Choosing cable production equipment is a high‑stakes decision. The right line delivers stable quality, predictable throughput, and a payback window your board can stand behind. The wrong choice locks in extra scrap, chronic downtime, and hidden costs. Whether you’re launching your first plant, upgrading legacy lines, or comparing turnkey partners, use this checklist to pressure‑test vendors with measurable, verifiable criteria.

The 10 must‑ask questions (and how to verify)

1. Compliance and safety: Can you provide complete conformity evidence for our target market?

Why it matters: Legal placement and worker safety depend on conformity to applicable machinery and electrical standards.

What to ask:

• EU: Declaration of Conformity under Regulation (EU) 2023/1230 (with risk assessment and technical file index). If placing before January 19, 2027, confirm applicability of Directive 2006/42/EC.

• Electrical safety: IEC 60204‑1 (or NFPA 79 in North America); functional safety per ISO 13849‑1/IEC 62061.

• EMC: Test reports referencing industrial environments (e.g., IEC 61000‑6‑2/‑6‑4).

  How to verify:

• Review conformity docs and accredited test reports. Cross‑check scope and revision years against official sources like the EU’s page on the Machinery Regulation and the EMC Directive. For example, EU guidance confirms the new machinery regulation timeline in the official overview: see the European Union’s summary in the EU‑OSHA brief on Regulation (EU) 2023/1230 and the Commission page for the EMC Directive 2014/30/EU.

2. Performance at rated products: Will the line hit contract speeds with stable dimensions and controlled scrap?

Why it matters: Nameplate speed is meaningless if the line can’t hold tolerances at that speed.

What to ask:

• Contract line speed by product type (e.g., PVC/PE/XLPE insulation or jacketing; typical conductor sizes) and changeover time targets (material/color/tooling).

• Stability criteria: allowable scrap during heat‑up, steady‑state variation limits, and ramp‑up curve.

  How to verify:

• Require FAT/SAT runs at the contracted product, demonstrating speed and quality at once. Capture evidence in the acceptance protocol with traceable instruments, following best practice such as this practical guide to running a successful FAT.

3. Quality control capabilities: How is dimensional and electrical quality monitored in‑line?

Why it matters: Concentricity, ovality, and wall thickness drive electrical performance, rework, and yields.

What to ask:

• In‑line gauges: thickness and concentricity control; closed‑loop capability and Cp/Cpk baselines at rated speeds.

• Electrical integrity: spark test settings and standards (e.g., IEC 62230 or UL 1581) and downstream HV tests per product standard.

  How to verify:

• Request sample Certificates of Analysis and recent FAT data. Confirm test method anchors align with recognized methods such as the material test methods in the IEC 60811 series. Ensure acceptance criteria map to your product standards (e.g., IEC 60502‑1 for LV cables).

4. Energy intensity and utilities: What’s the expected kWh/kg (or kWh/km), and what utilities does the line require?

Why it matters: Energy is a major operating cost; missing utilities cause delays and unstable quality.

What to ask:

• Energy: indicative specific energy for insulation/jacketing at target throughput; measurement method at FAT/SAT.

• Utilities: OEM tables for power (kVA), compressed air (bar and Nm³/h), water flow and temperature (L/min @ °C), and HVAC guidance.

  How to verify:

• Treat 0.3–1.5 kWh/kg as a reasonable extrusion context range depending on polymer and throughput, then measure at acceptance. This framing aligns with bandwidth analyses summarized by the U.S. Department of Energy’s Plastics & Rubber bandwidth study (2017). Require the vendor to provide utility tables in the proposal and confirm on site.

5. OEE and digital readiness: Can the line feed your MES/SCADA and support clean OEE baselining?

Why it matters: Without trustworthy data, you can’t improve throughput, reduce micro‑stops, or manage quality trends.

What to ask:

• OEE: alignment to standardized definitions (Availability × Performance × Quality) and capture of top loss codes.

• Interoperability: OPC UA tag list (server model), historian mapping, and time synchronization method (NTP or PTP/IEEE 1588).

  How to verify:

• Inspect a sample tag catalog and a data dictionary. Ask for a one‑page diagram of how the line publishes to your plant systems.

6. Secure remote diagnostics: How will remote access be controlled and audited?

Why it matters: Remote service reduces MTTR, but unmanaged access creates cybersecurity risk.

