++++ Field for application
The FM6 is made up of modular units containing fixed or withdrawable metal-enclosed SF6 switchgear, using sulphur hexafluoride (SF6) or vacuum:
1.switch-disconnector;
2.VB4 vacuum circuit breaker;
3.JZ-10, or Rollarc 400 or 400 D contactor;
4.disconnector.
FM6 units are used for the MV section in MV/LV transformer substations in public distribution systems and MV consumer or distribution substations up to 36kV.
++++ Operating conditions
FM6 series units are designed for indoor installations (IP2XC). Their compact dimensions are:
1. 375 mm to 750 mm wide;
2.1600(1450, 1850) mm high;
3.840(1200) mm deep…
this makes for easy installation in small rooms or prefabricated substations. Cables are connected via the front.
All control functions are centralized on a front plate, thus simplifying operation. The units may be equipped with a number of accessories (relays, toroids, instrument transformers, surge arrestor, telecontrol, etc.).
++++Description
The complete unit includes the upper unit & the lower unit, the upper unit by bus-bar cubicle, load switch, operating mechanism cubicle and low-pressure cubicle, which can be assembled to be a complete cabinet with the cable cubicle of lower unit, also
separated from the lower unit (see the picture). It is safe and (Operation& LV cubicle) convenient to check & repair and reconstruct the equipment inside the upper unit and can be realized to replace the entire upper unit if necessary.
