How It’s Made
Wire and cable are typically made through a process that involves several steps:
Drawing
The first step is to draw the metal (usually copper or aluminum) into a wire of the desired diameter. This is done by pulling the metal through a series of dies, which gradually reduce the diameter of the wire.
Stranding
In this step, multiple wires are twisted together to form a strand. The number of wires and the direction of the twist depend on the specific application of the cable.
Insulating
The next step is to add an insulating material around the wire or strand to protect it and to prevent electrical interference. Common insulating materials include PVC, rubber, and Teflon.
Cabling
In this step, multiple insulated wires or strands are twisted together to form a cable. The number of wires and the direction of the twist depend on the specific application of the cable.
Jacketing
The final step is to add an outer jacket to the cable for protection and to provide a finished look. The jacket can be made of materials such as PVC or nylon.
The exact process and materials used to make wire and cable can vary depending on the specific application and the manufacturer. It’s important to follow industry standards and regulations to ensure the safety and reliability of the product.
