HMF-MAK Training – Secondary (Multicore schedule Secondary Multicore cable routes secondary)

Objectives
• Understand the purpose and structure of a multicore cable schedule.
• Learn to review cable routing for segregation, sizing, and interference.
• Identify requirements for different cable types (control, power, instrumentation).

Key Topics
• Cable Schedule: Core numbering, function designations, from/to locations, cable type.
• Segregation Principles: Separation of power, control, and sensitive communication cables to minimize EMC interference.
• Routing: Panel-to-panel, panel-to-switchyard, marshalling kiosks.
• Core allocation for different signal types (analog, digital, trip, interlock).
• Thermal rating and voltage drop considerations for DC cables.

Practical Focus
• Review of a multicore schedule for a typical protection and control panel.
• Exercise: Tracing a specific signal (e.g., a trip command) from relay to breaker via the cable schedule and routing diagram.

Suggested Diagrams
• Example of a multicore cable schedule spreadsheet.
• A block diagram showing secondary cable routes from the control room to the switchyard, highlighting segregation (e.g., separate trays/trenches).

Key Takeaways
• Skill to manage and verify complex cabling databases.
• Understanding of EMC and safety principles in secondary cabling design.
