What is the difference between PVC and rubber cable?

While both rubber coated cables and PVC cables are commonly used in electrical applications, they differ in structure composition, application areas, and performance qualities, as detailed below:

Structure:

Rubber cables are constructed from multiple strands of copper wire, and are insulated and sheathed with rubber material, which enhances the cable&#;s flexibility, abrasion tolerance, and tear resistance.

PVC cables are generally consist of PVC-insulated copper or aluminum core, and wrapped in PVC sheath, which provides adequate electrical insulation, abrasion, and corrosion resistance for general use, but tends to be less flexible and less resistant to extreme conditions than rubber cables.

Temperature Resistance:

Rubber coated cable exhibits superior temperature resilience, capable of operating effectively under extremely high and low temperatures. Consequently, rubber cables are more aptly suited for environments experiencing significant temperature variations.

Application:

Rubber flex cables are commonly used as mobile power cords for various electrical equipment and are preferred for industrial applications, outdoor environments, power tools, extreme temperatures, or rough handling areas. PVC cables, on the other hand, are mainly used in fixed installations as cloth wires, control cables, building wires, and power cables, and are common cables for electronic equipment&#;s internal connections.

PVC wires are less expensive than rubber wires due to the relatively simple manufacturing process. This affordability is a factor that contributes to their extensive popularity.

However, it&#;s important to note that despite rubber electrical wires excelling in flexibility and handling a broader temperature spectrum, they might not match PVC wires in chemical resistance, UV protection, and flame retardancy. PVC cable and rubber cable have their own advantages, and should be selected according to the specific application. Contrary to the perception held by some that rubber signifies inferior durability or quality, and thus a safety concern, the following section addresses this misconception.

Is rubber cable safe?

Certainly, rubber cables are safe for various electrical uses. They provide good flexibility, temperature and abrasion resistance, waterproof, and high tensile strength. Their rubber insulation ensures effective electrical insulation, preventing current leakage. Additionally, the inherent flexibility and robustness of heavy duty rubber cable significantly mitigate risks associated with mechanical stress and insulation deterioration, like cracking. It is worth noting, however, that rubber cables are less flame retardant and may not be suitable for high-frequency signal transmission; in such cases, low smoke zero halogen (LSZH) cables or shielded cables are recommended.

Optimal safety can be ensured by selecting high-quality rubber cables that meet relevant industry standards and certifications, and choosing an established manufacturer such as ZW cables. Besides, correct installation methods and regular maintenance checks further ensure the safety of the rubber flex cable.
