product overview1.1 Application GW1A type outdoor AC high voltage isolation switch is AC 50Hz/60Hz outdoor device, is used in below 33 kv the supply network, for high voltage line and under the situation with voltage, as well as on the maintenance of high voltage bus, circuit breakers and other electrical equipment with high voltage line charged electrical isolation. But also switch small capacitance current and inductive current.This product is divided into regular and anti-pollution type two kinds.CJ6 Motor or CS8-5 rainproof type manual.This product can be with Arc Extinction Horn or ChamberThis product can be with Conductor in Cable or Soft BusbarThis product cab be with Fuse or without Fuse1.2 EnvironmentalAltitude≤2000m,more higher ,should be redesigning by sea levelAmbient air temperature:-40≤T≤ +50ºC;Wind pressure ≤700Pa;Seismic intensity ≤8 degree;Radial thickness of ice≤10mm;2 ,Main technical parameters Pic 1Technical sheetItemGW2-12WGW1-24WGW1-38WUr kV102033 Volts RMS kV122438Rated insulation level1Min power frequency withstand voltage kV(RMS)to earth405070Fracture476080lightning impulse withstand voltage kV(peak value)to earth105125170Fracture120145195Rated frequency Hz50/60Rated current A200,400,630,1250The thermal stability of current 4 seconds kA(RMS)6.3,12.5,20,31.5Dynamic current kA(peak value)16,31.5,50,80operating mechanism CJ6 Motor or CS8-5 rainproof type manualWith Fuse50A,100A,200A OR NonEConductorCABLE OR SOLF BUSBAR3, Construction This disconnector(Size as shown in figure 1)is the three-phase on one chassis knife switch, or made up of three single phase.As shown, can be divided into the chassis, insulator and conductive parts, chassis by the rotor and the bending of plate and Angle steel welded frame, chassis fixed six porcelain insulator, and every two composition, mounted on the rotating shaft three-phase insulator to operate, and close movement used to operating three-phase knife, conductive part is composed of contactor, knife and contact, with the spring pressure. Break-brake in turn by the operating arm shaft rotates, operating insulator up divide the knife and contact with the knife, knife touch the revolving around, contact also in knife leads up to the gate location. Turn by the operating arm shaft rotates when closing, turns operating insulator with the knife, in and after contact to meet contact rotates, together go to closing position.
