SZ Stranding Production Line

Loose-tube cable cores · Pay-off to finished core take-up

Bring loose tubes and the specified central member together in a controlled SZ-stranded core. Match tube handling, reversal, binding and water blocking to the cable drawing, then coordinate traction and take-up for the next production stage.

INPUT
Qualified loose tubes, central member and specified filling / binding materials
OUTPUT
Stranded and bound cable core on the agreed package
CORE PROCESS
Pay off → SZ strand → bind / water block → pull → take up
CONFIGURATION BASIS
Tube count, product dimensions, pitch, tension and factory interfaces
SZ STRANDING · COMPLETE LINEHK-800/12 project reference
SZ oscillator equipment reference from the supplied project document
AT THE CORE OF THE PROCESSControlled SZ reversal

Review the stranding head together with tube tension, line speed and binding.

REFERENCE ARRANGEMENTEquipment quantities and final layout follow the reviewed project.

Scope boundary: this line forms the cable core. Loose-tube extrusion, final armoring, aramid reinforcement and jacket extrusion are separate stages unless specifically included in the written scope.

From separate loose tubes to one coordinated cable core.

Define the material entering and leaving the line before choosing machine quantities or a reference model.

01MATERIAL HANDOFF

Start with qualified tubes.

Confirm tube dimensions, identification, supply reels, the central member and any fillers before laying out the pay-off area.

02CORE FORMATION

Coordinate reversal and tension.

Review the SZ lay, reversal sequence and binding requirements against the approved cable-core drawing.

03CORE PROTECTION

Apply the specified package.

Filling compound, binding yarn and water-blocking tape depend on the construction. They are not interchangeable default packages.

04DOWNSTREAM HANDOFF

Deliver a core ready for the next stage.

Agree core geometry, reel build, identification and checks before the core proceeds to its specified sheathing or protection stage.

Configure the line around the core you need to make.

Start with the supply boundary and product mix. Model labels do not replace a review of tube handling, stranding, binding, traction and take-up.

EQUIPMENT IN THIS LINE

SZ oscillator

Alternates the stranding direction to form the prescribed SZ lay around the central member. Coordinate reversal with incoming tube tension, traction and the downstream binding system.

CONFIRM FOR YOUR PROJECT

Tube paths, required pitch, reversal sequence, oscillator movement, line speed and core quality checks.

Selected equipment 05: SZ oscillator

Reference boundary: the panorama illustrates equipment order, not the final machine count, footprint or construction. Images from the project document show equipment families; the approved layout and equipment list define the supplied arrangement.

Compare the complete operating requirement—not one headline speed.

Use a stated cable, material package and test method when reviewing the line. Component limits and net production output are not the same number.

Inputs that determine the SZ line configuration
Review areaWhat to specifyWhy it changes the line
Tube and package rangeTube diameter, tube quantity, supply reels, filler elements and central-member package.Determine the pay-off arrangement and material path.
Core geometryCore diameter, lay, reversal points, binding pitch and geometry after take-up.Define the finished core and its downstream fit.
Water-blocking systemCompound, dry materials, tape / yarn format, application positions and cleaning.Match the material package to the cable design.
Speed and synchronizationRequired stable speed for a stated cable, start/stop behavior and changeover loss.Review the complete line, not one motor or binder maximum.
Reels and handlingInput/output reel dimensions and weight, clamping, lifting and traverse.Specify loading space and the operating sequence.
Controls and acceptanceRecipes, tension signals, alarms, safety interfaces, inspection methods and trial conditions.Make responsibilities and acceptance measurable.
HK-800/12 · REFERENCE, NOT UNIVERSAL LIMITS

Confirm the technical schedule for your cable.

The supplied reference uses 12 loose-tube pay-offs. Final tube range, lay, binding speed, line speed, output drum and installed power belong in the agreed technical schedule—not an assumption based on the model name.

Review My Requirements

See where SZ core formation fits into the cable route.

These published constructions use a stranded loose-tube core. Review the whole solution to understand the stages before and after this line.

Construction matters: a central-tube cable does not automatically require this standalone SZ line. The linked Figure-8 page describes its particular stranded construction, not every cable sold under a similar name.

UPSTREAM EQUIPMENT

Need to produce the loose-tube input first? Review the Loose Tube Production Line.

Watch the process. Define what the trial must demonstrate.

The HONGKAI HK-800/12 video supports a discussion of equipment and operating sequence. It is not a capacity guarantee or an acceptance record for a new project.

01PRODUCT

Trial the specified construction.

Use agreed tubes, central member, binding materials and reels.

02PROCESS

Check coordinated behavior.

Observe pay-off tension, SZ reversal, binding, traction and start/stop sequence.

03OUTPUT

Agree the inspection record.

Confirm core geometry, lay, winding and the required optical or other checks against the written test method.

ACCEPTANCE BASISApproved drawing + agreed materials + operating conditions + written inspection method
Prepare FAT Inputs

Define the support around the equipment—not only the machine list.

The written proposal should connect equipment selection, integration and start-up responsibilities. Confirm the scope with HONGKAI for your project.

01

Equipment scope

  • Specify the supplied modules and quantities
  • Identify retained and buyer-supplied equipment
  • Record equipment-source responsibilities
02

Line integration

  • Review layout and material-flow interfaces
  • Define controls, utilities and safety boundaries
  • Agree installation and commissioning scope

Tell us about the core you need to produce.

Start with your drawing, product requirements or existing equipment. Technical details can be confirmed during the first review.

Questions before specifying an SZ line.

Review the cable construction, equipment boundary and information needed for a proposal.

01What does an optical cable SZ stranding line produce?

It forms a stranded cable core from qualified loose tubes and the specified central member, with the binding and water-blocking package required by the construction. Final reinforcement, armoring and sheathing are separate stages unless the written scope combines them.

02Which cable solutions can include this stage?

The linked ADSS, Micro Cable and GYXTC8S reference constructions include SZ core stranding. Suitability depends on their actual tube count, core geometry, materials and process requirements. A matching cable name alone is not a compatibility confirmation.

03Is HK-800/12 the only possible configuration?

HK-800/12 is the supplied project reference used to explain the equipment. A proposal must still define the active tube count, input and output packages, oscillator, binding system, controls and required operating envelope. Other configurations require engineering confirmation.

04Are the displayed equipment quantities fixed?

No. The panorama illustrates equipment order and the module list explains its functions. The supplied reference proposal lists 12 tube pay-offs, while the panorama is simplified. Use the approved equipment list and layout to establish quantities.

05Does every construction require compound filling and water-blocking tape?

No. Filling compound, binding yarn, tape and other protection materials are selected from the cable construction and applicable project requirements. Their application positions and equipment must be confirmed together.

06How should production speed be compared?

Use the same cable drawing, materials, pitch, reel package, trial duration and inspection method. Maximum component speeds, stable complete-line speed and net output after changeovers are different measures.

07Can selected machines be integrated into an existing line?

The retained equipment must be reviewed first, including its mechanical condition, control signals, line direction, safety interfaces and available capacity. The proposal then identifies the replacement scope and acceptance boundary.

08What should I send for the first proposal?

Send the available cable drawing, tube and reel information, core construction, production target and factory context. Add the binding and water-blocking requirements if known. Missing details can remain open for the engineering review.
