Construction
The basic structure of the switchgear panel is comprised with the panle itself and drawable part.
The panel is assembled by bolts,the anti-corrosion steel plate is used for the shell and internal partitions.And the panel is consisted by four separated compartments,which is truck compartment,busbar compartment,cable compartment,low-voltage compartment.
There are two kinds of maintenances for this kind of switchgears,one is called front maintenance type,the other is called double-face maintenance type.And the drawable units can be divided into the following units according to its own functions.
- VCB truck
- PT truck
- Disconnect truck
- Metering truck
- HV fuse truck
- Lightning arrester truck etc.
