VVD Series High Current Cable Product Introduction

The VVD series high current cables, as innovative products for high current transmission and distribution applications, are flexible cables designed and manufactured by combining traditional cable manufacturing processes with new materials, using high-purity copper wires as conductors. The product structure primarily consists of copper conductors, wrapping layers, insulation layers, armor layers, and sheath layers, utilizing materials with corresponding functions based on different application scenarios. These flexible cables replace multi-core cables, traditional busbars, and busway systems in specialized fields.

Model and Specification Range

Advantages of High Current Cable Products:

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

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

1.3 Flexibility: Can be folded and bent according to installation requirements with a large bending angle, easily fitting into narrow, irregular, and various other spaces.

1.4 Vibration Resistance: Self-elastic, capable of absorbing vibrations during equipment operation, thus preventing loosening, metal fatigue, or even breakage caused by long-term vibration after traditional busbar connections.

1.5mm Position Compensation: When there is a 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, High Maintenance" to "Cost Reduction and Efficiency Improvement"

2.1 Material and Comprehensive Cost: High current cables can be directly connected to distribution cabinets 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 on buildings, reducing the need for brackets or bridge structures, improving construction efficiency, and lowering the comprehensive cost by over 10% compared to traditional solutions.

2.2 Operation and Maintenance Costs: Free from multi-junction hazards, reliable insulation and protection, virtually maintenance-free, significantly reduces long-term operation and maintenance costs and fault losses, energy-saving and consumption reduction, low line loss, 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 length can reach hundreds of meters without intermediate joints, eliminating the need for connectors/bends, reducing failure points, and suitable for long-distance wiring (such as factories, ultra-fast charging stations, data centers, etc.).

3.2 Minimal Installation: Can be rolled for transport, and can be cut, drilled, and bolted on-site, without the need for copper nuts and complex splicing. Can be completed quickly by 1-2 people, significantly reducing construction time.

3.3 High Adaptability: Can flexibly bend into U-shaped and L-shaped paths, easily navigate through narrow cabinets and around pipes. No need for factory customization during改造 and expansion, with high reuse rate.
