High-purity copper is chosen for its superior conductivity, which minimizes energy loss. Annealing at 400-500°C softens the copper, making it easier to strand and reducing the risk of cracking during bending. The stranded design increases flexibility compared to solid conductors, particularly important for installations requiring tight turns.

PVC insulation is a cost-effective choice with good electrical and mechanical properties. It is compounded with phthalate-free plasticizers to enhance flexibility (especially in cold temperatures) and heat stabilizers to resist degradation at 70°C. The insulation is color-coded for phase identification: brown (L1), black (L2), gray (L3), blue (neutral), and green/yellow (earth), ensuring correct installation.

Galvanized steel provides robust mechanical protection. The zinc coating acts as a sacrificial anode, preventing rust and extending the cable’s lifespan in humid or underground environments. Steel tape armouring is preferred for its flexibility and uniform coverage, while steel wire armouring offers higher tensile strength for applications requiring additional pull resistance.

The outer PVC sheath is formulated with a high molecular weight resin to enhance impact resistance. UV stabilizers (such as carbon black) protect against sunlight-induced degradation, making it suitable for outdoor use. The sheath’s smooth surface reduces friction during installation, easing pulling through conduits or trenches.

The cable has a round, compact design with conductors twisted together to form a stable core. The armouring is applied directly over the Insulated Conductors (with a thin inner liner to prevent abrasion), followed by the outer sheath. This layered structure ensures each component performs its function without compromising others.

Color coding of conductors simplifies installation, with the green/yellow striped earth conductor (where included) clearly distinguishable from phase and neutral conductors. The outer sheath is typically black, providing a neutral appearance suitable for various environments.

Wire Drawing: Copper rods (8mm diameter) are drawn through diamond dies to reduce their diameter to 1.04mm (for 6mm²) and 1.2mm (for 8mm²). This process increases tensile strength while maintaining conductivity.

Annealing: The drawn wires are annealed in a continuous furnace under a nitrogen atmosphere to relieve internal stresses. Annealing temperatures range from 400°C to 500°C, softening the copper for easier stranding.

Stranding: Wires are twisted together in a planetary stranding machine to form 6mm² and 8mm² conductors. The stranding lay length is 16-20 times the conductor diameter, ensuring uniformity and flexibility.

Each conductor is fed into an extrusion line where PVC insulation is applied. The PVC compound (resin + plasticizers + stabilizers) is melted at 160-180°C and extruded over the conductor using a cross-head die, forming a uniform layer 0.8mm thick.

Cooling: The insulated conductor is cooled in a water bath to solidify the PVC, ensuring dimensional stability.

Color Coding: During extrusion, pigments are added to the PVC compound to achieve the required phase colors (brown, black, gray, blue, green/yellow).

Insulated conductors are gathered and twisted together in a cabling machine to form the multi-core structure. For the 4X6mm² + 1X8mm² configuration, the 8mm² earth conductor is integrated into the twist. A small amount of filler (polypropylene rope) is added to ensure a round core, facilitating uniform armouring.

Steel Tape Application: Galvanized steel tape (0.3mm thick) is unwound from reels and spirally wrapped around the cabled core with a 15-20% overlap. The tape is formed to match the core’s diameter using forming rollers, ensuring a tight fit.

Steel Wire Application (if used): Galvanized steel wires (1.2mm diameter) are helically wrapped around the core using a rotating head, with a lay length of 12-16 times the core diameter. Tension is carefully controlled to avoid damaging the insulated conductors.

The Armoured Core is fed into a second extrusion line for application of the outer PVC sheath. The sheath compound (with UV stabilizers) is melted at 170-190°C and extruded over the armouring, forming a 1.2mm or 1.4mm thick layer.

Cooling and Sizing: The Sheathed Cable is cooled in a water bath, and a sizing die ensures the outer diameter is consistent. The surface is smoothed to remove imperfections.

Conductor Testing: Resistance measurement using a micro-ohmmeter to verify conductivity.

Insulation Testing: Dielectric strength testing (applying 2.5kV for 5 minutes) and insulation resistance testing with a megohmmeter.

Armouring and Sheath Testing: Tensile strength and elongation of the sheath, adhesion between sheath and armouring, and corrosion resistance of the galvanized steel (salt spray test per ASTM B117 for 96 hours).

Dimensional Checks: Verification of conductor size, insulation thickness, armouring coverage, and outer diameter using precision calipers.

The finished cable is wound onto wooden or steel spools, with standard lengths of 100m, 250m, and 500m. Each spool is labeled with product details, batch number, and compliance marks.

Wooden Spools: Used for 100m and 250m lengths. Spools have a diameter of 400mm (100m) and 600mm (250m), with plywood flanges reinforced with steel rings to prevent warping. The cable is secured to the spool with steel strapping to prevent unwinding.

Steel Spools: Used for 500m lengths, with a diameter of 800mm and steel flanges to support the heavier cable weight. Steel spools are reusable, making them cost-effective for large installations.

The cable on each spool is wrapped with a UV-resistant polyethylene film to protect against dust, moisture, and sunlight. This film is permeable to air, preventing condensation buildup during storage.

For long-term storage (over 6 months), a layer of kraft paper is added between the cable and the polyethylene film to absorb any moisture, reducing the risk of sheath degradation.

Each spool features a durable, weather-resistant label with the following information:

Smaller spools (100m and 250m) are palletized on wooden pallets (1200x800mm) with a maximum of 5 spools per pallet. Pallets are shrink-wrapped to secure the spools and protect against damage during transportation.

Road: Flatbed trucks with spool-holding racks are used for short to medium distances. Spools are secured with chains and anti-slip mats to prevent movement during transit. Enclosed trucks are used in rainy or snowy conditions to protect against moisture.

Rail: Railcars with specialized spool cradles are used for long-distance transportation. Spools are spaced to avoid contact, and padding is placed between them to prevent abrasion.

Sea/Air: For international shipments, spools are loaded into shipping containers. Steel spools are secured to the container floor with twist locks, while wooden spools are strapped down. Desiccants are placed in the container to control humidity.

Spools are lifted using forklifts with padded tines or cranes with soft slings (nylon webbing) to avoid damaging the flanges. Never lift a spool by the cable itself, as this can stretch or damage the conductors.

During loading/unloading, the cable end is secured to the spool to prevent unwinding. Spools are placed upright to maintain stability, and never stacked beyond the recommended height.

The cable is transported at temperatures between -20°C and 50°C. In cold climates, spools are wrapped in insulation blankets to prevent the PVC sheath from becoming brittle. In hot climates, reflective tarps are used to avoid overheating, which can soften the sheath.
