10mm² Cable: In medium-sized trucks, in addition to the starter motor lines and power supply for refrigeration units of refrigerated trucks, it can also be used for power supply of equipment such as on-board air conditioners and hydraulic lifting systems. For urban buses, it can be used as the main power supply line for door control motors, wiper motors, etc., which can withstand the continuous current generated by the long-term operation of the vehicle and ensure the normal operation of the equipment.

16mm² Cable: In heavy trucks, in addition to battery pack series lines, it can also be used for power supply of high-power equipment such as on-board cranes and lifting motors of dump trucks. In engineering vehicles, such as excavators and loaders, it can be used as the engine start line and the control line of the main hydraulic system, maintaining stable power transmission under bumpy road conditions, ensuring the smooth start of the engine and the normal operation of the equipment.

High-temperature Scenarios: For wire harnesses near the exhaust pipe in the engine compartment, in addition to the 90℃ temperature resistance, the cable has also undergone a thermal cycle test. After 1000 cycles in the temperature cycle of -40℃ to 90℃, the insulation layer has no cracking or aging, still maintaining good insulation performance.

Oil-contaminated Environments: For cables near the gearbox, in addition to the oil-resistant sheath, special sealing treatment is adopted, and an oil-resistant sealing ring is added at the interface connected to the gearbox to further prevent oil penetration. During long-term use, even if the surface of the sheath is contaminated with oil, it will not affect its insulation performance and mechanical properties.

Low-temperature Areas: In a severe cold environment of -40℃, the cable not only maintains flexibility but also has undergone a low-temperature impact test. After being placed at -40℃ for 24 hours, a bending test is carried out with no cracks. This ensures that when the vehicle starts in extremely cold weather in winter, the cable will not break due to embrittlement, ensuring the normal use of the vehicle.

The temperature-resistant PVC material of the insulation layer is made by mixing polyvinyl chloride resin, plasticizers, stabilizers and other components in precise proportions. Among them, the plasticizer uses environmentally friendly phthalates, which have good cold resistance and heat resistance, ensuring that the insulation layer maintains flexibility in a wide temperature range. The stabilizer can effectively prevent PVC from decomposing due to heat during processing and use, extending the service life of the insulation layer.

The flame-retardant PVC material of the sheath layer, in addition to adding flame retardants and oil-resistant additives, also adds ultraviolet absorbers, which can resist ultraviolet radiation in sunlight and prevent the sheath from aging. In terms of color, the sheath layer usually adopts black, which is not only resistant to dirt but also can absorb heat, reducing the impact of temperature changes on the sheath performance. At the same time, the black sheath is compatible with the environment in the car engine compartment and is not easy to get dirty.

1.5mm² and 2.5mm² Cables: Usually packaged in reels, with plastic reels with a diameter of 300mm, each reel can hold 100 meters of cable.

The length of each reel of cable is usually 50 meters or 100 meters. The wooden reels are made of high-quality pine wood, which has been dried with a moisture content of ≤15% to prevent the reels from deforming during use. The diameter of the steel shaft of the reel is 50mm, which can bear a large weight.

Before the cable is coiled, the surface is wrapped with a layer of plastic film with a thickness of 0.05mm, which has good moisture-proof and dust-proof performance. For export products, an additional layer of kraft paper is wrapped outside the plastic film to enhance the strength and moisture-proof performance of the packaging.

The outside of the reel is fixed with steel strips with a width of 16mm and a thickness of 0.5mm. Each reel of cable is fixed with at least 4 steel strips to ensure that the cable does not loosen during transportation. The two ends of the reel are covered with plastic covers to protect the ends of the cable from damage.

Short-distance Transportation (distance ≤500km): Using box-type trucks for transportation, the interior of the truck compartment is clean, dry, and free of sharp objects. The cable reels are placed horizontally in the truck compartment, and wooden boards are used between the reels to prevent mutual collision. A layer of rubber pad is laid at the bottom of the compartment to reduce vibration during transportation.

Long-distance Transportation (distance ＞500km): Railway transportation or long-distance road freight can be

Export Transportation: Sea or air transportation is used. For sea transportation, cable reels are loaded into containers, and moisture-proof treatment is done inside the containers with desiccants placed. For air transportation, due to strict restrictions on weight and volume in air transport, small-sized reels are usually used for packaging to reduce transportation costs.

During loading and unloading, forklifts or cranes should be used, and manual dragging of reels is strictly prohibited. Loading and unloading should be done gently to avoid collision and falling of reels. The length of the forklift tines should be greater than the diameter of the reels to ensure the reels remain stable during loading and unloading.

During transportation, cables should be protected from direct sunlight, rain, and snow to prevent moisture and aging. When transporting in open vehicles, they should be covered with waterproof cloth.
