4C 1.5mm² VCTF Copper Wire | Reliable Power & Signal Transmission for Industrial Control

A single intermittent signal fault or a brittle cable jacket cracking inside a cable carrier can halt an entire production line. Procurement managers know this risk well. The 4C 1.5mm² VCTF Copper Wire is engineered to eliminate that weak link. This JIS-compliant, multi-core flexible cable delivers stable power and control signal transmission in light to medium-duty industrial applications. The payoff: significantly reduced unscheduled downtime and a BOM cost that makes sense for volume OEM deployments.

Flexibility That Prevents Field Installation Failures

• 1. Class 2 Annealed Stranded Copper Conductor: The 1.5mm² cores use fine, stranded bare copper formed to Class 2 flexibility. The advantage is a conductor that bends without fracturing under repeated mechanical stress. On your panel-building or machine-tool project, this directly translates to fewer pre-delivery insulation resistance failures and zero post-installation conductor breaks in tight termination enclosures.
• 2. VCTF-Grade PVC Insulation & Sheath Compound: The core insulation and gray outer jacket utilize a polyvinyl chloride compound specifically formulated for VCTF specifications. The advantage is a balance of dielectric strength and physical toughness, without the stiffness found in THW or building wire. For your maintenance team, this means stripping and terminating the cable takes seconds, not minutes—slashing labor hours across hundreds of field connections.
• 3. Four-Core Flat or Round Construction: The 4C configuration bundles three power or two power-plus-earth conductors alongside a dedicated signal or control core in a single jacket. The advantage is simplified BOM management and a single cable pull replacing two separate cable runs. For automated machinery builders, this reduces trunking fill factor and simplifies wiring schematics, lowering the total installed cost per unit.
• 4. Durable Gray PVC Outer Jacket: The jacket resists mineral oil, light acids, and alkalis commonly found on factory floors. The advantage is jacket integrity maintained even when in incidental contact with cutting fluids or lubricants. For a production environment relying on moving gantries or conveyor systems, this prevents insulation embrittlement that leads to costly earth leakage trips.

Where This VCTF Wire Solves Real Engineering Problems

• Automated Machinery & CNC Control Panels: Used for internal wiring of relay racks, sequencers, and operator stations where multi-core flexibility simplifies routing through hinged doorways and crowded ducting.
• Conveyor & Material Handling Motor Connections: Connects fractional-horsepower motors and limit switches where the PVC jacket withstands incidental oil mist and the 300V rating easily handles control-circuit loads.
• Commercial Laundry & Kitchen Equipment: Supplies power to pumps, blowers, and heating-element controls inside equipment enclosures where ambient temperatures are moderate but chemical exposure to cleaning agents is periodic.
• Point-of-Sale & Retail Display Kiosks: Powers lighting ballasts and rotating display actuators where a slim-profile, flexible cable routes cleanly behind removable panels without pinching or kinking.
• HVAC Control Retrofit Projects: Connects damper actuators, VAV box controllers, and zone sensors where pulling two separate cables is impractical. The 4C integration consolidates signal and power, lowering material procurement line items by one-third.

Frequently Asked Questions from Engineering Buyers

Can these 1.5mm² conductors handle a 10A load continuously in free air?
For a typical 3-phase control application at 30°C ambient, 1.5mm² gauge handles approximately 14A–16A in free air. We recommend de-rating to 10A–12A if all four cores are loaded simultaneously inside conduit or trunking. Detailed de-rating tables are included in our batch-specific test report.

We need a cable for moving tracks on an automated packing machine. Is this VCTF rated for continuous flex?
The standard VCTF is intended for static installation or occasional slow-speed repositioning, not continuous high-cycle track-chain or cable-carrier runs. If you require a continuously flexing solution for a moving energy chain, we produce a specific double-insulated version with stranded conductors optimized for bend radii down to 10× diameter. That avoids premature conductor work-hardening on your machine axis.

What is your minimum order quantity for custom-length cuts, and what lead time applies?
Factory-direct standard spooled lengths ship DDP or FOB within 3–5 working days of proforma invoice confirmation. For custom-cut 50m bundles with barcoded traceability tags, the MOQ is normally one full master drum (700m–1000m). This value-added step adds two working days to standard lead times.
