Raw Materials: The primary materials used in the production of direct bury wires include copper or aluminum conductors and insulation materials such as thermoplastic (PVC) or thermosetting (XLPE) compounds. The choice of materials is crucial as they must resist moisture, chemicals, and temperature fluctuations.

Material Testing: Before processing, raw materials undergo quality testing to ensure they meet specified standards. This includes verifying the conductivity of metals and the durability of insulation materials.

2. Forming

Wire Drawing: The manufacturing process begins with wire drawing, where copper or aluminum rods are drawn through a series of dies to achieve the desired gauge. This process enhances the wire’s strength and conductivity.

Stranding: For multi-conductor wires, individual strands are twisted together. This stranding process increases flexibility and reduces the risk of breakage during installation.

3. Assembly

Insulation Application: The next stage involves applying insulation to the conductor. This is typically done using extrusion techniques where the insulation material is heated and then applied around the wire. This step is critical as it ensures that the wire is protected from moisture and other environmental factors.

Shielding: In some cases, additional layers such as shielding may be applied to enhance protection against electromagnetic interference (EMI) and physical damage.

4. Finishing

Jacketing: The final step in the manufacturing process is the application of an outer jacket. This layer provides additional protection against environmental elements such as soil, moisture, and chemicals. It is essential that the jacket material is durable and compliant with local regulations.

Cutting and Spooling: Once the wires are fully assembled, they are cut to length and spooled for packaging. Proper handling during this stage is necessary to prevent damage.

Quality Assurance

Quality assurance is a cornerstone of manufacturing direct bury electrical wire. It ensures that the final product meets safety standards and performs reliably under various conditions.
