Which columns should the schedule contain?
Use the project cable register or drawing list as the starting point, then cross-check the SLD, arrangements, schematics and terminal plans.
| Field | Purpose | Source |
|---|---|---|
| Cable ID | Stable identity | Cable register |
| From and to | Connection boundary | SLD or schematic |
| Type and size | Supplied cable data | Approved schedule |
| Route | Physical path | Layout or tray plan |
| Status | Review and issue | Document register |
How should a missing cable reference be handled?
Mark the row open, cite the affected source and route the question to the responsible engineer. A schedule should not create an unapproved connection.
- Cross-check both ends
- Align equipment tags
- Record source revision
- Show unknown route
- Route design questions
What should the final schedule review check?
Check that the cable schedule agrees with the SLD, protection schematics, arrangements and terminal information. Keep the native file and issued PDF aligned.
Common questions
What else should the bid team know?
What should a substation cable schedule include?
It should contain cable ID, from and to, type, size, route, termination, source and status.
Who reviews a substation cable schedule?
The drafter prepares it, while the engineer or project team confirms cable design and interfaces.
Does drafting approve the engineering design?
No. The responsible registered engineer makes design decisions and performs engineering sign-off.
