Product Name: 12kv/24kv, 630A/ 1250A Medium Voltage Electrical Switchgear Model NO.: SM66 Current: AC Structure: Floorstanding Installation: Fixed Voltage Level: Medium Voltage Shell Material: Aluminum Alloy Certification: ISO9001 Trademark: powertech Transport Package: Wooden Packing Specification: IEC, GB Origin: Zhejiang, China HS Code: 8537109090 Product Description ++++GeneralSM66-40.5 unit type SF6 RMU with SF6 load switch as main switch, for whole cabinet is suitable for electric distribution automation and compact also expandable metal close switchgear. It characters in its simple structure, flexible operation, reliable interlocking and convenient installation etc., which can provide the satisfactory technical projects both for different application occasions and users. With the adoption of sensor technology and the protection relay up to date, plus the advanced technology and flexible assembly project, SM66-40.5 unit type SF6 RMU can completely meet the requirement of continuously variable market. It can take self-produced RLS-40.5 load break switch; also according to the demand of users can be assembled with the internationally top-ranking RCB series vacuum circuit breaker with permanent magnetic mechanism made by AREVA or HD4 type SF6 circuit breaker made by AREVA or HD4 type SF6 circuit breaker made by ABB or with our VSC-40.5 type vacuum circuit breaker with permanent magnetic mechanism. Operational methods for the main switch inside ring main unit can be either manual or electric power driven. And It can meet the requirement of "Four Controls" when matched with FTU and RTU.++++Service enviromenet:a) Air temperature: Maximum temperature: +40ºC; Minimum temperature:-25ºCb) Humidity: Monthly average humidity 95%; Daily average humidity 90% .c) Altitude above sea level: Maximum installation altitude: 2000md) Ambient air not apparently polluted by corrosive and flammable gas, vapor etc.e) No frequent violent shake++++Units for all functions:1.
