5G 6.0mm² 5-Core Copper Cable

A cable failure in a main distribution line doesn’t just interrupt power. It triggers production downtime, rework costs, and potential liability claims from downstream tenants or operators. Resolving these at scale demands a power feeder that doesn’t degrade under continuous rated load and won’t complicate installation with poor phase identification. This 5G 6.0mm² 5-Core Copper Cable addresses that directly. By combining solid copper conductivity with a practical five-core layout, the cable cuts termination time on site while maintaining predictable thermal performance. The result is fewer callbacks and faster project handover.

Consistent Core Identification. No Phase Confusion During Termination

An installation crew working against a deadline can’t afford a wiring error because the cores look identical. This cable uses a standard numeric marking system on each core, making phase identification immediate even in low-light plant rooms. As a result, termination errors drop. That means shorter commissioning checks and a reduced risk of equipment damage from crossed phases.

5-Core Configuration. Single Run Redundancy and Balanced Loads

Pulling two separate cables to support a three-phase load plus a neutral and protective earth adds labor hours and tray weight. The 5G configuration—three phase conductors, one neutral, one earth—bundles the full circuit into one jacket. A single pull replaces two. Less tray congestion, lower installation labor, and a neater, more maintainable electrical room layout.

Solid Copper Conductor. Long-Term Resistance Stability Under Load

Copper-clad aluminum can fail at termination points under thermal cycling due to differing expansion rates. This cable uses solid copper conductors rated at 6.0mm² cross-section. The joint resistance stays stable over thousands of thermal cycles. For a facility manager, that means fewer hot spots, less infrared scanning variance, and no need to re-torque terminals annually after the first energization.

PVC Jacket Formulated for Indoor Infrastructure and Protected Outdoor Conduit

The outer sheath is engineered to resist common industrial contaminants—oils, cutting fluids, and mild alkaline cleaning agents—that break down low-grade cable jackets in months. Combined with reasonable tensile strength, the jacket withstands the physical stress of pulling through conduit bends without tearing. Replacement frequency drops, even in aggressive factory environments.

Industry Applications

• Commercial Building Fit-Outs. Supplies sub-main distribution from floor panels to tenant boards where a full five-wire system is mandated. Reduces the need for separate earth cable pulls in multi-story offices.
• Industrial Machine Power Drops. Connects distribution boards to heavy machinery requiring a clean earth reference. The five-core design isolates the protective earth from the neutral, essential for CNC and sensitive automation equipment.
• Modular Data Center Power. Feeds Power Distribution Units (PDUs) in white-space environments where harmonic currents make a dedicated neutral conductor non-negotiable. The solid copper build handles sustained neutral loading.
• Renewable Energy String Distribution. Links inverter clusters to AC combiners in commercial rooftop solar where a dedicated earth continuity conductor is a safety requirement under local installation codes.
• Temporary Event Power Grids. Powers distribution racks at outdoor exhibitions where rapid deployment and flawless phase rotation matter for rented broadcast and lighting equipment.

International Compliance & QA Standards

• ✅ IEC 60227 / IEC 60228 – Conductor construction and insulation thickness for PVC-insulated cables of rated voltages up to and including 450/750 V.
• ✅ CE Marking – Conformity with applicable EU health, safety, and environmental protection standards for products sold within the European Economic Area.
• ✅ RoHS Directive 2011/65/EU – Materials are tested to restrict the use of hazardous substances including lead and phthalates in insulation and sheathing compounds.
• ✅ ISO 9001:2015 – Manufacturing process quality management covering raw material traceability, in-line dimensional checks, and final electrical testing.
• ✅ Flame Retardance – Sheathing compound design targets compliance with vertical flame propagation testing to reduce fire spread risk in building shafts.

FAQ

What is the difference between 5G 6.0mm² and 5x6mm² cable in terms of the earth conductor?
A 5G cable (where G stands for “with protective earth”) contains a separate earth conductor of a defined cross-section, typically matching the phase cores at larger sizes. This gives a full 6.0mm² earth path. A 5x6mm² notation is often used loosely but may not guarantee the earth core matches the phase core section. If your circuit protection design requires equal PE cross-section, specify 5G to confirm the earth conductor is dimensioned identically to the phase cores.

Can this cable be used for direct burial without additional protection?
The standard PVC outer sheath on this cable is not designed for direct earth burial. It lacks the moisture-blocking, mechanical puncture resistance, and UV stabilization needed for in-ground exposure. For direct burial or outdoor exposed runs, the cable should be installed inside a sealed conduit or trunking system rated for the external environment. For open-tray outdoor use, request a black UV-resistant PVC compound variant.

Is the 6.0mm² cross-section sufficient for a 15kW three-phase motor run over 80 meters?
The suitability depends on the full-load current draw, which varies by motor efficiency and supply voltage (400V vs. 380V). At 400V, a 15kW motor draws approximately 27-28A full load. Over an 80-meter run, a 6.0mm² copper conductor will carry this current, but the voltage drop will be close to the typical 3% guideline for distribution circuits. We recommend calculating the drop using the actual motor power factor and starting current. If the motor starts under heavy load, stepping up to a 10mm² conductor reduces voltage dip and avoids premature contactor drop-out.
