An aluminum trefoil cable cleat can be priced meaningfully only after the cable envelope, short-circuit duty, proposed fixing spacing, support interface, alloy and finish, liner, documentation and order scope are defined. The quotation should describe one controlled assembly rather than a visually similar catalog size.
Send the outside diameter and tolerance of each single-core cable, trefoil formation, peak short-circuit current and duration, proposed maximum fixing spacing, mounting drawing, aluminum alloy and finish requirement, liner, dissimilar-metal isolation, environment, evidence package, quantity and destination. These are quotation inputs, not a substitute for project approval.
- Best for
- Wind-turbine OEM, EPC, cable-system and procurement teams preparing a comparable RFQ for tower, transition-piece, J-tube or offshore cable routes.
- Not suitable for
- A product rating, a fixed spacing rule, a confirmed price, MOQ or lead time, or proof that an unnamed cleat passed IEC 61914.
- Quotation gates
- cable OD, fault duty, proposed spacing, mounting support, alloy and finish, liner, interface isolation, environment, evidence, quantity and delivery scope
- Information needed
- cable data sheet, short-circuit study output, route and support drawing, fixing details, material specification, document register, quantities and destination
§ 01 Start with the cable envelope, not conductor size
Provide the outside diameter and tolerance of all three single-core cables, jacket material and intended trefoil formation. Conductor cross-section alone cannot define the cavity because cable constructions with the same electrical size can have different overall diameters. State whether one cleat size must cover more than one cable design.
§ 02 Supply short-circuit current and duration from the project study
The buyer should provide the project peak short-circuit current, fault duration, conductor arrangement and calculation reference. IEC 60909 defines methods for short-circuit-current calculation, while IEC 61914 addresses cable-cleat requirements and tests. Neither standard turns an incomplete RFQ into a verified cleat selection.
§ 03 Proposed fixing spacing must include its support condition
State the proposed maximum fixing spacing together with mounting surface, bracket or ladder detail, hole pattern, fastener set and access constraints. IEC 61914 refers to the manufacturer-specified mounting surface, so a report or offer should be checked against the actual support arrangement rather than spacing alone.
§ 04 Define aluminum, finish and dissimilar-metal interfaces
Write the required aluminum alloy or approved equivalence, surface finish, liner and isolation method where aluminum meets stainless or carbon-steel hardware. Marine aluminum corrosion research supports treating alloy condition and protection as design inputs, but it does not certify any cable cleat. Final material acceptance remains project-specific.
§ 05 Separate environmental and document requirements
Identify indoor tower, transition-piece, J-tube, splash, salt-laden or other exposure; also list drawings, material declarations, dimensional records, IEC 61914 evidence, traceability, inspection and packing records. Offshore wind cable research shows that route and loading conditions matter to the cable system, but does not provide a cleat rating.
§ 06 Compare quotations on the same controlled basis
Normalize cable range, fault case, spacing, mounting kit, alloy, finish, liner, fasteners, isolation, evidence, inspection, packaging, quantity, Incoterm and destination. Record every exclusion. A low unit price is not comparable when brackets, hardware or verification documents are outside scope.
Use the wind-turbine cable cleat RFQ template, then compare the proposed spacing with the tower fixing-spacing guide.
| RFQ input | Why it matters | Buyer record |
|---|---|---|
| Cable OD and tolerance | Defines cavity, liner fit and size range. | Cable data sheet and trefoil envelope. |
| Peak current, duration and spacing | Defines the restraint case to review. | Short-circuit study and proposed fixing layout. |
| Support and fasteners | Changes mounting and load transfer. | Interface drawing, hole pattern and hardware schedule. |
| Alloy, finish, liner and isolation | Changes corrosion and interface requirements. | Material and surface specification. |
| Documents, quantity and destination | Changes evidence, inspection and logistics scope. | Document register, quantities and delivery basis. |
Evidence and decision boundary
- Direct evidence
- IEC 61914:2021 covers requirements and tests for cable cleats and intermediate restraints, including declared electromechanical-force resistance and a manufacturer-specified mounting surface. IEC 60909-0 covers short-circuit-current calculation. The cited papers provide wind-cable and marine-aluminum context within their stated scopes.
- Engineering inference
- A quotation is more comparable when cable geometry, fault duty, proposed spacing, mounting, aluminum specification, interfaces, documents and order basis are normalized. This is a procurement inference, not a tested product result.
- Typical or indicative value
- Any early size, spacing, load, price, MOQ or lead-time indication remains provisional until tied to a controlled drawing, relevant tested arrangement and current commercial quotation.
