Cross-Sectional Area: Available in two sizes, 1.5mm² and 2.5mm². The 1.5mm² conductor is suitable for lower current applications, while the 2.5mm² variant handles higher currents, making it versatile for various power requirements.

Stranding Configuration: The 1.5mm² conductor consists of 16 strands of 0.3mm diameter Copper Wire, twisted in a concentric pattern with a lay length of 12-15mm. The 2.5mm² conductor uses 24 strands of 0.3mm diameter wire, with a lay length of 15-18mm. This stranding design enhances flexibility, allowing the cable to bend easily without damaging the conductors, even after repeated use.

Conductivity and Resistance: The high-purity electrolytic copper (99.9% purity) used in the conductors ensures excellent electrical conductivity of 58 MS/m at 20°C. The DC resistance at 20°C is ≤12.1Ω/km for the 1.5mm² conductor and ≤7.41Ω/km for the 2.5mm² conductor, minimizing energy loss during power transmission.

Insulation Thickness: 0.6mm for both 1.5mm² and 2.5mm² conductors. This thickness ensures a dielectric strength of ≥18kV/mm, preventing electrical breakdown and short circuits even in high-voltage conditions.

Temperature Rating: The insulation is rated for continuous operation at 90°C, with short-term tolerance up to 130°C during overloads. This allows the cable to handle the heat generated by high currents in industrial equipment without degradation.

Thickness: 1.2mm for the 1.5mm² cable and 1.5mm for the 2.5mm² cable. This variation in thickness ensures adequate protection based on the current-carrying capacity and expected usage conditions.

Material: Made from synthetic rubber (EPDM or neoprene), which offers excellent resistance to heat, oil, water, UV radiation, and ozone. This material choice ensures the sheath remains flexible and durable even in harsh environments.

Flame Retardancy: The outer sheath meets EN 60332-1-2 standards, meaning it is flame-retardant and self-extinguishing within 60 seconds of removing the flame source, reducing the risk of fire spread.

Overall Diameter: The 1.5mm² cable has an outer diameter of 7.0mm ±0.2mm, while the 2.5mm² cable has an outer diameter of 8.5mm ±0.2mm. These compact dimensions allow for easy installation in tight spaces and through conduits.

Bending Radius: The cable has a minimum bending radius of 4x the outer diameter for fixed installations and 6x for dynamic applications (where the cable is frequently moved). For example, the 1.5mm² cable has a bending radius of 28mm for fixed use and 42mm for dynamic use, ensuring flexibility without damaging the insulation or conductors.

Conductivity Testing: The electrical conductivity of the Copper Conductors is measured to ensure it meets the 58 MS/m requirement.

Insulation Resistance Testing: A high-voltage test is performed to check the insulation resistance, ensuring it is ≥100 MΩ at 500V DC.

Dielectric Strength Testing: The cable is subjected to a voltage of 3kV for 5 minutes to ensure no breakdown occurs.

Flame Retardancy Testing: Samples are tested according to EN 60332-1-2 to verify flame-retardant properties.

Flexibility Testing: The cable is bent repeatedly around a mandrel to simulate dynamic use, ensuring no damage to the insulation or conductors.

Environmental Testing: Samples are exposed to UV radiation, temperature cycles (-40°C to 90°C), and immersion in water or oil to test resistance to environmental factors.

Safety warnings and handling instructions

Road Transport: For short to medium distances (up to 500km), trucks are the preferred mode of transportation. Reels are loaded onto flatbed or enclosed trailers, with enclosed trailers providing better protection against weather and road debris. Smaller packages (pre-cut lengths) can be shipped via courier services.

Rail Transport: For larger quantities and longer distances within a country or continent, rail transport is efficient and cost-effective. Reels are loaded into railcars, secured to prevent movement during transit.

Sea Transport: For international shipments, sea freight is used. Reels are packed into shipping containers, with dunnage (wooden blocks) and straps to secure them and prevent shifting during the voyage. Humidity-absorbing packets may be included to protect against moisture in containerized transport.

Air Transport: For urgent shipments or small quantities, air freight is available, though it is more expensive. Small reels and pre-cut lengths can be shipped via air, with strict weight and size restrictions.

Reels are placed on a flat surface and spaced to avoid contact with each other, reducing the risk of abrasion.

Straps or chains are used to secure the reels to the transport vehicle, with tension applied evenly to prevent tilting or movement.

For sea transport, reels are secured using blocking and bracing, which involves placing wooden blocks around the reels and securing them to the container walls.

Reels should be lifted using appropriate equipment, such as forklifts with reel handlers or cranes with slings, to avoid damage to the reel flanges or the cable.

Reels should be moved vertically (with the flange faces horizontal) to prevent the cable from unwinding or becoming tangled.

Dropping or dragging reels is strictly prohibited, as this can damage the cable's outer sheath and internal conductors.

During loading and unloading, care should be taken to avoid sharp objects that could puncture the cable's sheath.

Enclosed trailers or containers are used to shield the cable from rain, snow, and UV radiation, which can degrade the rubber sheath.

In cold weather, precautions are taken to prevent the cable from becoming brittle, such as avoiding exposure to temperatures below -40°C for extended periods. If necessary, heated trailers can be used.

In hot weather, ventilation is provided to prevent overheating, which could cause the rubber to soften and lose its shape.

Check the reel for damage (e.g., cracked flanges, broken wooden or plastic parts) that may have occurred during transportation.

Inspect the cable’s outer sheath for cuts, abrasions, or punctures, which could compromise its performance.

Verify the length and specifications match the order confirmation (e.g., 3-core 2.5mm² cable on a 100m reel).

Ensure the labeling is intact and legible, as this contains important information for installation and compliance.
