Urban Power Grids: The 6/10kv and 12/20kv variants are widely used in city distribution networks. Their single-core design allows efficient routing through underground ducts and concrete trenches, while the "F" (water/corrosion resistance) designation makes them suitable for damp urban environments, such as near rivers or in flood-prone areas. The 240mm² cable is often deployed in residential neighborhoods, while the 300mm² option powers commercial districts with high-density loads.

Industrial Zones: Factories, refineries, and chemical plants rely on the 12/20kv cables for internal power distribution. The "F" variant’s corrosion resistance protects against chemical spills and industrial fumes, while the 300mm² conductor handles heavy machinery loads (e.g., motors, furnaces). In petrochemical facilities, the cables’ fire-retardant properties (enhanced in "FL" models) reduce fire propagation risks.

Renewable Energy Projects: Solar farms and wind parks utilize the 18/30kv Cables to transmit power from generators to grid connection points. The 300mm² conductor minimizes power loss over long distances (up to 10km), while the "FL" variant’s fire resistance is critical for installations in forested or high-risk areas. The cables’ UV-resistant sheaths and temperature tolerance (-40°C to 90°C) ensure reliability in outdoor, exposed environments.

Transportation Infrastructure: Subways, airports, and railway networks depend on the "FL" models for their fire safety. In tunnels, the 12/20kv cables power lighting, signaling, and ventilation systems, with the fire-resistant insulation maintaining circuit integrity for up to 120 minutes during a fire—compliant with EN 50200 standards. The single-core design simplifies installation in narrow tunnel ducts.

High-Rise Buildings: The 6/10kv and 12/20kv cables are used in vertical risers of skyscrapers, where the "F" variant’s water resistance prevents moisture ingress in elevator shafts or utility risers. The 240mm² conductor efficiently distributes power to floors, while the compact single-core design reduces space requirements in crowded building shafts.

Conductors: Constructed from high-purity electrolytic copper (99.95% purity) or aluminum alloy, the conductors prioritize conductivity and corrosion resistance. Copper offers lower resistance (58 MS/m) and is preferred for high-efficiency applications, while aluminum (37 MS/m) provides a cost-effective, lightweight alternative for long-distance installations. Both materials are stranded with a class 2 or 5 stranding pattern to balance flexibility and strength.

Insulation: XLPE is the primary Insulation Material, chosen for its exceptional thermal stability and Chemical Resistance. XLPE is cross-linked via either chemical (peroxide) or radiation curing, forming a three-dimensional molecular structure that withstands 90°C continuous operation. For "FL" models, the insulation is infused with flame-retardant additives (e.g., magnesium hydroxide) to suppress combustion and reduce smoke emission.

Screening: A semi-conductive screen layer is applied over the insulation to control electric field distribution, preventing partial discharges. This layer is typically a carbon-loaded XLPE or EPR tape, ensuring uniform contact with the insulation and minimizing voids that could degrade performance.

Sheath: The outer sheath varies by model: "F" variants use a halogen-free low-smoke (HFLS) polyolefin sheath with anti-UV and anti-rodent additives, suitable for outdoor or damp environments. "FL" models feature a fire-resistant sheath (e.g., modified PVC or ethylene vinyl acetate) that chars to form an insulating barrier during combustion, meeting IEC 60332-3-24 fire resistance standards.

Armoring (Optional): For heavy-duty applications, Steel Tape or wire armor may be added beneath the sheath. Galvanized steel tape armor (STA) resists crushing in underground installations, while steel wire armor (SWA) provides tensile strength for overhead or vertical installations. Armor thickness ranges from 0.8mm to 1.2mm, depending on the cable size.

Reels: For lengths ≥500m, cables are wound onto wooden or steel reels. Wooden reels (FSC-certified) are used for domestic shipments, featuring 1.5–2.5m diameter flanges to prevent slippage. Steel reels, with galvanized frames, are reserved for international transport or reusable applications, offering enhanced durability against rough handling.

Coils: Short lengths (50–200m) are coiled and wrapped in UV-resistant polyethylene film, secured with polypropylene straps. Each coil includes a moisture-absorbing desiccant packet to prevent condensation during storage.

Labeling: Every reel/coil is labeled with the model, specification (conductor size, voltage), length, batch number, and compliance marks (CE, UL, ISO 9001). "FL" models feature additional fire resistance certifications (e.g., CPR Class B2ca).

Palletization: Bulk orders are palletized with non-slip pads, shrink-wrapped, and labeled with gross weight (typically 800–1200kg per pallet) for easy logistics planning.

Loading: Reels are loaded horizontally and secured with steel chains to prevent rotation during transit. Coils are stacked vertically with wooden separators to avoid crushing.

Temperature Control: Cables are transported in covered vehicles to avoid UV exposure. In temperatures <0°C, reels are pre-warmed to 10–15°C to prevent sheath brittleness; in >40°C, ventilation systems maintain <35°C to avoid insulation softening.

Handling Equipment: Forklifts with reel clamps or cranes with spreader bars are mandatory for reel movement. Manual handling is restricted to coils <50kg, with gloves required to prevent sheath damage.

Documentation: Shipping documents include a packing list, certificate of conformity, and material safety data sheet (MSDS). International shipments add customs declarations and voltage compatibility certificates.

Domestic Delivery: Road transport via curtain-side trucks (2–5 business days) for bulk orders; express courier (1–2 days) for urgent small quantities.

International Shipping: Sea freight (3–6 weeks) for full container loads, with FOB or CIF terms available. Air freight (3–5 days) is offered for urgent orders, with door-to-door service via DHL or FedEx.

Tracking: Customers receive real-time tracking via a web portal, with notifications for departure, port arrival, and final delivery.
