Transmission line hardware projects often require connection plates with specific geometries, hole patterns, thicknesses, and mechanical performance requirements. Standard catalog dimensions may not match every utility's design.
YOKELINK supports drawing-based manufacturing for customized Yoke Plates, helping customers translate engineering requirements into manufacturable components.
Customization options include:
Plate geometry: Triangular, rounded-end, multi-hole, and drawing-specific profiles.
Dimensions: Overall length and height, plate thickness, hole spacing, hole diameter, and edge radius.
Material: Carbon steel grades selected according to the approved design and mechanical requirements.
Surface treatment: Hot-dip galvanizing according to specified coating requirements.
Mechanical performance: Production and testing requirements defined by the customer's drawing and approved technical specification.
Order quantities: Requirements assessed according to design complexity, production process, tooling needs, and order volume.
Customers can submit PDF drawings, CAD files, dimensional sketches, or technical specifications for review before quotation.
YOKELINK evaluates each custom order according to its geometry, manufacturing process, material requirements, coating specifications, and inspection criteria. Depending on the part design, production may involve raw material preparation, profile cutting, hole punching or drilling, edge finishing, dimensional verification, hot-dip galvanizing, and final inspection. The manufacturing route is selected according to the approved drawing and production requirements rather than applying the same process to every plate design.

YOKELINK provides drawing-based manufacturing and replacement solutions for steel Yoke Plates used in overhead transmission line hardware assemblies. Our team can review customer-specified products from established manufacturers, including PLP, Hubbell / ANDERSON, and MacLean Power Systems, to assess dimensional compatibility, material requirements, mechanical performance, and manufacturing feasibility.
Rather than relying on product appearance or nominal strength alone, YOKELINK evaluates each replacement request against the original manufacturer's catalog data, engineering drawings, connection configuration, and project-specific acceptance criteria.
Dimensional Matching: Review plate thickness, overall dimensions, hole diameter, hole spacing, edge radius, and mounting configuration.
Material Selection: Manufacture according to the approved material grade and mechanical requirements.
Surface Treatment: Provide hot-dip galvanized finishes according to the specified coating requirements.
Mechanical Testing: Arrange load testing according to the agreed test method and acceptance criteria.
Quality Inspection: Verify critical dimensions, hole finishing, coating thickness, and required inspection documentation.
Drawing-Based Production: Support custom designs and project-specific power line hardware requirements.
Send YOKELINK the original part number, manufacturer, dimensional drawing, or a sample photograph with key measurements. We will review the available technical information and determine whether a dimensionally compatible replacement can be manufactured.
Quality assurance is essential for power line hardware because connection plates must meet specified dimensional and mechanical requirements in service.
YOKELINK's inspection plan can be tailored to the product drawing, purchase order, and applicable project specifications.

Critical dimensions are checked against the approved drawing, including overall height, plate thickness, hole diameters, hole center distances, edge radii, and hole positioning.
Hole finishing is also checked where required to confirm that the specified chamfers are present and burrs are removed.
Material documentation and identification can be reviewed against the agreed material grade and purchasing requirements. Where specified, material certificates can be included in the inspection documentation.
The galvanized finish is assessed against the agreed coating specification. Depending on the order requirements, inspection may include visual examination, zinc coating thickness measurement, and checks for coating defects or incomplete coverage.
For the illustrated product, the supplied drawing specifies an average zinc coating thickness of at least 86 μm. The applicable acceptance method and sampling requirements should be agreed before production.
Mechanical testing can be conducted according to the agreed test method, loading arrangement, and acceptance criteria.
For the illustrated YOKELINK Yoke Plate specification, the reported breaking load is 135 kN. This value should be associated with the relevant test sample, configuration, and test record; it should not automatically be applied to every Yoke Plate design.
Where requested, the inspection package can include dimensional inspection records, coating thickness results, material documentation, and mechanical test reports, subject to the agreed order requirements.

Yoke Plates are connection components used in overhead transmission line hardware assemblies. Depending on their geometry and approved engineering design, they may connect multiple insulator strings or other associated fittings and help transfer mechanical loads through the assembly.
Typical applications include:
Overhead power transmission line hardware assemblies
Strain and dead-end insulator string assemblies
Multi-string insulator connection arrangements
Customized electrical utility hardware assemblies
Transmission tower and conductor connection systems
Important: The correct plate configuration, connection arrangement, and mechanical rating must be verified against the project's engineering drawings and hardware assembly design.
YOKELINK works from customer drawings and technical specifications to manufacture yoke plates with the required geometry, hole arrangement, thickness, and finish.
Manufacturing operations are selected according to the design and order requirements, helping coordinate cutting, hole processing, edge finishing, galvanizing, and final inspection.
Where required, load testing can be arranged against agreed test procedures and acceptance criteria. The supplied product specification includes a reported breaking load of 135 kN.
Coating requirements are incorporated into the production and inspection plan to support corrosion protection for outdoor transmission line hardware.
YOKELINK supports technical clarification, drawing review, quotation preparation, production coordination, inspection documentation, and export order arrangements for international customers.
Customers can discuss drawing-specific dimensions, material grades, coating requirements, packaging, inspection plans, and documentation before placing an order.

A typical production workflow for a custom Yoke Plate may include:
Drawing Review — Confirm dimensions, tolerances, material, hole layout, coating requirements, and mechanical acceptance criteria.
Material Preparation — Select and verify the agreed carbon steel material.
Cutting and Hole Processing — Produce the plate profile and holes according to the approved drawing.
Edge Finishing — Remove burrs and complete specified chamfers and edge finishing.
Dimensional Inspection — Check critical dimensions and hole positions.
Hot-Dip Galvanizing — Apply the specified zinc coating.
Final Quality Inspection — Review dimensions, surface condition, coating thickness, and required documentation.
Mechanical Testing and Dispatch — Conduct specified testing, review the results, and prepare the order for shipment.
The exact process and inspection stages depend on the approved manufacturing route and purchase requirements.
