High-purity electrolytic copper is chosen for its exceptional conductivity, which minimizes energy loss. The copper is annealed at 400–500°C in a nitrogen atmosphere to reduce brittleness and improve ductility, making it easier to strand and bend without cracking.

Stranded Conductors (class B) enhance flexibility compared to solid conductors, allowing the cable to be routed around obstacles and bent to tight radii during installation. This is particularly important in commercial and residential buildings where space is limited.

Radiation-cross-linked XLPE is preferred over chemical cross-linking for its uniformity and purity. The cross-linking process creates a thermoset material that retains its properties at high temperatures, unlike thermoplastic materials that soften. This ensures the insulation remains stable under overload conditions.

The insulation is color-coded for phase identification: black, red, and blue for phase conductors, and white or gray for neutral conductors, facilitating correct installation in three-phase systems.

The inner PVC sheath is formulated with high flexibility to absorb mechanical stress between the XLPE insulation and outer sheath. It acts as a cushion, preventing abrasion during installation and operation, which could damage the insulation.

This layer is typically clear or white, allowing visual inspection of the XLPE insulation for defects during manufacturing and installation.

The outer PVC sheath is formulated for durability and flame resistance. It contains antimony trioxide, a flame retardant that inhibits combustion by releasing free radicals that disrupt the flame chemistry. Carbon black is added as a UV stabilizer, protecting the sheath from sunlight-induced degradation.

The sheath is typically black, providing a uniform, professional appearance suitable for both indoor and outdoor installations. Black also absorbs heat, which can help dry the sheath in damp environments, reducing moisture absorption.

The cable has a round, compact design with concentric layers: conductor, XLPE insulation, inner PVC sheath, and outer PVC sheath. This layered structure ensures each component performs its function without compromising others.

The overall design is robust yet flexible, allowing for easy handling and installation. The cable’s outer diameter is optimized to fit into standard conduits, cable trays, and gland sizes, ensuring compatibility with existing infrastructure.

Wire Drawing: Copper rods (8 mm diameter) are drawn through diamond dies to reduce their diameter to the required size for individual strands (e.g., 0.52 mm for 10 AWG). This process increases tensile strength while maintaining conductivity.

Annealing: The drawn wires are annealed in a continuous furnace under a nitrogen atmosphere at 400–500°C to relieve internal stresses. Annealing softens the copper, improving ductility and flexibility.

Stranding: Strands are twisted together in a planetary stranding machine at a lay length of 16–20 times the conductor diameter. For example, 10 AWG conductors use 19 strands twisted at a lay length of 8–10 mm. This ensures uniform flexibility and prevents strand slippage.

Each stranded conductor is fed into an insulation extrusion line. The XLPE compound is melted in an extruder at 120–150°C and forced through a cross-head die, applying a uniform layer of insulation around the conductor.

Radiation Cross-Linking: The Insulated Conductor is exposed to an electron beam (10–30 MeV) to cross-link the XLPE molecules. This step is critical for achieving the material’s high-temperature resistance and mechanical strength.

Cooling and Sizing: The insulated conductor is cooled in a water bath to solidify the insulation, and a laser gauge ensures the thickness meets specifications. The conductor is then spooled for the next process.

The insulated conductor is fed into a second extrusion line where the inner PVC sheath is applied. The PVC compound is melted at 160–180°C and extruded over the XLPE insulation, forming a 0.5 mm thick layer.

Cooling: The sheath is cooled in a water bath to solidify, ensuring dimensional stability. A laser gauge checks for uniform thickness, and any defects are corrected before proceeding.

The cable with the inner sheath is fed into a third extrusion line for the outer PVC sheath. The PVC compound (with flame retardants and UV stabilizers) is melted at 170–190°C and extruded over the inner sheath, forming a layer 0.8–1.2 mm thick (depending on conductor size).

Cooling and Sizing: The outer sheath is cooled in a water bath, and a sizing die ensures the outer diameter is consistent. The cable surface is inspected for imperfections, such as bubbles or cracks, which are repaired or rejected.

