The current transmission loss is 5%-8% lower than that of ordinary oxygen-free copper.

The conductor of the 10mm² submersible cable is annealed, with flexibility improved by 30%, which can withstand repeated bending without breaking, adapting to the working condition of the submersible pump moving up and down.

Regular Cables (1.5mm², 2.5mm², 4mm²): Two insulation options, PVC and XLPE, are provided. PVC Insulation has a lower cost and is suitable for dry indoor environments; XLPE insulation has better temperature resistance (long-term operating temperature 90℃), and its anti-aging performance is twice that of PVC, suitable for humid or large temperature difference scenarios.

Submersible Cable: The insulation layer is EPDM rubber, which has excellent water resistance (water absorption expansion rate ≤5%) and ozone resistance; the sheath layer is made of CR rubber, which is oil-resistant and chemical corrosion-resistant, can withstand acid, alkali, and salt solutions with a concentration of up to 10%, and has a flame retardant grade of UL94 V-0, self-extinguishing when exposed to open fire.

Regular Cables: Available in black, white, and gray. The smooth surface is convenient for threading. The single roll length has two specifications: 100 meters and 200 meters. The reel is packaged with a high-strength hard paper tube, with anti-slip design on the edge, facilitating wire unwinding during construction.

Submersible Cable: Default black sheath (anti-ultraviolet aging), with raised stripes on the surface to enhance friction, facilitating dragging in wet and slippery environments; both ends can be pre-installed with waterproof joints (made of brass nickel-plated) according to requirements, with a joint protection grade of IP68, no additional sealing treatment is required during installation.

Adopting continuous casting-rolling process: Copper ingots are melted at 1200℃, cast into copper rods (diameter 8mm) by a continuous casting machine, and then drawn into the required wire diameter through multiple rolling processes, ensuring the conductor surface is smooth, free of cracks, and the cross-sectional roundness error is ≤0.02mm.

Annealing Treatment: After drawing, the conductor enters a continuous annealing furnace and is softened in a nitrogen-protected atmosphere at 400℃ to eliminate internal stress, improve flexibility, and ensure no "dead folds" when bent.

Regular Cables: Using dry cross-linking extrusion process, the Insulation Material (PVC or XLPE) is melted by a screw extruder and evenly coated on the conductor surface. The extrusion speed is 300 meters per minute, and the insulation thickness deviation is controlled within ±0.05mm to ensure uniform electric field distribution.

Submersible Cable: The insulation layer adopts a three-layer co-extrusion process, with the inner layer being a semi-conductive shielding layer (thickness 0.2mm), the middle layer being an EPDM insulation layer, and the outer layer being a semi-conductive buffer layer. It is formed in one time through a special mold, and the interlayer bonding strength is ≥1.5N/cm to prevent water penetration.

Sheath Extrusion: Using rubber vulcanization extrusion process, CR rubber is bonded with the insulation layer at 180℃, and the vulcanization time is accurately controlled at 3 minutes to ensure the sheath density is ≥1.2g/cm³, without bubbles or pinholes.

Online Testing: Each meter of cable is tested by a spark tester (voltage 10kV), and if there are micropores in the insulation layer, it will alarm immediately; after the finished product, sampling is carried out for water immersion withstand voltage test (3 meters underwater, applying 1.5 times the rated voltage for 1 hour without breakdown).

100 meters/roll: Packaged with a hard paper tube, the inner diameter of the paper tube is 12cm, the outer diameter is 30cm, both ends are sealed with thick cardboard, the outer layer is wrapped with 3 layers of waterproof kraft paper, and then covered with a transparent plastic film for moisture protection. Each roll is labeled with specifications, length, rated voltage, production date, and batch number.

200 meters/roll: Using a wooden reel (diameter 60cm), after the cable is neatly wound, protective plates are nailed on both sides of the reel, on which product information and warning signs (such as "Keep away from fire sources" and "Handle with care") are printed. The center of the reel has a Φ50mm shaft hole, facilitating mechanical handling.

Bulk Packaging: Every 10 rolls of 100-meter packaging or 5 rolls of 200-meter packaging form a pallet. The pallet is made of galvanized steel plate (size 120cm × 80cm). The cable rolls are fixed with strapping tapes, anti-collision corners are added at the four corners of the pallet, and the outer layer is covered with a rainproof cloth.

Standard Packaging: 50 meters/disc, using a high-strength plastic reel (impact strength ≥20kJ/m²). The two sides of the reel have handles for easy manual handling. Both ends of the cable are sealed in waterproof end caps, and the end caps are equipped with waterproof rubber rings to prevent water from entering during storage.

Customized Packaging: For longer lengths (such as 100 meters, 200 meters), steel reels can be used. The surface of the reel is galvanized for rust prevention, and it is equipped with detachable flange plates, which are convenient for recycling after on-site wire unwinding. Each reel is accompanied by a product certificate and an installation manual (including a schematic diagram of waterproof joint assembly).
