XLPE Flexible Cable

0.00

The Flexible XLPE Insulated Cable is a high-performance cable that uses cross-linked polyethylene (XLPE) as the insulation material, combined with fine-stranded copper conductors and PVC or rubber sheaths. It offers excellent thermal resistance, electrical properties, mechanical strength, and flexibility. Rated up to 450/750V, it is widely used for power transmission, control, and equipment connections in demanding industrial environments, such as automation systems, machine tools, ships, power stations, and mobile electrical installations.

FAQ

1. What is an XLPE Flexible Cable?
A cable with cross-linked polyethylene (XLPE) insulation designed for flexibility and high thermal resistance.

2. Where is it commonly used?
Used in industrial machinery, control systems, power distribution, and environments requiring flexible cable installation.

3. What are its main construction features?
Copper conductors, XLPE insulation, and an outer sheath (PVC or other protective material) for mechanical and environmental protection.

4. What are the benefits of XLPE flexible cables?
High temperature resistance, excellent electrical performance, flexibility, and durability in harsh environments.

5. How to select the right XLPE flexible cable?
Consider voltage rating, current capacity, environmental conditions, and flexibility requirements.

6.Can cables be used outdoors or buried underground?
Yes, but outdoor or direct-burial cables require UV-resistant, water-resistant, or armored designs to withstand environmental conditions.
