Product Advantages

Special Shielded Cables offer numerous benefits that make them ideal for crane applications:

1. High Flexibility

• Designed for continuous bending and movement in crane systems.

• Supports dynamic operations without compromising conductor integrity.

2. Mechanical Strength

• Reinforced outer sheath resists abrasion, tearing, and crushing.

• Stranded copper conductors provide durability under high mechanical loads.

3. Electromagnetic Shielding

• Integrated foil and braided shielding minimizes interference.

• Ensures reliable data transmission and operational safety.

4. Environmental Resistance

• PVC or PUR outer sheaths protect against oil, chemicals, moisture, and UV exposure.

• Suitable for indoor and outdoor crane applications.

5. Long Service Life

• Engineered for millions of bending cycles.

• Maintains performance under heavy-duty conditions.

Quality Control

Ensuring consistent quality is vital for crane cable performance. Our quality control process includes:

Incoming Material Inspection

• Raw materials are tested for conductivity, tensile strength, and flexibility.

• Sheath materials undergo chemical and mechanical resistance tests.

Manufacturing Process Control

• Automated extrusion ensures uniform insulation thickness.

• Shielding is applied consistently to guarantee EMI protection.

• Stranding and cabling are monitored for uniformity and integrity.

Final Testing

• Electrical tests: Continuity, insulation resistance, and high-voltage tests.

• Mechanical tests: Bend, tensile, and torsion testing.

• Environmental tests: Temperature, moisture, and chemical resistance.

Continuous Improvement

• Feedback from field applications informs design refinements.

• ISO 9001 certified processes ensure systematic quality management.

Certification Standards

Special Shielded Cables meet or exceed international standards for safety, performance, and environmental compliance:

Components List

Understanding the components of Special Shielded Cables is essential for maintenance, replacement, and system integration.
