Understand the interface decision

A conductor can have sufficient cross-section yet fail mechanically where motion concentrates. Cable routing should control where bending and twisting occur and keep terminations free from unintended load. The permitted movement must come from the actual turbine and cable design.

Cable selection joins electrical performance, installation conditions and termination requirements. A calculation for one purpose does not settle the others. Keep the actual route and equipment interface attached to the design review, so later changes remain visible.

Put these inputs in the review record

Use a project-specific worksheet to capture the following information. For each entry, name the document, revision and person responsible for resolving any uncertainty.

• Range and repetition of bending, torsion or service movement. Identify the exact configuration and the supporting document.
• Cable manufacturer’s motion and environmental ratings. Keep the design assumptions visible in the project record.
• Minimum bend radius, support and strain-relief arrangement. Name the responsible reviewer and resolve any missing information.
• Clearance from edges, hot surfaces and moving components. State how this entry will be verified during acceptance.

Define the acceptance boundary

Require a routing and support detail that demonstrates the intended motion envelope. Do not infer unlimited rotation from a flexible-cable description. If the machine uses twist management or slip rings, document the boundaries that the cable arrangement must respect.

Acceptance photographs should show the movement-critical sections and their supports. Keep these with the approved cable identity so a future replacement preserves both the electrical and mechanical suitability.
