The cable's durability also makes it suitable for harsh environments such as coastal areas, where galvanized armour resists corrosion from salt spray.

Copper Conductor: The conductor is made from high-purity electrolytic copper, which undergoes rigorous refining to remove impurities that could impair conductivity. It is stranded, consisting of multiple small Copper Wires twisted together, which enhances Flexibility compared to solid conductors. Stranding also ensures uniform current distribution and reduces the risk of conductor breakage during bending or installation. The conductor may be tinned to improve solderability and corrosion resistance in termination points.

Insulation Layer: The conductor is insulated with cross-linked polyethylene (XLPE), a material chosen for its excellent dielectric properties, thermal stability, and Chemical Resistance. XLPE is cross-linked using either chemical or radiation processes, forming a three-dimensional molecular structure that allows it to withstand high temperatures (up to 90°C continuously) without melting or degrading. The insulation thickness is precisely controlled to meet the 15kv voltage rating, typically ranging from 3mm to 4mm, with additional thickness in critical areas to ensure safety.

Copper Tape Shield: The shielding layer is composed of thin, annealed copper tape, which is flexible and easy to wrap around the insulation. Copper is selected for its high electrical conductivity, ensuring effective grounding and electromagnetic shielding. The tape is applied with a 133% coverage to ensure no gaps, preventing electric field leakage and reducing interference. An adhesive may be applied to the tape to secure it in place and enhance bonding with the insulation.

Inner Sheath: Between the shield and the armour, an inner sheath made of polyvinyl chloride (PVC) or low-smoke zero-halogen (LSZH) material provides additional moisture protection and separates the shield from the armour. PVC is cost-effective and offers good mechanical properties, while LSZH sheaths are preferred in enclosed spaces such as buildings and tunnels, as they release minimal toxic smoke and halogen gases in case of fire, improving safety.

Armour Layer: The armour is constructed from galvanized steel, which undergoes a zinc coating process to resist corrosion. Steel tape armour is formed by wrapping steel strips helically around the inner sheath with overlapping edges, providing a rigid protective layer. Steel wire armour consists of steel wires twisted around the sheath, offering greater flexibility and tensile strength. The choice between tape and wire armour depends on the specific application requirements, such as the need for crush resistance or flexibility.

Outer Sheath: The outermost layer is an outer sheath, typically made of PVC or polyethylene (PE), which protects the armour from environmental damage, including moisture, UV radiation, and chemical exposure. PE sheaths are more resistant to water and chemical attack, making them suitable for underground or submersible applications, while PVC Sheaths offer better flame resistance, ideal for indoor installations.

Reels: For standard lengths (500m, 1000m, or custom lengths up to 2000m), the cable is wound onto heavy-duty wooden or steel reels. Wooden reels are cost-effective and environmentally friendly, suitable for domestic shipments, while steel reels offer enhanced durability for international transport or repeated use. Each reel features flanges with a diameter of 1.2m to 2.5m, preventing the cable from slipping off during handling. The reels are equipped with steel hubs and lifting holes to facilitate movement using cranes or forklifts, and the cable ends are sealed with moisture-resistant caps to prevent water or debris ingress.

Coils: For shorter lengths (50m, 100m, or 200m), the cable is coiled and wrapped in multiple layers of heavy-duty polyethylene (PE) film. This film is UV-resistant and waterproof, protecting the cable from environmental damage during short-term storage or local delivery. Each coil is secured with polypropylene straps to maintain its shape and prevent unwinding, with labels indicating the cable type, length, and batch number.

Palletization: Bulk orders of coils or small reels are secured onto wooden pallets using steel straps. Pallets are shrink-wrapped to protect against dust and moisture, and each pallet is labeled with the total weight (typically 500kg to 1000kg) and the number of units, simplifying inventory management and loading/unloading processes.

Specialized Packaging: For export shipments, cables are packaged in seaworthy containers with additional protective measures, such as moisture-absorbing desiccants and anti-rust treatments for steel reels. Custom packaging solutions are available upon request, including waterproof crates for extremely harsh transport conditions.

Loading and Securing: Reels must be loaded horizontally onto trucks, trailers, or shipping containers to prevent deformation. They are secured using steel chains or ratchet straps attached to the vehicle's anchor points, with wooden blocks placed between reels to prevent movement during transit. Coils are stacked vertically with separators to avoid crushing, and their weight is evenly distributed to prevent vehicle imbalance.

Temperature and Environmental Control: The cable is designed to withstand a wide temperature range (-40°C to 90°C), but extreme temperatures during transportation can affect handling. In hot climates, cables are transported in shaded vehicles or containers to prevent sheath softening, which could cause adhesion between layers. In cold climates, where the cable becomes stiffer, loading and unloading are done carefully to avoid cracking the armour or insulation.

Handling Equipment: Only certified equipment, such as forklifts with reel handlers or cranes with spreader bars, is used to move reels. Operators are trained to handle the cable properly, avoiding sudden impacts or drops that could damage the conductor or insulation.
