Product Description
Description
The Unisun enjoy more than 16 year experience manufacture SF6 Ring main Unit in china, we import first APG line from Germany to localized air pressure guage production craft, our APG manufacturing including SF6 switch disconnector, embedded pole and etc epoxy resin insulation parts. SM66 units are used for the MV section in MV/LV transformer substations in public distribution systems and MV consumer or distribution substations up to 24 kV.
Feature
The SM66 range is made up of modular units containing metal-enclosed SF6 switchgear, using Sulphur hexafluoride (SF6) or vacuum:switch-disconnector;VD4S vacuum circuit breaker;Vacuum contactor;disconnector.
Unit definitions
Below is the list of SM66 range units used in MV/LV transformer substations and industrial distribution substations:IM, IMC, IMB switch;PM fused switch;QM, QMC, QMB fuse-switch combination;CRM contactor and contactor with fuses;DM1-A, DM1-D, DM1-S single-isolationSF6 type circuit breaker;DMV-A, DMV-D, DMV-S single-isolation vacuum type circuit breaker;DM1-W, DM1-Z withdraw able single-isolationSF6 type circuit breaker;DM2 double-isolation SF6 type circuit breaker;CM, CM2 voltage transformers;GBC-A, GBC-B current and/or voltage measurements;
Standards
iSM6 units meet all the following recommendations, standards and specifications:IEC:60694:IEC62271-200IEC60265IEC60420IEC60255IEC62271-100IEC62271-102
Designation
iSM6 units are identified by a code including:an indication of the function, i.e. the electrical diagram code: IM, QM, DM1, CM, DM2, etc.the rated current: 400 - 630 - 1250 A;the rated voltage: 7.2 - 12 - 17.5 - 24 kV;the maximum short-time withstand current values: 12.5 - 16 - 20 - 25 kA.1 s;the color is of RAL 9002 type (frosted satin white).Example for a unit designated: IM 400 - 24 - 12.5IM indicates an "incoming" or "outgoing" unit;400 indicates the rated current is 400 A;24 indicates the rated voltage is 24 kV;12.5 indicates the short-time withstand current is 12.5 kA.1 s.
The hereunder values are for working temperatures from -5°C up to +40°C and for a setting up at an altitude below 1000 m.
Internal arc withstand:standard:12.5 kA. 0.7 s;
enhanced:16 kA. 1 s.
Protection index:units: IP2XC (IP3X consult us);
between compartments: IP2x.
Electro-magnetic compatibility:relays: 4 kV withstand capacity, as per recommendation IEC 60801.4;
compartments:electrical field:Temperatures:
The cubicles must be stored in a dry area freefrom dust and with limited temperature variations.for stocking: from -40°C to +70°C,for working: from -5°C to +40°C,other temperatures, consult us.
