Do you want to produce PVC cables? If yes, then this article is worth a look
A cable consists of two or more wires that are twisted or braided together. Wires and cables are encapsulated in a non-conductive plastic material, usually PVC, XLPE, or other materials. Today, we will take you to know about PVC cables, including applications, advantages, and how to produce them with our Electrical Wire Cable Making Machine.
1. Application of PVC Cables:
PVC is generally used for the insulation and sheathing of cables, and PVC cables are used to power countless appliances and electrical equipment. From refrigerators, washing machines, air conditioners, and televisions to increasingly popular consumer electronics such as personal computers, laptops, smartphones, tablets, and other IT equipment, PVC cables are widely used in residential, commercial, and industrial applications, even for applications such as The same applies to heat-sensitive environments such as kitchens and mining operations, which are an integral part of our daily lives. Our Electrical Wire Cable Making Machine is designed to produce such cables.
2. Advantages of PVC Cables:
2.1 Strong Durability
PVC cables are very durable. The availability of PVC cable and its overall life compared with other cables have a certain uniqueness. In most cases, PVC cables are resistant to corrosion, wear, chemical corrosion, and water. For some industries, additives such as plasticizers are added to PVC sheathing to make it more durable and resistant to toxic chemicals. In addition, they are rust-resistant and
shock-absorbing, which further improves durability. Generally speaking, PVC cables can last up to 70 years under normal service conditions.
2.2 Flame Retardant
PVC cables are flame retardant, which can reduce or suppress combustion and prevent flames from spreading in the event of a fire. This is because the PVC sheath is self-extinguishing. In case of a fire accident, the cable will stop when the fire source is removed. combustion. With the addition of additives in the sheath, PVC cables can withstand temperatures ranging from -40 to 105°C. Whether used indoors or outdoors, all cables must maintain high safety standards. PVC provides insulation, strength, and protection over a wide range of operating temperatures. This is critical for internal wires, cables, and optical fibers used at very low temperatures (buried underground or under the sea) and very high temperatures (near powerful engines, such as in automotive applications).
2.3 Recyclable
Another advantage of PVC cables is that they can be easily recycled. Nearly 100,000 tons of scrap cables are recycled every year. The recycling process for PVC cables involves separating the PVC jacket from other valuable metals, usually copper or aluminum, which are easily recycled. The process focuses on separating PVC compounds from other materials (other plastics, rubber, metals, textiles, etc.) by selectively dissolving and filtering them.

In addition, PVC cables are lead-free, making them more environmentally friendly than other cables and wires, as leaded cables are environmentally harmful during use or disposal, and are more cumbersome to recycle.
2.4 Easy to install and handle
PVC is known for being flexible and easy to shape. PVC can be used, joined, and welded into any shape, which ensures that PVC cables are available in various sizes and styles, and highly customizable for any complex needs. PVC cables are lightweight and easy to handle.
3. How to produce PVC cable?
PVC Cables Manufacturing Process
The whole process includes the following machines.
3.1 Rod Breakdown Machine or other types Wire Drawing Machine with Annealing :
8mm copper rods are drawn into different specifications of wires and annealed, Annealing is the process of slowly cooling a metal to relieve internal stress and toughen the metal. In the manufacture of wire and cable, the wire is softened by annealing. Great pressure is applied to the metal rod to form finer wires. The purpose of heating annealing is to avoid cable oxidation.
3.2. Wire Stranding or Twisting Machine:
Stranding multiple wires into one group for greater flexibility and electrical performance.
3.3.Cable Extrusion Machine
Basically, extrusion is a method in which materials undergo a plastic deformation process by applying a force and letting material flow through a die or orifice. In this step, Copper conductors (wires) of a specified size are fed into an extruder where PVC is coated around the wire to a specified thickness. Next, the coating with PVC passes through cooling water tanks, and the cable is sent to the take-up machine, where it is coiled to the specified length.
3.4 Cable Coiling
Finished products such as insulated conductors (flexible or rigid) and some small cables are rolled into bundled coils, wrapped in plastic or shrink foil, and sometimes packed in cardboard boxes and placed on pallets.
These operations can be done manually, semi-automatically, or automatically using winders. The automatic coiling machine is usually linked with the extrusion line, synchronous insulation/sheath extrusion + automatic coiling + automatic labeling + film + carton packaging.
