1. Source hierarchy and data status
SOURCE
Direct catalogue data
Construction, voltage, diameter, mass, conductor resistance, capacitance, inductance, ampacity, short-circuit current and published tensile force are retained exactly from the archived matrices.
DERIVED
Calculated engineering values
Power, resistive and impedance-related voltage drop, charging current, charging reactive power and dimensional comparisons are calculated from source values.
INFERRED
Transparent working estimates
A provisional 10D moving-radius estimate and one likely decimal correction are clearly isolated from source data and assigned confidence levels.
Family boundary: PROTOLON(M)-R is an open-cast medium-voltage reeling family. PROTOLON(M) F is a semi-flexible installation cable, while PROTOLON(SB/SB-SAM) is a trailing family. Their mechanical limits and matrices are not interchangeable.
2. Application and reel duty
Confirmed duty: connection of large mobile mining machines such as excavators, stackers, crushers, reclaimers and other equipment operating with monospiral or cylindrical cable reels under high mechanical stress.
System-level design: cable life is controlled by reel torque, acceleration, centre/end feed, guide geometry, S-direction changes, roller pressure, tensile load and accumulated torsion—not by conductor size alone.
3. Standard construction: three split-earth interstices
Topology: three screened phase cores are laid around a central cradle/filler. The protective-earth conductor is divided into three sections occupying all three outer interstices.
4. Integrated fibre optics: two earth sections plus FO
Topology change: the optical unit replaces the third earth section. The FO version therefore has two split-earth sections and one optical element, not three earth sections.
G62.5/125
Multimode. Archived family data reference attenuation below 3.3 dB/km at 850 nm and below 0.9 dB/km at 1310 nm.
G50/125
Multimode. Reference attenuation below 2.8 dB/km at 850 nm and below 0.8 dB/km at 1310 nm.
E9/125
Single-mode. Reference attenuation below 0.4 dB/km at 1310 nm and below 0.3 dB/km at 1550 nm.

5. Seven voltage classes

|---|---|---|---|---|---|
| 3.6/6 | 4.2/7.2 | 5.4/10.8 | 11 | 14 | 14 |
| 6/10 | 6.9/12 | 9/18 | 17 | 14 | 14 |

| 14/25 | 17.3/30 | 22.5/45 | 36 | 14 | 14 |
| 18/30 | 20.8/36 | 27/54 | 43 | 14 | 14 |
| 20/35 | 24.2/42 | 31.5/63 | 50 | 6 | 5 |
20/35 kV coverage is partial: the archived matrix publishes only six standard and five integrated-FO constructions. Larger sections are not extrapolated.
6. Mechanical limits: two document generations
Common design controls: the family overview gives torsion up to ±100°/m and multiple-plane operation. The archived engineering treatment also requires at least 20D spacing at S-direction changes.
7. Materials, standards and environmental properties
Design basis
Based on DIN VDE 0250-813.
Conductors
Plain electrolytic copper, extra-flexible construction in the archived M-R description.
Insulation
PROTOLON high-grade EPR, quality better than 3GI3, with inner and outer semiconductive field-control layers.
Sheath system
EPR inner sheath approximately 5GM3, polyester reinforcement braid and red heavy-duty elastomer outer sheath better than 5GM5.
Thermal
Maximum conductor temperature 90°C; short-circuit conductor temperature 250°C.
Environmental
Oil, ozone, UV, weather and moisture resistance are referenced; no universal numerical water-depth rating is assigned.
Current ratings
Archived table values are referenced to 30°C ambient conditions.
Approvals
Later technical appendices list fire certificates and GOST-R/-K/-B for the family; validity must be checked for the exact supplied construction.
8. Complete standard matrix — 90 rows
The source-value columns are preserved. The final column is a deliberately separate low-confidence working estimate of 10 × Dmax for preliminary reel-envelope calculations.

Interpretation: FO does not always increase the published diameter or mass. Several rows are equal or slightly lower due to a different interstice arrangement and source rounding. Exact dimensions—not a generic FO allowance—must control glands and reel design.

12. Inference and anomaly audit
| Item | Field | Source value | Engineering inference | Confidence | Basis |
|---|---|---|---|---|---|
| 14/25 kV, 3×300+3×150/3, standard | R20 source value | 0.74 Ω/km | 0.064 Ω/km | High | The published value is visually 0.74, while 300 mm² rows in adjacent voltage classes and conductor tables are approximately 0.064 Ω/km. Both values are retained. |
| All rows | Moving bending radius | Not tabulated in the archived M-R matrix | 10 × Dmax working estimate | Low | Used only for preliminary reel-space calculations. The source refers to DIN VDE 0298-3; the exact contractual radius remains controlling. |
| Missing Part numbers | Commercial identifier | Not published | Not inferred | Not applicable | The visible numbering is too sparse and non-sequential to support a reliable reconstruction. |
| 20/35 kV matrix | Large conductor sizes | Only 6 standard and 5 FO rows published | Not extrapolated | Not applicable | Diameter, capacitance and mass are voltage- and construction-dependent; linear extrapolation would not be technically defensible. |
14/25 kV, 300 mm²: calculations in this article use the preserved source value only where explicitly labelled as a source reproduction. Design calculations should use the inferred 0.064 Ω/km only after written confirmation.
13. Engineering selection workflow
14. Installation and acceptance checklist
- Confirm the exact designation, voltage class, standard or integrated-FO topology, earth section and Part number.
- Obtain the contractual Dmin/Dmax, mass, conductor resistance, capacitance, inductance, ampacity and short-circuit current.
- Define reel type, centre or end feed, torque control, acceleration, travel path, guide rollers and S-direction geometry.
- Verify the tensile limit and travel speed from one confirmed document generation.
- For FO, define fibre count/type, factory breakout, splice or connector arrangement, attenuation budget and OTDR baseline.
- Check MV termination compatibility with the exact insulation diameter and semiconductive-layer removal method.
- Verify continuity and termination of every split-earth section.
- Measure conductor resistance, insulation/withstand performance under the agreed procedure and optical insertion loss before commissioning.
15. Failure mode and effects analysis
Reel over-tension
High torque or acceleration transfers excessive force into phase conductors. Control drive torque, ramp time and cable pull.
S-bend too short
Insufficient transition distance increases cyclic strain, core displacement and local sheath fatigue.
Accumulated torsion
Incorrect guide geometry allows twist to build up over repeated cycles. Inspect reel alignment and swivel behaviour.
FO microbending
Local compression or a small guide radius raises attenuation and may create intermittent data faults.
Wrong earth topology
A three-earth termination drawing applied to a 2G+FO cable creates an unsafe or incomplete connection.
Generation mixing
Combining 120 m/min, 25 N/mm² and old archived dimensions without confirmation creates an unqualified operating envelope.