What to ask:

• Controls aligned to IEC/ISA 62443: multi‑factor authentication, encryption, role‑based access, time‑bound sessions, audit logs, and DMZ placement.

• Ownership: who administers accounts and logs; emergency revoke procedures.

  How to verify:

• Review the vendor’s remote support architecture against a recognized quick guide like ISA’s introduction to IEC 62443 security for industrial automation and control systems. Simulate a support session during FAT or early SAT and confirm logs capture the interaction.

7. Integration, layout, and tension control: Will the supplier support whole‑plant planning and line synchronization?

Why it matters: Poor layout, utilities, or tension control causes chronic micro‑stops and dimensional drift.

What to ask:

• Plant layout review covering foundations/anchoring, utilities routing, material flow, and safety zoning.

• Upstream/downstream compatibility: pay‑offs, capstans/caterpillars, take‑ups, and master/slave drive coordination with defined tension windows.

  How to verify:

• Request a layout drawing pack and a tension‑control narrative that explains speed references, feedback, and hand‑off between units. If you want a starting point on whole‑plant scoping, see this overview of a Готовое решение для производства оптического кабеля.

8. Maintenance, spares, and reliability: What are the MTBF/MTTR targets and spare‑parts lead times?

Why it matters: Availability hinges on planned maintenance discipline and prompt spares.

What to ask:

• Preventive maintenance plan (daily/weekly/monthly/annual) and training scope for your team.

• Reliability baselines: MTBF/MTTR by subsystem (drives, heaters, capstans, take‑ups, PLC/HMI) and on‑board diagnostics.

• Spares: critical spares list, minimum on‑site kit, OEM stocking commitments, and lead times for long‑lead items.

  How to verify:

• Bake availability targets into the contract (Availability = MTBF ÷ [MTBF + MTTR]). Confirm documentation, spare catalogs, and training sign‑offs at SAT.

9. Financials: Can you model TCO and ROI with real inputs and sensitivity?

Why it matters: Purchase price is only one line in a multi‑year cost model.

What to ask:

• TCO model covering CAPEX, energy, consumables, maintenance, staffing, scrap/rework, downtime, calibration/QA, licenses, and financing.

• ROI/NPV/IRR scenarios for different automation levels; sensitivity to energy, labor, scrap, and downtime frequency.

  How to verify:

• Tie milestone payments to FAT/SAT performance. Use conservative assumptions and verify vendor inputs during acceptance. For helpful context on the structure of a fiber line cost model, see the fiber‑optic cable production line cost guide.

10. Delivery, acceptance, and training: What does “done” look like at FAT/SAT, and who will be trained?

Why it matters: Clear acceptance criteria prevent disputes and ensure a controlled start‑up.

What to ask:

• FAT plan with calibrated instruments, acceptance thresholds (line speed at product X, concentricity %, wall‑thickness tolerance within standard, spark test no‑break at Y kV, changeover ≤ T minutes, energy ≤ E kWh/kg at S m/min), and exception handling.
• SAT plan for your site conditions, including a ramp‑up curve with scrap ceilings and operator/maintenance training with competency sign‑offs.

How to verify:

• Base your protocol on recognized practice; this practical explainer on running a successful FAT is a good checklist to align teams before travel. Ensure multilingual manuals, spare catalogs, electrical/pneumatic schematics, and post‑start‑up refresher training are included.

Practical example — turning layout and utilities into a plan you can execute

Disclosure: HONGKAI is our product.

Suppose your new fiber line must fit a 60‑meter bay with limited chilled‑water capacity. A typical turnkey engagement starts with a draft layout showing pay‑offs, extruder, cooling troughs, capstans, and take‑up positions, plus a utilities table (kVA, Nm³/h @ bar, L/min @ °C). After a walkthrough, the plan iterates to reroute cable trays, add vibration anchoring for the take‑up, and specify HVAC tweaks to stabilize extrusion temperatures. The acceptance pack then maps each utility to commissioning checks, so during SAT your team verifies flow, pressure, and temperature at the actual connection points before the first product run.

A few pitfalls to avoid

• Signing a purchase order before aligning acceptance criteria. If “speed” or “quality” isn’t quantified, you’ll debate it later on the shop floor.
• Overlooking data ownership and time sync. If the vendor’s PLC timestamps drift or data models can’t be mapped, OEE and traceability will stall.
