3 Core 35mm² LAPP ÖLFLEX Power Cable | High Quality

3 Core 35mm² LAPP ÖLFLEX Power Cable – Engineered for High-Load Industrial Distribution

Cable failure in a primary power distribution loop introduces costs that extend far beyond the price of the cable itself. You are looking at unplanned downtime on automated production lines, overtime for re-pulling conductors through congested cable trays, and potential thermal imaging audits to verify adjacent circuits were not compromised. The 3 Core 35mm² LAPP ÖLFLEX Power Cable is specified to eliminate these systemic failure points. It delivers stable, low-resistance power transmission under continuous mechanical stress and harsh environmental exposure. This means a fixed installation lifespan that matches the lifecycle of your machinery, not a consumable replacement schedule.

  • High-Strand Class 5 Flexible Copper Conductor
    Fine-wire stranding increases conductive surface area while maintaining mechanical ductility. This prevents micro-fractures during vibration and repeated bending. Lowers heat buildup at termination points. Directly reduces hot-spot risk in MCC panels and motor junction boxes.

  • Colour-Coded Cores (HD 308 S2)
    Brown, black, grey core identification with a green/yellow protective earth. Immediate phase identification eliminates wiring errors during installation. Cuts commissioning time and prevents costly phase-reversal damage to rotating equipment.

  • Flame Retardant Per IEC 60332-1-2
    Compound-limited flame propagation. The jacket self-extinguishes when the external ignition source is removed. Limits fire spread in densely packed cable bundles. Preserves adjacent circuits in a plant emergency. Essential for insurance compliance in processing facilities.

  • Oil Resistant Outer Sheath
    Special PVC formulation resists degradation from mineral oils, coolants, and cutting fluids common in CNC machining centers and hydraulic press environments. No jacket embrittlement. No premature insulation exposure. The cable survives where standard PVC-sheathed alternatives fail within 12 months.

  • Extended Temperature Performance
    Bench-rated for flexible use from -5°C up to +70°C and fixed installation down to -40°C. Reliable cold-weather handling during outdoor winter installations. No sheath cracking when bent at sub-zero temperatures. Keeps construction schedules intact even in northern latitude projects.

Industry Applications & Scenario Validation

  • Motor Control Centers (MCC) & Main Drives
    Powers high-inertia drives where startup surges demand a cable that can handle thermal cycling without insulation delamination.
  • Industrial Pumping Stations
    Resists water ingression in coastal sump applications, while oil resistance keeps the jacket intact when exposed to pump lubricants and compressor oils.
  • Automated Assembly Lines
    Withstands millions of continuous flex cycles in robotic dress packs, reducing slack management interventions.
  • Building Services (HVAC & Chiller Plants)
    Meets stringent flame propagation limits (IEC 60332) for installation in public infrastructure risers and suspended cable trays.
  • Wind Turbine Nacelles
    Maintains torsional strength during nacelle yaw movements. The class 5 fine wire stranding resists fatigue failure better than rigid Class 1 or 2 conductors.

Frequently Asked Questions

What is the derating factor for this 35mm² cable when installed in a perforated cable tray with 4 circuits?
For a 3-core cable with an ambient temperature of 30°C, the derating is determined by the thermal spacing within the tray. With 4 circuits and standard spacing (one cable diameter between bunches), you should apply a grouping factor of approximately 0.72 to the free-air rating. Do not skip the horizontal separation. The current carrying capacity drops significantly if these go in bundled without air gaps.

How do you terminate a Class 5 flexible conductor into a standard bolted busbar terminal?
You must use a gas-tight compression (ferrule) lug. Do not attempt a direct mechanical set-screw connection on fine-wire strands. The loose strands will relax under heat, creating a high-resistance joint. We recommend DIN 46234 compression lugs sized exactly for the 35mm² cross-section. Crimp with a hexagonal die profile to maintain pull-out strength exceeding 2200 N.

Can this cable be installed directly in sub-zero ground without pre-heating the drums?
Yes, but only for fixed installation. The jacket remains impact-resistant down to -40°C. However, dynamic handling such as pulling through a conduit should not occur at temperatures below -5°C unless the drum is stored in a heated tent overnight. Pulling at extreme low temperatures without conditioning risks jacket surface tearing from the pulling grip.
