WDZ-YJYD Series High Current Cable Product Introduction

The WDZ-YJYD series high current cables, as innovative products for large current transmission and distribution applications, are flexible cables made with high-purity copper wires as conductors. They combine traditional cable manufacturing techniques with new materials. 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 can replace multi-strand cables, traditional busbars, and busway in specialized 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, up to 3200A per strand, allowing for the replacement of multiple cables in parallel; no eddy currents, large heat dissipation surface, reducing the need for joints, lower temperature rise, and 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. It is resistant to moisture, corrosion, and high temperatures, suitable for harsh environments such as outdoor, energy storage, and chemical industries.

1.3 Flexibility: Can be folded or 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, preventing loosening, metal fatigue, or even breakage caused by long-term vibration after traditional busbar connections.

1.5 Position Compensation: When the two connected components have slight relative displacement due to temperature changes (expansion and contraction) or assembly deviation, the high current cable can offset 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 Enhancement"

2.1 Material and Comprehensive Cost: High current cables can be directly connected to distribution cabinets without requiring accessories like copper terminals inside, significantly reducing the cost of copper auxiliary materials. At the same current carrying capacity, they are about 40% lighter than traditional busbars, alleviating the load-bearing pressure of buildings, reducing the need for supports or bridge structures, improving construction efficiency, and lowering the comprehensive cost by more than 10% compared to traditional solutions.

2.2 Operation and Maintenance Costs: Free from multi-joint hazards, reliable insulation and protection, minimal maintenance required, significantly reduces long-term operation and maintenance costs and fault losses, energy-saving and consumption reduction, low line loss, high power usage efficiency, can save considerable electricity costs over the long term, aligns with the "dual carbon" requirements.

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

3.1 Long-distance Integrated Laying: Single length up to several hundred 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: Rollable for transport, simply cut, drill, and bolt on-site; no need for copper ferrules or complex terminations. Can be completed by 1-2 people quickly, significantly reducing construction time.

3.3 High Adaptability: Can be flexibly bent into U-shaped, L-shaped paths, easily navigating through narrow cabinets and around pipes. No need to return to the factory for customization during modification or expansion, with high reuse rate.
