1. Scope and source hierarchy

Classic high flexibility
A 70-row legacy engineering matrix for OZOFLEX H07RN-F, with material codes, current ratings and bending radii.
Round wastewater PLUS
A complete 69-row H07RN8-F engineering matrix with Part/MLFB, dimensions, tensile force and air/water current ratings.
Flat wastewater PLUS
Nine published S07RN8H2-F dimensions and weights.
Screened FC+
Twelve published S07RC4N8-F dimensions, mass and bending-radius records.
Commercial status: legacy material codes and Part numbers are search and traceability references. Current availability and orderability must be confirmed.

4. OZOFLEX H07RN-F detailed construction

OZOFLEX H07RN-F — heavy-duty high-flexibility rubber cable Representative multicore construction; single-core and thin-jacket variants may omit the common inner sheath. 1. Black EM2 rubber outer sheath Weather-, oil-, ozone- and impact-resistant elastomer. 2. Grey EM2/EM3 inner sheath Applied to control cables and thicker multicore jackets. 3. EI4 cross-linked elastomer insulation 4. Bare class-5 copper 5. Green/yellow protective conductor Document-generation caution A 2018 German brochure gives 90°C/250°C, while a separate Nordic product sheet gives 60°C/200°C. Use the exact regional and contractual datasheet.

5. OZOFLEX(PLUS) H07RN8-F detailed construction

OZOFLEX(PLUS) H07RN8-F — round wastewater cable Current-catalogue layer description; the 2016 engineering matrix used a CPE/EM7 outer-sheath description. 1. Black waterproof elastomer outer sheath Current catalogue: EPDM; 2016 matrix description: CPE EM7. 2. Water-resistant EPDM inner sheath Applied where required; reduces formation of water bubbles. 3. EPR insulation 4. Fine-stranded class-5 copper Tinned up to and including 6 mm² in the catalogue description. 5. Protective conductor where specified Water-duty boundary H07RN8-F remains listed at 2,000 m in the 2025 overview; aggressive or unusual water chemistry still requires individual compatibility review.

6. OZOFLEX(FC+) detailed screened construction

OZOFLEX(FC+) S07RC4N8-F — screened wastewater VFD cable Overall-screened construction for converter-fed AC drives; both ends require low-impedance screen bonding. 1. Black CPE outer sheath 2. Tinned-copper overall braid The shield must be bonded at both ends for effective EMC. 3. Water-resistant EPDM inner sheath 4. EPR core insulation 5. Fine-stranded class-5 copper Mechanical and water limits 500 m maximum submersion · 15 N/mm² conductor load · 4D fixed radius · 6D flexible radius · 40°C maximum water temperature.
Screen fault path: the overall braid is not only an EMC component. Its bonding, fault-current capability and termination geometry form part of the electrical protection design.

7. Electrical, mechanical and water framework

PLUS/FC+ voltage
Rated 0.45/0.75 kV; maximum AC 0.476/0.825 kV; maximum DC 0.619/1.238 kV.
PLUS/FC+ test
2.5 kV AC for 15 minutes; motor test 3 kV for no more than three minutes where specified.
PLUS thermal
90°C conductor, 250°C short circuit and 40°C maximum water temperature.
PLUS bending
3D fixed and 4D flexible for unscreened wastewater designs.
FC+ bending
4D fixed and 6D flexible.
Water chemistry
Process, cooling, mine-surface, rain, combined wastewater, groundwater and seawater are referenced, subject to composition review.

The wastewater construction is not simply a thicker H07RN-F. Different sheath systems, water resistance and source generations can produce equal, larger or smaller published dimensions.

16. Engineering selection workflow

Engineering selection workflow 1. Environmentdry / wet / contaminated 2. Geometryround / flat / multicore 3. EMC & firescreen / halogen-free 4. Water systemdepth / chemistry / joints • Use H07RN-F for heavy-duty flexible industrial service, not as an automatic substitute for H07RN8-F. • Use PLUS wastewater variants for permanent immersion; select round, flat or halogen-free construction. • Use FC+ for converter-fed motors and bond the overall screen at both ends with low impedance. • Resolve document-generation conflicts before specifying water depth, sheath compound or conductor temperature. • Qualify the complete system: cable, gland, connector, repair joint, water temperature and chemical composition.

17. Installation and acceptance checklist

  • Confirm exact product: H07RN-F, H07RN8-F, S07HXHX, S07RN8H2-F, S07RC4N8-F or S07HXCHX-F.
  • Confirm round or flat shape, halogen-free requirement and converter/EMC requirement.
  • Use a current detailed sheet for maximum depth, conductor temperature and sheath compound.
  • Qualify the cable, gland, connector, repair joint and pump entry as a complete water-pressure system.
  • Review water chemistry for aggressive or unusual substances.
  • For FC+, bond the screen at both ends with a low-impedance, circumferential termination.
  • Verify conductor resistance, PE continuity, screen continuity and agreed insulation/withstand testing.
  • Record a baseline visual condition and check for sheath swelling, blistering, cracking or chemical attack during inspection.

18. Failure mode and effects analysis

Wrong family: ordinary H07RN-F is treated as a permanent wastewater cable.
Depth conflict: an older 2,000 m statement is used for a product shown at 500 m in the current overview.
Chemical incompatibility: depth compliance is assumed to prove resistance to every wastewater composition.
Accessory leakage: the cable rating is accepted without pressure-qualifying the gland or joint.
FC+ bonding failure: pigtail screen termination creates high impedance and poor EMC.
Thermal mixing: 90°C/250°C values from one H07RN-F document are applied to a 60°C/200°C regional product.
