ZR-VVD Series High Current Cable Product Introduction

The Z(A, B, C)-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 technology with new materials, using high-purity copper wires as conductors. The product structure mainly consists of copper conductors, wrapping layers, insulation layers, armor layers, and sheath layers, utilizing materials with corresponding functions based on different usage scenarios. These flexible cables can replace multi-strand 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, with the maximum reaching 3200A per strand, one strand can replace multiple cables in parallel; no eddy currents, large heat dissipation surface, which can reduce joints, lower temperature rise, and provide more stable long-term operation.

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, offering resistance to moisture, 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 wide bending angle, easily fitting into narrow and irregular spaces.

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

1.5mm 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 High Maintenance" to "Cost Reduction and Efficiency Enhancement"

2.1 Materials and Overall Cost: High-current cables can be directly connected to switchboards, eliminating the need for accessories like copper sockets within the switchboard, significantly reducing the cost of copper auxiliary materials. Under the same load current, they weigh approximately 40% less than traditional busbars, thus lowering the structural load-bearing pressure, reducing the amount of support brackets or bridge structures needed, improving construction efficiency, and overall costs are reduced by over 10% compared to traditional solutions.

2.2 Operation and Maintenance Costs: Free from multi-joint hazards, reliable insulation and protection, virtually maintenance-free, significantly reducing 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: Continuous lengths up to hundreds of meters without intermediate joints, eliminating the need for connectors/ells, reducing failure points, and suitable for long-distance wiring applications (such as factories, ultra-fast charging stations, and data centers).

3.2 Minimal Installation: Rollable for transportation, on-site cutting, drilling, and bolt fastening required; no need for copper terminals or complex connections. Can be completed quickly by 1-2 people, significantly reducing the construction timeline.

3.3 High Adaptability: Can be flexibly bent into U-shaped or L-shaped paths, easily passing through narrow cabinets and around pipes. No need for factory customization during改造 or expansion, with high reusability.
