Dimensional Inspection:
Measure the dimensions of the copper material to ensure it meets the required specifications

Electrical Conductivity Testing:
Measure the electrical conductivity of the copper material to verify its conductivity properties.

Visual Inspection:
Conduct a visual inspection of the copper material to check for any signs of damage, defects, or irregularities

Sizing and Control:
The diameter and thickness of the insulation layer are controlled by the design of the extrusion die and the processing parameters, such as temperature, pressure, and extrusion speed. Monitoring and control systems ensure that the insulation layer meets the specified dimensions and quality standards.

Preparation:
The insulated wires are typically prepared by polymeric insulation material around the conductor, as described earlier.

Heating Stage:
The insulated wires are subjected to heat to initiate the curing or cross-linking process of the insulation material.
The temperature and duration of heating are carefully controlled to ensure proper curing or cross-linking of the insulation material without causing damage to the wires.

Preparation:
Set up the coiling equipment, including spooling machines or manual winding tools, in a clean and organized workspace.

Wire Feeding:
Begin the coiling process by feeding the manufactured submersible wire onto the coiling equipment.

Winding:
Use appropriate winding techniques to ensure that the wire is evenly distributed and tightly wound onto the spools or reels without gaps or overlaps.
Monitor the coiling process closely to detect any irregularities or defects in the wire or spooling equipment.

Product Identification and Labeling:
Label each package with essential information, including product name, specifications, quantity, batch number, and customer details.
Attach shipping labels, barcodes, or tracking numbers to facilitate inventory management and shipment tracking.
