PV1-K Flexible Power Cable: Built for Dynamic Industrial Routing

Cable failure in a moving application doesn’t just stop production. It triggers a chain of unplanned maintenance, safety inspections, and warranty disputes that erode margin across the project lifecycle. The PV1-K cable eliminates this failure point. Designed for installations where constant flexing, tight bend radii, and UV exposure destroy standard power cables within months, this single-core flexible cable delivers predictable performance in conduit, tray, and underground raceway systems. The result is fewer callbacks and a longer mean time between replacements.

Conductor Metallurgy Designed for Cyclic Loading

Tinned copper, Class 5 flexibility
Fine stranding absorbs the mechanical stress of vibration and repeated bending without work-hardening the copper.
This means fewer micro-fractures over time. The conductor doesn’t snap under fatigue. For your panel shop or field team, that directly reduces termination failures and the cost of pulling replacements through confined raceways.

TRU-TOUGH XLPE Insulation Against Dielectric Drift

Electron-beam cross-linked polyethylene compound
Thermal stability holds at 120°C under load. Dielectric strength remains consistent after thousands of thermal cycles.
Standard PVC softens. XLPE doesn’t. The critical advantage here is insulation integrity under fault conditions. You get short-circuit temperature ratings up to 250°C without layer deformation—critical for circuits that cannot afford insulation collapse during a downstream trip event.

UV and Water Immersion Resistance Without Secondary Jacketing

Inherently sun-resistant insulation formulation
No LSZH jacket required for outdoor exposure. Tested for 720 hours of accelerated UV weathering with less than 15% tensile strength loss.
This removes one component from your bill of materials. No jacket means a tighter bend radius, faster installation in conduit, and no delamination risk in permanently wet underground ducts. Procurement teams save on SKU complexity and inventory carrying cost.

Flame Propagation Controlled at the Material Level

IEC 60332-1-2 compliant, halogen-free formulation
In a vertical flame scenario, the cable self-extinguishes within 425 mm. Smoke opacity stays low. Emissions are non-corrosive.
For any installation inside a building envelope, this is non-negotiable. Panic hardware, extraction fans, BMS sensor wiring—these circuits must remain functional long enough to execute emergency protocols. PV1-K doesn’t compromise the evacuation window with dense, acidic smoke.

Technical Specifications

Industry Applications

• Solar farm DC string wiring. Withstands 1.5 kV DC bias and daily thermal swing from pre-dawn to peak irradiance without insulation creep.
• Machine tool power chains and cable tracks. Class 5 stranding survives millions of flex cycles inside drag chains on CNC and injection molding lines.
• Underground rail and metro auxiliary power. Halogen-free construction and water-blocking capability make this suitable for tunnel lighting and ventilation circuits subject to permanent high humidity.
• Wastewater treatment plants. Rated AD8 for continuous submersion in aerated grit chambers and chemical dosing zones where hydrogen sulfide and humidity destroy standard building wire within two years.
• Battery energy storage interconnect (DC-side). High thermal headroom (120°C continuous) accommodates the heat buildup inside containerized BESS enclosures without derating.

FAQ

Can PV1-K be installed directly in concrete without conduit?
No. The cable lacks a mechanical protection layer. For embedment in concrete, it must be run inside a suitable conduit or enclosed raceway. Crush resistance of the single-layer XLPE insulation is not rated for direct concrete pour pressure or aggregate abrasion during compaction.

What’s the minimum bend radius I should specify on the drawings?
Four times the cable outer diameter during installation. For fixed routing after installation, you can go tighter—three times the OD—provided no mechanical tension remains on the bend. Pushing beyond 3D risks micro-cracking the insulation’s inner radius, which won’t show on a 500 V megger test but will eventually lead to partial discharge failure under DC load.

Does the “no external sheath” design create problems during cable pulling?
It requires a slightly different handling discipline. The XLPE surface has a higher coefficient of friction than nylon-jacketed cables. We recommend water-based pulling lubricant in metallic conduit runs longer than 20 meters. The upside: you save 15-20% on outer diameter compared to a sheathed equivalent, which buys back cross-sectional space in congested tray layouts.