Conductor Testing: Each conductor is tested for resistance using a micro-ohmmeter to ensure compliance with ICEA S-95-658.

Insulation Testing: Insulated conductors undergo dielectric strength testing (2.5 kV for 5 minutes) and insulation resistance testing (≥1000 MΩ·km) to verify insulation integrity.

Sheath Testing: Tensile strength and elongation of both inner and outer sheaths are tested to ensure they meet mechanical property requirements. The outer sheath is also tested for flame retardancy using a vertical burn test.

Overall Cable Testing: The finished cable is tested for voltage withstand (3 kV for 5 minutes), partial discharge (≤10 pC at 1.73 kV), and bending resistance (10×diameter for 10 cycles).

Dimensional Checks: Outer diameter, insulation thickness, and sheath thickness are measured at multiple points to ensure compliance with specifications.

The finished cable is wound onto steel or wooden spools with diameters ranging from 300 mm (10 AWG) to 800 mm (4/0 AWG), depending on the conductor size and order length. Standard lengths are 100 m, 250 m, 500 m, and 1000 m. Each spool is labeled with product details, batch number, and compliance marks (ICEA S-95-658, UL, etc.).

Steel Spools: Used for larger conductors (1/0 AWG to 4/0 AWG) and longer lengths (500 m, 1000 m). These spools have steel flanges (200–300 mm wide) reinforced with steel ribs to support the cable’s weight. The cable is secured to the spool with steel strapping to prevent unwinding during transportation.

Wooden Spools: Used for smaller conductors (10 AWG to 4 AWG) and shorter lengths (100 m, 250 m). Spools are made from plywood with steel-reinforced flanges to prevent warping. The cable is wrapped with a polyethylene film to protect against dust and moisture.

The cable on each spool is wrapped with a UV-resistant polyethylene film to protect against dust, moisture, and sunlight during storage and transportation. For long-term storage (over 6 months), a layer of kraft paper is added to absorb moisture, preventing condensation buildup.

Spools are labeled with durable, weather-resistant tags containing:

Compliance marks (ICEA S-95-658, UL certification)

Handling instructions: “Store in Dry Area,” “Maximum Stacking Height: 3 Spools,” “Use Forklift at Designated Points”

Smaller wooden spools (10 AWG to 4 AWG) are palletized on heat-treated wooden pallets (1200×800 mm) to meet international shipping standards. Each pallet holds up to 6 spools, secured with stretch wrap and steel bands to prevent movement during transit.

Steel spools (1/0 AWG to 4/0 AWG) are palletized individually due to their weight, with anti-slip pads placed between the spool and pallet to ensure stability.

Road: For short to medium distances, flatbed trucks with spool racks are used. Spools are secured with ratchet straps and chains, with wooden blocks placed between them to prevent friction. Enclosed trucks are used in rainy or snowy conditions to shield the cable from moisture.

Rail: For long-distance domestic transport, railcars with specialized spool cradles are utilized. Spools are arranged to avoid contact, and padding is added to minimize vibration damage during transit.

Sea: International shipments are containerized in 20-foot or 40-foot containers. Steel spools are bolted to the container floor using twist locks, while wooden spools are secured with steel strapping. Desiccants are placed inside containers to control humidity (maintaining <60% relative humidity).

Air: For urgent orders, air freight is available. Cables are packaged in smaller spools (≤250 m) to meet weight restrictions, with foam padding used to protect against impact.

Spools must be lifted using forklifts with padded tines or cranes with nylon slings (minimum width 100 mm) to avoid damaging flanges. Lifting by the cable itself is strictly prohibited, as it can stretch conductors or tear sheaths.

During loading/unloading, the cable end is secured with a plastic cap and tape to prevent fraying. Spools are always transported in an upright position to maintain balance.

The cable must be transported at temperatures between -20°C and 50°C. In cold climates, spools are wrapped in insulation blankets to prevent PVC sheath brittleness. In hot climates, reflective tarps are used to limit exposure to direct sunlight, keeping sheath temperatures below 60°C.
