YJVD Series High Current Cable Product Introduction

The YJVD series high-current cables, as innovative products for high-current transmission and distribution, are flexible cables made by combining traditional cable manufacturing processes with new materials, using high-purity copper wire as the conductor. The product structure is primarily composed of copper conductors, wrapping layers, insulation layers, armor layers, and sheath layers, with materials selected based on the specific application requirements. These flexible cables can replace multi-strand cables, traditional busbars, and busway in special fields.

Model and Specification Range

Advantages of High Current Cable Products:

Performance and Reliability: From "Tolerance" to "Compatibility"1.1 Higher current density under the same cross-section, with the highest reaching 3200A per strand; one strand can replace multiple cables in parallel; no eddy current, large heat dissipation area, can reduce joints, low temperature rise, and more stable operation over a long period.

1.2 Protection and Insulation Advantages: Combines the high current-carrying capacity of busbars with the continuous waterproof and dustproof grade of power cables up to IP68. It is resistant to moisture, corrosion, and high temperatures, suitable for harsh environments such as outdoor, energy storage, and chemical industries.

1.3 Bendability: Can be folded or bent to accommodate installation requirements with a large bending angle, easily fitting into narrow and irregular spaces.

1.4 Vibration Resistance: Features inherent elasticity to absorb vibrations during equipment operation, preventing loosening, metal fatigue, or even breakage caused by long-term vibration after traditional busbar connections.

1.5mm Position Compensation: In the event of slight relative displacement between the two connected components due to temperature changes (expansion and contraction) or assembly tolerances, the high current cable can compensate for the displacement through deformation, ensuring the stability of the conductive connection.

2. Cost and Energy Consumption: From "High Investment and Maintenance" to "Cost Reduction and Efficiency Enhancement"

2.1 Materials and Comprehensive Costs: Large current cables can be directly connected to the distribution cabinet without the need for accessories like copper sockets inside, significantly reducing the cost of copper auxiliary materials. At the same load current, they are approximately 40% lighter than traditional busbars, alleviating the load-bearing pressure of buildings, reducing the amount of brackets or bridges needed, improving construction efficiency, and lowering the comprehensive cost by over 10% compared to traditional solutions.

2.2 Operation and Maintenance Costs: No隐患 of multiple joints, reliable insulation and protection, essentially maintenance-free, significantly reduces long-term operation and maintenance costs and fault losses, energy-saving and consumption reduction, low line loss, and high power usage efficiency. Long-term operation can save considerable electricity costs, aligning with the "dual carbon" requirements.

3. Construction and Flexibility: From "Complex Customization" to "Ready-to-Use"

3.1 Long-distance Integrated Laying: A single cable can reach several hundred meters without any intermediate joints, eliminating the need for connectors or elbows, reducing failure points, and suitable for long-distance wiring (such as factories, ultra-fast charging stations, and data centers, etc.).

3.2 Minimal Installation: Can be rolled for transportation, on-site cutting, drilling, and bolted together - no need for copper connectors or complex wiring. Can be quickly completed by 1-2 people, significantly shortening the construction timeline.

3.3 High Adaptability: Can flexibly bend into U-shape or L-shape, easily navigate through narrow cabinets and around pipes. No need to return to the factory for customization during改造 and expansion, with high reusability.
