16mm²: 70–85A (ambient temperature 30°C)

25mm²: 95–110A

High-purity aluminum rods (99.5% purity) are heated and drawn through dies to form strands of specified diameters (0.2mm–4.0mm).

Strands are twisted into conductors using a planetary stranding machine, with lay lengths optimized for flexibility (shorter lays for smaller cross-sections).

Conductors are fed into an extrusion line, where molten XLPE (melting point 120–130°C) is applied under controlled pressure (10–15 bar) to ensure uniform thickness.

Cross-linking is achieved via electron beam irradiation (dose: 8–12 Mrad) or steam curing (180°C for 2 hours), transforming the thermoplastic XLPE into a thermoset polymer with enhanced thermal and mechanical properties.

Insulated conductors are grouped according to configuration (e.g., 4x70+16) and twisted together using a cabling machine. The lay length is computer-controlled to ensure symmetry, preventing uneven stress distribution.

For configurations requiring a messenger wire, the steel or aluminum-clad steel wire is integrated into the bundle during twisting, secured with binder tape to maintain position.

Each cable undergoes on-line testing, including diameter measurement (via laser sensors) and insulation thickness checks (ultrasound).

Off-line tests include thermal cycling (-40°C to +90°C for 50 cycles), impact resistance (10J at 23°C), and weathering (accelerated UV exposure).

Samples from each batch are subjected to long-term performance testing (10,000 hours at 90°C) to validate thermal stability.

Cables are wound onto wooden or steel spools (diameter 600mm–1200mm) with capacities ranging from 200m (4x95) to 1000m (2x16). Spools are labeled with batch numbers, configuration details, and test certifications for traceability.

Wooden spools (plywood flanges, pine core) are used for standard orders, offering a cost-effective solution with good moisture resistance.

Steel spools (mild steel flanges, 5mm thickness) are available for export or reusable applications, with a load capacity of up to 1000kg.

All spools feature a central bore (80mm–120mm diameter) to accommodate lifting equipment and ensure stable rotation during unwinding.

The cable surface is wrapped with UV-resistant polythene film (0.1mm thickness) to shield against dust, moisture, and sunlight during storage.

For long-distance shipping, spools are additionally wrapped in heavy-duty craft paper (120gsm) and secured with steel strapping (19mm width) to prevent unwinding.

Each spool is labeled with:

A certificate of conformity, material safety data sheet (MSDS), and installation guide are enclosed with each spool.

For bulk orders, spools are stacked on wooden pallets (1200x800mm) with a maximum height of 1.8m. Pallets are shrink-wrapped (200μm thickness) and strapped with polyester bands (16mm width) to prevent movement.

Domestic deliveries use trucks with flatbeds or enclosed trailers. Spools are secured with ratchet straps (50mm width) to prevent rolling, with wooden chocks placed between spools for stability.

For PVC-insulated variants (if applicable) or in hot climates (ambient temperature ≥40°C), temperature-controlled trailers maintain internal temperatures ≤30°C to avoid insulation softening.

Export orders are shipped in 20ft or 40ft containers, with spools loaded vertically to maximize space. Pallets are separated by dunnage (pine blocks, 100x100mm) to absorb shocks during transit.

Humidity is controlled with 500g desiccant bags (per 10m³ of container volume) to prevent condensation, which could damage wooden spools or insulation.

For urgent orders (e.g., replacement cables for critical infrastructure), spools are shipped via air cargo, with a maximum weight per package of 300kg to comply with airline regulations.

Spools must be lifted using forklifts or cranes with slings (nylon, 50mm width) positioned under the flanges; direct lifting of the cable is prohibited to avoid insulation damage.

Cables should be stored in covered, dry facilities with a maximum ambient temperature of 40°C and relative humidity ≤75%.

Unloading must be done at a controlled speed (≤5km/h) to prevent impact-related damage to spools or conductors.

Standard configurations (2x16, 4x50, etc.): 500m per variant.

Custom configurations (e.g., tinned conductors, armored 4x95+16): 1000m minimum, with a 15% surcharge.

In-stock items (2x16, 4x25, 4x50): 3–5 business days.

Made-to-order configurations: 10–15 business days (includes material sourcing and production).

Export orders: Additional 7–10 days for documentation (certificates of origin, customs declarations).

Available under EXW, FOB, CIF, or DDP terms, with partnerships with major logistics providers (DHL, Maersk, DB Schenker).

Customers can request preferred carriers; alternative options may incur additional fees.

Once shipped, customers receive a tracking number via email, with real-time updates available through the manufacturer’s online portal.

Delivery notifications are sent 24 hours prior to arrival to facilitate receipt and unloading.

Standard samples (1m lengths) of 2x16, 4x50, and 4x70+16 are available free of charge, with a maximum of 3 samples per customer.

Custom samples (e.g., flame-retardant 4x95) are provided for a fee (\(150–\)300, depending on configuration), refundable upon placement of a bulk order (≥5000m).

Standard samples are shipped within 2 business days via express courier (DHL, FedEx), with tracking provided.

Delivery time: 3–5 business days for domestic orders; 7–10 days for international destinations.

Each sample includes a 1m cable segment, a technical data sheet, and a certificate of analysis (testing results for insulation resistance and conductor purity).

A 40-page installation manual (available in English, Spanish, French, and Mandarin) is provided with each order, covering: pole mounting, tensioning, termination techniques, and safety protocols.

On-site technical support is available for large projects (≥10,000m) at a rate of $800/day per engineer, including travel and accommodation.

All cables come with a 10-year warranty against manufacturing defects, including insulation breakdown, conductor corrosion, or premature failure under normal operating conditions (≤90°C, 50m spans).

Warranty excludes damage from improper installation (e.g., over-tensioning), natural disasters (lightning, floods), or unauthorized modifications.

Defective cables identified within the warranty period are replaced free of charge, with the customer responsible for returning the faulty product (shipping costs covered by the manufacturer).

For out-of-warranty issues, repair kits (insulation sleeves, conductor splices) are available for purchase, with online tutorials guiding DIY repairs.

Annual training workshops are held at regional hubs (e.g., Dubai, Houston, Singapore) for utility engineers, covering cable maintenance, troubleshooting, and lifecycle management. Workshops include hands-on sessions with cable testing equipment.

Customized training (e.g., for rural electrification teams) can be arranged on-site, with a focus on low-resource installation techniques.
