A wind turbine cable cleat RFQ should help the supplier size the cleat, check IEC 61914 restraint duty, choose the right material and prepare the document package without repeated clarification emails. The best RFQ is not long; it is complete in the few fields that control design risk.

For a wind turbine cable cleat RFQ, include cable OD, cable formation, peak/RMS short-circuit current, support spacing, mounting detail, installation zone, corrosion class, preferred material, liner requirement, certification needs, quantity and delivery target.
- Best for
- Procurement, electrical and project teams preparing RFQs for tower, nacelle, transition-piece or offshore cable cleat packages.
- Not suitable for
- Replacing project electrical calculations; the fault-current basis and final spacing still need approval by the project designer.
- Selection steps
- 1 — Cable data -> 2 — short-circuit duty -> 3 — spacing and mounting -> 4 — environment and material -> 5 — documents and delivery
- RFQ information
- Cable OD, formation, kA peak/RMS, spacing, mounting, zone, corrosion class, material, liner, quantity, certificates
§ 01 Start with cable and route data
The first line of the RFQ should identify cable outside diameter, single-core or multi-core arrangement, trefoil bundle size and the route: tower vertical run, nacelle exit, transition-piece section or J-tube area. Link this decision back to the wind-energy clamp hub so the supplier understands the application, not only the product name.
§ 02 Add short-circuit duty before asking for price
IEC 61914 selection depends on the prospective short-circuit force, not on appearance. Provide peak current, RMS current, duration and planned support spacing. If the electrical team has not released final values, state the design assumption and ask the supplier to quote with that assumption clearly shown.
§ 03 Define the mounting detail
A cleat body that fits the cable can still fail the installation if the mounting hole pattern, rail width, tray plate or bracket thickness is missing. Send a simple drawing or photo of the mounting surface and state whether stainless fasteners, washers or isolation parts are required.
§ 04 Choose material by environment
Use SS316 or 316L for offshore, transition-piece and exposed chloride zones. Aluminum can be suitable for tower-internal and onshore routes when weight and installation speed matter. For a direct comparison, review SS316 vs aluminum trefoil cable cleats before releasing the RFQ.
§ 05 Request documents with the quotation
Ask the supplier to return a dimensioned drawing, material statement, fastener grade, liner material, installation note and any IEC 61914 test or design basis. For offshore projects, add EN 10204 3.1 material certificates or project-specific inspection documents where required.
§ 06 Use a table format to reduce mistakes
A tabular RFQ helps avoid missing one cable size or mixing routes. List each cable OD and route as a separate row with quantity, material preference, spacing and document requirements. This also lets suppliers quote SS316 and aluminum options side by side.
| RFQ field | Why it matters |
|---|---|
| Cable OD / bundle size | Controls the cleat body size and liner fit. |
| Short-circuit current | Defines IEC 61914 restraint duty. |
| Support spacing | Changes force per cleat and installation quantity. |
| Environment | Drives SS316, aluminum, fastener and liner choices. |
| Documents | Prevents rework during project approval and incoming inspection. |
For floating offshore routes, pair this checklist with dynamic cable-cleat RFQ and inspection data before approving the replacement or new-build package.

Evidence and decision boundary
- Direct evidence
- IEC 61914 provides the relevant test framework. ISO 3506-1 and ISO 9227 define narrower fastener and corrosion-test scopes; they do not replace a configuration-specific cleat report.
- Engineering inference
- A useful RFQ links cable data, short-circuit duty, support spacing, installation geometry, environment, documents and acceptance criteria. Missing inputs should be marked open rather than replaced with assumed values.
- Typical or indicative value
- Suggested RFQ fields and document lists are procurement aids, not guaranteed product ratings or mandatory clauses for every project.
