Manufacturing

We adhere to a lean production process that ensures consistent and high-quality products at a fraction of the cost and production time.

Cable Production Process

Wire Drawing

Electrical copper rods are drawn into their required size using various drawing machines, which are then annealed to be more manageable.

Stranding

Several wires with the same diameter are placed on a wire stranding machine, twisting the wires together to form the cable’s core.

Insulation Extrusion

The preferred insulation material is extruded onto the newly stranded wires, giving it much-needed protection and flexibility.

Stream Cross-Linking

To improve its resistance to temperature and stress, the wires are subjected to a stream cross-linking process.

Cable Formation

Several insulated wires are twisted together, forming the core of the cable. We use a dedicated cable-forming machine in this process.

Sheath Extrusion

Another layer of protection is added on the cable to protect the insulated layer, called a sheath.

Printing

The company’s name, cable model, voltage level, production date, and other details are printed onto the surface.

Inspection

Expert inspectors audit the completed cables, checking for any inconsistencies and testing their performance.

Packaging

Once the cables pass the testing, we pack them using high-grade materials and place them in a warehouse, ready for shipment.

Materials

Only the Best Materials

Knowing that the overall quality of a product depends on the parts used to build it, Panyu Cable Group uses only the finest raw materials to create your custom cable products. From working with well-vetted material suppliers to careful inspection once the materials arrive, we leave no stone unturned to ensure the raw materials meet our high standards.

Testing

To ensure the quality, consistency, and performance of our cable products, we subject them to a series of tests in accordance to global benchmarks.
