PVC insulated cable includes single-core PVC insulated cable and multi-core PVC insulated cable. In the electrical industry, electric engineers focus on it and are the main choice for their electrical projects. Pvc insulated copper wire not only has its’ advantages but also its disadvantages. We will discuss this topic today, but first of all, we should know what is use of it. So today’s article mainly includes three topics.
Please visit our website for more information on this topic.
- What is the use of PVC insulated cable
- Advantages of PVC insulated cable
- Disadvantages of PVC insulated cable
Firstly, we will introduce the usage of PVC insulated wire.
What is the use of PVC insulated cable
According to the features of PVC material, there are mainly five kinds of PVC insulated industrial cables.
High heat resistance, flame retardant PVC cable wire
Applicable to supporting cables for color TV sets with a maximum conductor temperature of 105℃ and below. Such as installation wires, cords, and power wires. For marine cables, 3.6/6KV power cables, 450/750V, and below heat-resistant wires and cables.
Heat resistance 90℃ flame retardant PVC wires and cables
Suitable for additional voltage U. /U≤1.8/3KV and below marine cables, control cables, subway, and tunnel cables.
Extra voltage 1KV and below aerial PVC power cable
Suitable for transmitting and distributing electric energy, and is often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas.
Heat-resistant flame retardant 450/750 PVC insulated non sheathed cable
Suitable for house wiring cable, house construction, household electrical appliances, instrumentation, etc.
Heat-resistant 70℃ flame-retardant PVC insulated multi strand control cable
Suitable for rated voltage 300/500V and below control system, signal transmission, monitor loop, and protecting wire. And also suitable for other indoor occasions like metallurgy, electric power, construction, and other industries.

Secondly, we will list the advantages of PVC insulated and sheathed cables.
Advantages of PVC insulated cable
The full name of PVC is Polyvinyl chloride, this insulation material adds stabilizers, plasticizers, flame retardants, lubricants, etc. These elements can be well used according to different requirements of electric wire. After decades of producing and using, PVC wire manufacturing and processing technology are very mature. It also presents many benefits in a wide range of applications.
- Cost lower. Compare with other insulating cables, PVC insulated flexible cable has the advantage of cheaper cost. This PVC insulated flexible copper wire not only costs lower but also has the features of brightness surface, easy to typing words, processing efficiency, flexibility, and controllable mechanical and physical properties.
- Ease of operation. Since PVC insulated multi-strand wire has the strong ability of flexibility, it is easy to install and maintain. If there is something wrong with the cable used, since the cost is lower, you can replace it easily.
- Has very good flame-retardant properties. Since the PVC insulation material has the characteristics of self-extinguishing from fire, the flame retardant of PVC insulated copper wire is also strong. Can ensure the safety of use.
- Wide range of applications. PVC insulated sheathed cables are widely used for many situations. No matter the electrical rated voltage of 300/500V, or appliances rated voltage of 450/750, PVC copper wire is the first choice. It can also carry a rated voltage of 0.6/1KV power electrics. PVC insulated industrial cables are not only suitable for control systems, fire alarm systems, and signal transmission systems, but also suitable for house wiring appliances, and overhead power engineering.
- Environmental protection is good. Since PVC insulation and sheath material is a kind of green environmental material, PVC electric cables are also friendly to the environment. It will not produce harmful substances to people's life and health.
- As a reliable PVC cable supplier, Henan Shenbei Industrial Co. Ltd. supplies enough length, enough conductor, and the highest full national standard single-core and multi-core PVC wire.
Finally, there are also some disadvantages of PVC insulated flexible copper wire we need to introduce.
Disadvantage of PVC insulated cable
- Poor performance of acid and alkali resistance, heat-resistant oil, and organic solvent resistance, these points make PVC insulated flexible copper wire easily damaged and cracked in the specific environment.
- Weather resistance is not strong. A normal PVC insulated sheathed cable working temperature is -10℃-70℃. For cold temperatures below -20℃ and hot temperatures exceeding 90℃, special PVC material is needed. This will add to the cost. This disadvantage point also limits outdoor installation.
- It will cause smoking when burning, this may make harmful to our environment. If you want to solve this problem, you can customize LSZH PVC wire, but this kind of material will also add to the cost.
Now, do you have an idea of the advantages and disadvantages of PVC insulated cable? Do you want to buy high-quality PVC copper wire a unique discount? Welcome your inquiry.

Say I've calculated the minimum wire gauge necessary to give me an acceptable voltage drop over my length of cable run at the voltage and current my application will use.
Are there any disadvantages to using thicker cable, aside from cost? Is the answer different for AC vs DC? For power vs signal transmission?
