When the scope changes

Conductor bunching works with individual wires. Pair twisting works with insulated cores, and cabling assembles cores or pairs. Define the incoming material before choosing the machine family.

Compare reference configurations

Check the differences that matter to your product. Final selection follows a technical review.

Catalogue figures are reference values. Material, product dimensions and the agreed configuration determine operating output and the final technical specification.

What determines the configuration?

Review the choices behind the equipment package.

Bunching & Stranding
Catalogue equipment example; configuration follows your product.
Check two size limits

Individual wire diameter and total conductor cross-section are separate selection inputs. A suitable finished area does not by itself establish that every wire size is compatible.

Define the conductor construction

Flexible bunches and specified concentric strand layers require different process reviews. Share the strand arrangement, lay and material before choosing a stranding method.

Include reel handling

Take-up diameter affects loading and the next operation. Confirm reel dimensions, loading weight and transfer to insulation extrusion as part of the equipment selection.

Check the connections around the machine.

Input, equipment and output must work as one connected process.

Target output to the process

Use the actual conductor and lay when reviewing output; match working hours and handling assumptions across stages.

Define your equipment package

Agree the main machine and supporting items together before comparing proposals.

Specify in the equipment list

  • Bunching or stranding machine for the conductor design
  • Pay-off count and wire tension arrangement
  • Lay range, direction and take-up reel
  • Wire-break detection and machine control requirements

Confirm the related requirements

  • Supply reels, loading weights and handling equipment
  • Upstream drawing or annealing equipment
  • Conductor acceptance requirements and sample run

Compare the proposal, not only the model.

Is the proposed conductor construction demonstrated at your required working conditions?

Use the same product and scope when comparing suppliers.

Conductor constructionCompare the same individual wire size, strand count, total cross-section and lay. Different constructions can require different machine types.A conductor schedule mapped to the proposed bunching or stranding configuration.
Finished conductorAgree the checks for lay, finished dimensions, surface condition and reel winding on the selected product.Representative wire requirements and a recorded trial/inspection plan.
Pay-off & take-upConfirm the number of wire sources, input reels, take-up format and tension-control responsibilities.An itemised handling package and reel compatibility drawings.
Output comparisonEvaluate the agreed conductor at a defined production condition. Rotational speed alone is not finished metres per shift.Output assumptions including loading, reel changes and product changeovers.

What changes the quotationConductor construction, working range, pay-off count, tension control, reel loading and the selected stranding method change the package. Mark tooling, supporting units, site works and services as included, optional or buyer-supplied before comparing prices.

Define a useful equipment trial.

Agree the representative product, incoming material, setup, run conditions, measurements and records before the trial. Confirm the acceptance criteria together; a catalogue maximum is not a guaranteed result for every product.

Equipment questions

Bunching or stranding: where do we start?

Start with the conductor drawing and the intended cable. The construction, individual wire size, required lay and reel arrangement guide the equipment discussion.

Can this be part of a complete line?

Yes. The catalog covers drawing, conductor formation, insulation, cabling and sheathing. We can discuss the equipment combination around your product.

Can an existing conductor process be upgraded?

Share the current machine details, product range and the bottleneck you want to address. Compatibility with upstream reels and downstream equipment should be reviewed before selection.

Can I select a buncher by reel diameter alone?

No. Reel diameter is only one limit. Compare individual wire diameter, strand count, total cross-section, material, lay length and take-up requirements.

Does maximum rotating speed equal production output?

No. Lay length, conductor construction, setup and operating conditions affect achievable output. Agree the production requirement for your actual conductor rather than treating maximum rpm as a daily capacity.
