1. Source hierarchy and record count
2019 standard matrix
60 power, control, screened-pair, combined-control and control+FO records.
60 power, control, screened-pair, combined-control and control+FO records.
2019 E-RTG matrix
17 power records, including nine 3C+2G+FO designs. Eight non-FO rows exactly repeat the standard matrix.
17 power records, including nine 3C+2G+FO designs. Eight non-FO rows exactly repeat the standard matrix.
2019 vertical matrix
27 current records with central support; one additional 2016-only composite row is retained separately.

Variant brochures
Arctic and SMK-200 are separate material/product generations and do not supply a complete compatible matrix.
Arctic and SMK-200 are separate material/product generations and do not supply a complete compatible matrix.
Counting rule: 105 published table records are reproduced. Removing the eight exact standard/E-RTG repetitions leaves 97 unique branch-specific or archival records.
2. Application architecture
Standard CORDAFLEX(SMK) serves high and very high mechanical reeling duty. E-RTG adds application-specific power+FO constructions. The -V branch adds a central aramid support for suspended vertical reeling.
3. Standard 3C + split-PE construction
4. Vertically supported construction
Support termination: the source Fmax is a complete-cable value increased by the aramid support. The support element must be mechanically anchored; conductor-only clamps do not reproduce the rated vertical load.
5. Product generations must remain separate

The FO power design replaces one of the three PE interstices, so the dimensional increase is construction-specific rather than a universal optical allowance.
12. Representative engineering calculations
Three-phase apparent power at 1 kV: S = √3 × U × I
Active power at cosφ 0.9: P = S × 0.9
Resistive voltage drop for 100 m: ΔU = √3 × I × R20 × 0.1 km
Weight of 100 m: mass × 0.1 × g
Free loop diameter: approximately 2 × published moving radius
Conductor tensile reference: 30 N/mm² × electrical copper area
Vertical support residual: published Fmax − conductor tensile referenceThe residual is an engineering comparison only; it is not the rated aramid breaking load.

| Item | Field | Source | Treatment | Basis |

| Standard bus 12x(2×1)C | Part number | Not published | Not inferred | MLFB 5DH3206 is retained; no defensible SAP sequence. |
| E-RTG FO 35, 50, 95, 120 and 300 mm² | Part number | Not published | Not inferred | Published Part numbers are too sparse to reconstruct reliably. |
| Standard 18×1.5 | Diameter | 21.3–23.3 mm | Preserved source anomaly | It is 0.1 mm below the 12×1.5 row. |
| Standard 18×2.5 | Diameter | 23.3–25.3 mm | Preserved source anomaly | It is 0.1 mm below the 12×2.5 row. |
| Vertical 12×2.5+(4×0.5)C | Catalogue status | Present in 2016; absent in 2019 matrix | Archive-only row | Kept separately rather than merged into the current vertical matrix. |
| Vertical supported rows | Support contribution | Fmax minus 30×electrical copper area | Derived | Represents a preliminary residual, not the rated aramid breaking load. |
14. Engineering selection workflow
15. Installation and acceptance checklist
- Confirm exact branch: standard, E-RTG, vertical, Arctic or SMK-200.
- Verify -J/-O, PE topology, screened pair, bus element and optical construction.
- Use the published Dmin/Dmax, moving radius, mass and Fmax for the exact Part number.
- Control reel torque, acceleration, cable guide alignment, roller pressure and S-direction geometry.
- For vertical duty, calculate suspended cable weight and terminate the central support in an approved load-bearing fitting.
- For FO, define count/type, wavelength, optical budget, factory breakout and OTDR baseline.
- For bus elements, verify characteristic impedance, attenuation, termination and protocol-specific segment length.
- Complete conductor resistance, PE continuity, agreed insulation/withstand and optical insertion-loss tests before commissioning.
16. Failure mode and effects analysis
Reel over-tension: torque or acceleration exceeds the 30 N/mm² envelope.
Torsion accumulation: misaligned guides exceed ±50°/m.
Wrong PE topology: a 3G termination is applied to a 2G+FO E-RTG design.
Vertical support bypass: the aramid element is not mechanically anchored.
FO microbending: guide pressure or small radius increases attenuation.
Generation mixing: Arctic or SMK-200 claims are applied to an unverified 2019 Part number.
