Do you want to customize PVC wire?
PVC wire is a term that is often used in discussions about electrical wires. People who have little understanding of electric wires may know that in terms of material and performance, electrical wires include various types such as PVC wires, flame-retardant wires, and anti-corrosion wires. And PVC wire is something we usually encounter, so today, let’s learn what PVC wire is, whether it is good, and its buy skills.
What is PVC Wire?
PVC wire means that the outer material wrapping the core material is made of polyvinyl chloride. In a sense, it is also an insulated wire. So, how did the PVC wires develop?
Due to PVC materials’ superior physical properties and good flame retardancy, it has gradually been used more and more widely. It has been used as a wire insulator since the 1930s and 1940s. It is precise because of the continuous improvement of the production capacity of PVC materials and industrial additives that the cable industry has made a qualitative leap.
In general, the development of PVC materials has mainly experienced the transformation and development from ordinary to flame-retardant, and then to non-lead, technical, etc., and has also played a great role in the cable and wire industry. This is also why we can often see various PVC wires now.
What is PVC Wire Insulation?
PVC is a thermoplastic material that softens with heat, a factor that eases wire production and allows manufacturers to extrude the PVC wire insulation. You can use PVC electrical cable and hook-up wire for internal appliances and electrical equipment wire.
PVC Wire Construction
PVC wire conductors use copper wire or tinned copper wire. The American wire gauge (AWG) sizes vary from 30 to 4/0. Conductors consist of multiple strands of thin copper wire. An extruded PVC insulation covers the conductor, and the insulation may be relatively stiff or flexible depending on individual wire specifications.
What Are the Advantages of PVC Wire?
Many decoration masters will tell us that electrical safety is the priority in a family. The premise of ensuring the safety of electricity is that the quality of the wires must be qualified. So, what are the advantages of PVC insulated wire?
In terms of performance, PVC wires have many characteristics, such as good insulation and flame retardancy, which can prevent the occurrence of electric leakage due to short circuits and faults; good corrosion resistance and strong resistance to harsh natural environments ability; durable, on the premise of protecting the electrical wire, keeping the wire away from external threats, thereby improving the service life of the wire; at the same time, the maintenance cost of the PVC wire is relatively low.
In summary, PVC cables and wires have many advantages, but the basic condition to ensure these characteristics is that the PVC wires are of high quality.
PVC Wire Applications
PVC wire applications include the internal wiring of electronic equipment, power supply, lighting, telecommunications, and electrical appliances. Other PVC cable applications include power, industrial, and automotive cables.
Do you now understand what PVC wires are? And how do you identify PVC wire? You may also have some other problems when you buy PVC cables? There we list the most prevalent issues which our buyers always ask.
How Do I Choose the Right PVC Wire?
Wires must be selected carefully as a home improvement material that supports our long-term electricity use. We are necessary to understand the purchase precautions. We prepared 3 tips on how to choose a suitable PVC wire.
First, look at the PVC material.
Usually, to save some PVC material costs, some bad wire manufacturers either choose inferior PVC materials or cut corners. Suppose it takes some professional knowledge to distinguish the quality of PVC material. In that case, we can analyze the quality of the insulation layer of the wire from the aspects of the surface thickness, uniformity, and flaws of the insulation layer of the wire.
Second, look at the length and wire diameter.
The length and wire diameter of the national standard wire are stipulated. For example, the length and wire diameter of the BV2.5 square wire should be 100 meters and 1.78 mm, respectively. If the length error is greater than 1 meter when purchasing, it means that the quality of the wire is not good.
Third, look at the quality of copper.
Most wires are made of copper. If the copper is high quality, it will look reddish purple instead of yellow; high-quality copper is relatively soft.
What is the Difference Between PVC and XLPE cable?
The main difference is that XLPE can be used for high and low tension applications. Its structure provides great resistance to abrasion, stress, and other wear and tear, and PVC insulation cannot withstand as much pressure, making it only suitable for low tension applications.
