Outer sheath: Weather-resistant polyvinyl chloride (PVC), with acid and alkali resistance conforming to GB/T 2951 standard, and a low-temperature embrittlement temperature of ≤-25℃.

Conductor stranding: A regular stranding method is adopted, with a pitch ratio of 12-16 times, ensuring the roundness of the conductor and reducing the skin effect;

XLPE insulation extrusion: Three-layer co-extrusion technology is used, with an insulation thickness deviation of ≤±0.1mm, and no defects such as bubbles and scorched particles;

Armoring forming: Steel wires are spirally wound, with a pitch of 20-30 times the diameter and an overlap rate of ≥15%, ensuring the armor layer is uniform and tight;

Sheath extrusion: An extrusion die is used, with a thickness of ≥1.8mm, which is closely attached to the armor layer without delamination risk.

Double protection: XLPE insulation + galvanized steel wire armoring form a "electrical insulation + mechanical protection" double guarantee, which can not only isolate current leakage but also resist external mechanical damage;

Environmental tolerance: It can adapt to various laying environments - it can withstand 300N/cm² soil pressure when directly buried underground, can withstand slight friction when laid in pipes, and has a wind load resistance of ≥0.5kN/m when laid overhead;

Long-life design: The Copper Conductor is treated with anti-oxidation, the anti-aging performance of XLPE insulation is ≥40 years, the anti-rust life of galvanized armor is ≥20 years (underground environment), and the overall design life is ≥30 years.

Industrial field: Power Lines in factory workshops, power supply for production line equipment, and power supply systems for industrial robots;

Municipal engineering: Urban power grid transformation, power transmission in underground pipe corridors, and main lines for street lamp lighting;

Energy facilities: Grid-connected lines of photovoltaic Power Stations, cables in wind turbine towers, and outgoing lines of substations;

Special environments: Humid basements, dusty workshops, and slightly corrosive factory areas (such as sewage treatment plants).

Roll packaging: The length of each roll is 50m, 100m, and 200m according to different specifications (the maximum roll length of 3X95mm² is 100m), using wooden reels for packaging. The reel diameter is Φ600-1200mm, and the load-bearing capacity is ≥500kg;

Reel structure: The side plate thickness is ≥18mm, the axle diameter is ≥100mm, and it is equipped with a steel flange, which can be adapted to the pay-off frame for hoisting;

Protective measures: Both ends of the reel are wrapped with waterproof film, the outer layer is covered with a woven bag, and a specification label (including model, length, production date, and quality inspection number) is pasted on the reel body.

Product label: Including model specification, rated voltage, length, execution standard (GB/T 12706), and production batch number;

Warning signs: Printed with "fragile", "moisture-proof", "up" and other diagrams, as well as hoisting position marks;

Certificate of conformity: Attached with a paper certificate of conformity, indicating the inspector number, delivery date, and warranty period.

Loading: Transport by flatbed truck or container. When the reels are placed flat, the number of stacking layers is ≤2 layers (the load-bearing capacity of the bottom reel is ≥ the total weight of the upper layer). When placed vertically, they must be fixed to prevent rolling;

Transportation restrictions: Avoid severe bumps (acceleration ≤3g), keep away from open flames and high-temperature sources (distance ≥10m), and cover with rainproof cloth when transporting in rainy days;

Loading and unloading: Use a forklift or crane. When hoisting, hook the special lifting holes of the reel flange. Do not directly lift the steel wire armor layer.

Storage environment: A well-ventilated and dry warehouse with a temperature of -10℃ to 40℃, a relative humidity of ≤75%, and away from corrosive gases;

Stacking requirements: The reels are ≥10cm above the ground, with a spacing of ≥30cm, avoiding direct sunlight;

Storage period: The shelf life of unopened products is 18 months. If it exceeds the period, the insulation resistance (≥500MΩ·km) must be re-inspected before use.

Order confirmation: Confirm the specifications, quantity, and delivery date within 24 hours after receiving the order, and arrange production after paying the advance payment (≥30%);

Production cycle: 3-5 days for conventional specifications, 7-10 days for customized lengths, and 15-20 days for bulk orders (≥10km);
