Product features
●Increase the heat capacity of the adapter, and significantly reduce additional temperature rise of connector, spacer plates due to the temperature rise in adapters.
●Clear and reliable division between functional units and compartments.
●Flat-mounted arrangement of bus bar permits good driving and thermal stability.
●The connecting with external cables is completed within the cable compartment, and the cable can be pulled in and out. The zero sequence current transformers are set in the cable compartment, easy for installation and maintenance.
●By the reduced current limiting reactors' matched short-circuit current, the bus bar's voltage could be stabilized at a certain value, the parts'short-circuit components strength requirement could also be reduced.
●The drawer unit has sufficient number of secondary plug-in components to meet the requirement for the numbers of connection points for computer interface and automatic control circuits.
