The high voltage switchgear is a metal-clad cabinet for the listed 12kV distribution system. Its internal sections separate the busbar, switching and cable functions. A withdrawable truck provides defined operating positions for the selected circuit equipment. Breaker, metering, voltage-transformer and isolation arrangements serve different feeder roles within the range. The protective and control interfaces connect those functions to the electrical scheme. Cabinet protection levels differ between the closed enclosure and accessible internal areas. Selection therefore includes the truck function, cable arrangement and required operating interfaces, alongside the rated voltage and current of the completed cabinet.

Main Applications
• The high voltage switchgear receives power at industrial 12kV substations.
• Distribution rooms use separate breaker, metering or isolation trucks to perform different circuit duties.
• Compartmented indoor lineups suit feeder control and monitoring in plant electrical networks.
• Different truck functions let a switchboard perform more than one circuit task. A breaker feeder, metering position and isolation section can occupy separate cabinets within a coordinated indoor distribution lineup, with the selected protection scheme determining how each part is used.
Why choose us
We prepare high voltage switchgear from the approved breaker and cable arrangement. Production review covers the truck function, cabinet compartments and protective-control interfaces before assembly. Our workshop can coordinate the enclosure and installed components within one order. That makes cabinet identification and technical clarification easier when a project contains several feeder types or requires matching units for later expansion.
For an expansion order, identify the existing feeder function and cabinet interfaces so the proposed unit can be compared with the installed lineup before assembly.


FAQ
Q: Can this model operate on a 35kV supply?
A: No. KYN28A-12 is rated for a 12kV system.
Q: Are several truck functions available?
A: Yes. Breaker, voltage-transformer, metering and isolation configurations are listed for different circuit roles.
Q: Does the enclosure provide IP4X protection?
A: Yes. IP2X applies between compartments and when the breaker-room door is open.
