Round Multicore Flexible Cables for Industrial and Domestic Use

Currency Cables Round Multicore Flexible Cables are engineered using high-conductivity, electrolytic-grade bright annealed bare copper conductors bunched to Class 5 flexibility standards. Insulated and sheathed with specially formulated in-house PVC compounds, these cables are designed to withstand continuous bending, mechanical vibration, abrasion, and exposure to industrial oils and moisture. Compliant with IS 694 benchmarks, they ensure seamless signal integrity and dependable power distribution in automated production lines, switchboards, machine tools, and dynamic electrical installations.

Features & Key Benefits

Class 5 High-Flex Stranding: Ultra-fine multi-strand copper construction provides superior bend radius and eliminates conductor fatigue in moving applications.

99.97% Pure Electrolytic Copper: Delivers maximum electrical conductivity, minimal voltage drop, and reduced energy loss across long industrial runs.

Oil, Moisture & Abrasion Resistant Sheath: Specially formulated tough outer PVC jacket resists harsh chemical atmospheres, cutting fluids, and surface abrasion.

Flame Retardant (FR/FRLS) Insulation: High oxygen and temperature index properties prevent flame propagation and self-extinguish in fire scenarios.

Distinct Core Identification: Color-coded or numbered cores enable rapid, error-free wiring and termination inside crowded control panels.

Frequently Asked Questions

Our cables utilize Class 5 fine-stranded annealed copper conductors bunched in tight, uniform lay lengths, combined with a flexible PVC bedding and outer jacket. This construction allows the cable to endure repetitive bending, flexing, and vibrational stress inside drag chains, machine tools, and robotic tracks without conductor breakage or sheath cracking.

We offer multiple specialized outer sheath options, including General Purpose PVC, Flame Retardant (FR), Flame Retardant Low Smoke Halogen (FRLS-H), Heat Resistant (HR), and specialized Oil-Resistant PVC for factory shop floors exposed to lubricants, coolants, and chemicals.

For cables up to 5 cores, insulation colors adhere to standard IS 694 coding (e.g., Red, Yellow, Blue, Black, Green/Yellow). For cables with 6 cores and above, cores are supplied with uniform color insulation (usually grey or black) featuring legible, sequential alpha-numeric printing along the entire length, accompanied by a dedicated green/yellow earth core.

These flexible cables are primarily designed for indoor machinery wiring, raceways, cable trays, and conduit runs. If outdoor deployment is required, we supply UV-stabilized weather-resistant outer sheathing. For direct underground burial subject to heavy mechanical loading, we recommend our armoured multi-core control/power cables.

Every manufactured drum undergoes rigorous testing at our Kolkata and Howrah testing facilities, including Conductor Resistance Tests (IS 8130), High-Voltage Spark Testing, Insulation Resistance Tests, and polymer Tensile & Elongation checks to ensure total dielectric integrity and zero operational defects.
