Hong Kong-made tensile corrosion-resistant multi-core cable 12*1.5, various specifications of festoon flexible cable 7*2.5

The 12*1.5 multi-core tensile corrosion-resistant cable for port machinery and the 7*2.5 drag-chain flexible cable in various specifications are high-performance cable products specifically developed and manufactured by Shanghai Okesen Wire & Cable Co., Ltd. to meet the demands of port machinery equipment. This article will provide an in-depth introduction to the advantages and characteristics of these two products from aspects such as application scope, installation methods, precautions, material composition, and manufacturing processes, helping users gain a comprehensive understanding and choose suitable cable solutions.

1. Wide Application Range, Adaptable to Complex Working Environments

The 12*1.5 multi-core tensile corrosion-resistant cable for port machinery is primarily used in large port machinery equipment such as port cranes and container bridge cranes. It can withstand harsh port environmental conditions, including high mechanical tension, salt spray corrosion, high humidity, and temperature variations. The 7*2.5 drag-chain flexible cable in various specifications, due to its high flexibility and wear resistance, is suitable for cable wiring in mobile equipment such as drag-chain carts, electric forklifts, and warehouse handling machinery, particularly in scenarios involving frequent bending and movement. Beyond port machinery, both types of cables are also suitable for industrial production lines, overhead conveying equipment, and other electrical devices requiring high tensile strength, corrosion resistance, and multi-core wiring, meeting various operational requirements.

2. Standardized Installation Procedures to Ensure Safety

• Before installation, inspect the cable’s exterior to ensure there is no obvious damage, cracks, or moisture.

• Choose appropriate laying methods, such as direct burial, conduit, or tray installation, to ensure mechanical protection and avoid external compression.

• Maintain a reasonable bending radius for port machinery multi-core cables to prevent internal conductor breakage or insulation damage due to bending.

• Select installation accessories that comply with power cable standards for drag-chain flexible cables to ensure secure connections and free movement.

• Use matching waterproof and anti-corrosion materials at connection points to prevent moisture ingress and extend service life.

Rigorous installation procedures not only safeguard the cable’s electrical performance but also reduce long-term maintenance costs and extend equipment operational cycles.

3. Installation and Usage Precautions

1. Avoid direct contact between the cable and sharp objects to prevent insulation cuts.

2. Regularly inspect the cable surface for wear or cracks and take protective measures promptly.

3. In high salt spray environments, consider anti-corrosion surface coatings if necessary to protect the cable from corrosion.

4. Do not overload the cable; distribute the load according to the rated current.

5. Avoid prolonged tension or twisting of the cable, especially for flexible drag-chain cables, to maintain elasticity.

6. In low-temperature environments, note that cable flexibility decreases; handle with extra care during operation.

Proper usage and maintenance are crucial for ensuring long-term stable cable operation.

4. High-Quality Materials Ensure Durability and Safety

The 12*1.5 multi-core tensile corrosion-resistant cable for port machinery uses high-quality copper core conductors to ensure efficient power transmission, with high conductor density reducing resistance and heat generation. The insulation employs cross-linked polyethylene (XLPE) material with excellent high-temperature and flame-retardant properties, providing strong electrical insulation. The outer sheath is made of high-molecular weather-resistant material, specially treated with anti-UV and salt spray corrosion components to enhance outdoor durability.

The 7*2.5 drag-chain flexible cable uses a fine-stranded copper wire structure, significantly improving flexibility and fatigue resistance. The insulation layer also employs eco-friendly flame-retardant materials to ensure safety during mechanical bending. Additionally, the outer sheath may use wear-resistant PVC or polyurethane materials depending on the application environment, enhancing overall service life.

Material selection reflects a high level of responsibility for customer safety and product stability.

5. Advanced Manufacturing Processes Ensure Product Quality

Shanghai Okesen possesses independent R&D capabilities and a strict quality management system, overseeing the entire cable production process from copper wire selection, insulation extrusion, core combination, sheath extrusion, to final product testing. Automated control equipment ensures uniform wire diameter and insulation thickness, minimizing human error.

Corrosion resistance treatments and flexible designs undergo repeated testing and validation to meet the complex electrical demands of port and industrial environments. Each cable undergoes high-voltage and tensile tests before leaving the factory to ensure compliance with national and industry standards.

Attention to process details demonstrates technical strength and is a key factor in ensuring product performance and customer satisfaction.

6. Summary and Recommendations

The 12*1.5 multi-core tensile corrosion-resistant cable for port machinery and the 7*2.5 drag-chain flexible cable are specifically designed for port machinery and high-intensity industrial environments, offering excellent tensile strength, corrosion resistance, and flexibility. When selecting cables, it is important to not only consider specifications and price but also focus on manufacturing processes and materials, as these directly impact equipment stability and safety.
