Fixed AC Metal-clad Ring Main Switchgear HKT1-12C

Fixed AC Metal-clad Ring Main Switchgear HKT1-12C

HKT1A-12 Combined Fixed AC Metal-clad RMU Switchgear, its switch is GT2-12/630-20 rotary and insulation disconnector and FZN17-12/T 630-20 vacuum load switch and composite electric appliances. And all the components are the most advanced products at home now. This RMU is up to IEC 298 standard [Alternative Current Metal-clad Switchgear from 1kV to 52kV, including 52kV] and GB3906 [3-35KV AC Metal-clad Switchgear] . At the same time£¬it has reliable false-protected measure requested by Two Section. The protection level of the enclosure is IP3X and of the compartment is IP2X.  It is suitable for power supply system with 10kv rated voltage and 50HZ rated frequency in places, such as industrial and mining enterprises, residential district, high rise buildings, schools, parks, etc to accept and distribute power supply. It can be applied to RM power supply and terminal power supply system.

Product feature :
      a. The designation of the product structure is initiate in China and the technology is ahead at home as well.
      b. It is featured by miniaturization, insulation, without oil and simplification.
      c. Its enclosure are zinc steel plates coated with aluminum.
      d. It is fitted in vacuum load switch on the side and composite apparatus. The designation of the load switch has been improved on the basis of FN16A and both of its parameter and technology are superior to FN16A products.
      e. It is fitted in insulation epoxy casting and rotary disconnector, of which the three-phase moving contacts are casting with principle axis. The static contact and the moving contact are on a multipoint connection. The static contact can be adjusted automatically.
      f. It is not necessary to maintain the vacuum load switch of the main switch room, it is so small that it is necessary for maintaining the operating mechanism of motor drive and manual drive.
      g. The mechanical interlock is simple and reliable that it can prevent from incorrect manipulation and can be easily operated. The disconnector and the earthing switch interconnect and their operating height is 1000mm more or less, which are suitable for human physiology characteristic.
      h. Through the view window, two isolating distances and cable terminal connections can be observed.
      i. There are multi-locks on the door. The busbar room is sealed. There are pressure release passages on the ceiling and at the back of the switchgear. The protection level is IP3X and IP2X of the compartments. The insulating plate is not used while examining and repairing.
