MechStream offers this essential, free KYN28 Assembly Drawing, a definitive CAD file for electrical engineers, switchgear manufacturers, and panel builders. The KYN28 is a market-leading standard for medium-voltage (MV), metal-clad, air-insulated switchgear, prized for its reliability, safety, and draw-out circuit breaker design used in 11kV to 24kV systems.

This is not a simple layout file; it is a comprehensive desenho de montagem. This resource provides the master blueprint detailing the complete construction of the switchgear panel. It meticulously outlines the relationships between the different segregated compartments: the circuit breaker (VCB) compartment, the main busbar compartment, the cable compartment, and the low-voltage (LV) control cabinet.

This drawing is critical for manufacturing, quality control, and advanced maintenance. It illustrates how components like the busbars, instrument transformers (CTs/PTs), grounding switch, and the VCB trolley mechanism integrate. By downloading this professional CAD file, you gain access to the core structural and mechanical data needed to build, install, or maintain KYN28 switchgear accurately, saving countless hours in design and reverse-engineering.

Principais recursos:

  • Comprehensive Assembly Views: Provides detailed front, side, and cross-sectional views, showing how all sub-components fit together within the metal-clad enclosure.
  • Compartment Segregation: Clearly illustrates the (PM) metallic partitions separating the four main compartments, which is critical for safety and adherence to IEC standards.
  • Detailed Component Placement: Shows the precise location and arrangement of the vacuum circuit breaker, busbar system, current/potential transformers, and grounding switch.
  • Mechanical Interlock Data: Provides the essential visual information for understanding the complex mechanical interlocks between the circuit breaker, grounding switch, and compartment doors.
  • Manufacturing & Installation Ready: A must-have blueprint for fabricators for accurate assembly, and for installers to plan cable entry, bus duct connections, and foundation.
