Rigid and flexible PVC cable are widely used for many different occasions according to people’s preferences. These two kinds of wires are different in their hardness, but most of them are similar in their use environment and voltage. There are just subtle differences between the two in small usage details. Regarding these two kinds of PVC wires, many people want to know the differences between them. This article will introduce this point to you.
There are mainly three different parts to this article:
Now, we will introduce the first topic of this article, explaining the concept of rigid and flexible PVC cables.
Electric wire specifications usually use the conductor section area to express. According to the different conductor structures, PVC wire includes rigid PVC wire and soft PVC wire. Rigid PVC copper wire uses a single solid copper as a conductor. Its biggest feature is solid, it is a little hard to bend, and the conductor is only one strand of copper, this copper diameter changes according to the wire section area. For example, if the cable specification is 1.5mm2, then the copper diameter is 1.38mm, if the cable specification is 4.0mm2, then the copper diameter is 2.25mm, if the cable specification is 10.0mm2, then the copper diameter is 7 strands with 1.35mm. That means, this rigid wire copper strand is thicker, so it can’t be bent any way you want, so in the electric industry, it will have some limitations since a solid conductor.
In the market, the commonly used rigid copper electric wire is BV cable, KVV cable, YJV cable, YJLV cable, etc.
Now, Let’s explain what is soft PVC wire.
Different from rigid PVC wire, flexible PVC wire conductor includes multi-strands soft thinner copper, this structure makes it soft and flexible. Compare with rigid wire, flexible PVC copper wire can meet bending requirements. In electric installation, it can suitable for any using environment, especially for occasions that need bending, it is easier to install than rigid wire.
In the market, soft copper cable usually includes BVR cable, rvv control cable, rvvp control cable, rv cable, rvs fire alarm cable, etc.
After understanding what is rigid and flexible PVC electric cables, we will enter into the main topic, the differences between them. After knowing this, you will also know how to choose them. Let’s take the commonly used BV solid wire and BVR soft wire as an example.
Here is a picture table that can show their specific differences in performance.
Now, do you understand the differences between rigid and flexible PVC cables? If you still have any problems, please kindly contact Henan Shenbei Industrial Co. Ltd. for consulting.
