  Customized products can consult online customer service!  PRODUCT DETAILSHigh-Reliable Gas Insulated SF6 Switchgear IDescription:      RM6(XGND)-12 fully insulated fully enclosed compact switchgear, which can realize functions of control, protection, measurement, monitoring, communication, etc. is especially suitable for places with small distribution facility sites and high-reliability requirements, and places with a relatively harsh natural environment and conditions, such as underground, highland and coastal areas. It is mainly used in areas where land is tight and space is limited, high reliability is required, like industrial and mining enterprises and substations, subways, light rail railways, etc. It combines microprocessor technology, modern network communication technology and new switch manufacturing technology to effectively separate and combine load current and short circuit current.        The measurement protection control and communication functions configured inside the device can fully meet the requirements of the distribution automation system. The conductive parts of the high voltage components such as circuit breakers, three working position switches and load break switches in the main circuit are installed in a sealed cabinet-type stainless steel casing. The biggest feature is that it is not affected by the external environment, and has high reliability and can make the equipment run safely for a long time in places with poor environment; secondly, the size of the high voltage component is reduced, the device is miniaturized, and the parts inside the sealed casing are free from corrosion and rust, thereby eliminating the influence. In addition, with high voltage components with stable performance and long electrical life, maintenance-free or fewer maintenance requirements can be achievedTECHNICAL PARAMETERThe technical parameters of the form are for reference only.Customized products can consult online customer service!NO.ItemsUnitValue   Load breakswitchCombinationVacuum circuit breakerDisconnect/earth switch1Rated voltagekV122Rated frequencyHz503Power frequency withstand voltage(phase-to-phase/across open contacts)kV42/484Lightning impulse withstand voltage(phase-to-phase/across open contacts)kV75/855Rated currentA630See note 16306306Rated closed-loop breaking currentA630   7Rated cable charging breaking currentA10   8Rated short circuit making current (peak)kA508050 9Rated peak withstand currentkA50   10Rated short time withstand currentkA/4s2011Rated short circuit currentkA 31.520 12Rated transfer currentkA 1700  13Max. current of equipped fusekA 125  14Circuit resistanceμΩ≤300≤600≤300 15Mechanical lifetimes5000300050002000  CLoad switch moduleWidth=325mmDCable connection module without grounding knifeWidth=325mmFLoad switch fuse combination electrical moduleWidth=325mmVVacuum circuit breaker moduleWidth=325mmSLBusbar segmentation switch module (load switch)Width=325mmSvBrBusbar segmentation switch module (vacuum circuit breaker) SV is always with the bus lifting moduleWidth=650mmMMeter module 12kVWidth=695mmPTModuleWidth=370 or 695mmNote: A single module must add extension before it can be used.THE USE OF CONDITIONS Altitude: not more than 2000mAmbient temperature: maximum temperature +40ºC; Minimum temperature -40ºCRelative humidity: ≤95%Earthquake intensity: 9Installation place: the place where there is no water drop, fire, explosion danger, serious pollution, chemical corrosion and violent vibrationRELATED PRODUCTS COMPANY INFORMATION         Zhejiang ZheGui Electric Co., Ltd was established in 2013.
