What Are The Differences Between Sheath Line And Ordinary Wire?

Sheathed wire is actually a wire made of two or three single-core wires combined with an insulating sheath. Not only can it be a BV line, but also a BVR line. Three or two parallel BV wires are coated with an insulating layer. Common PVC sheathed wires are represented by letters with two V, such as BVV, H05VV-F wires, because one V represents the insulation layer is PVC material, and the other V represents the sheath layer is PVC material. After adding this layer of insulation, it is the sheathed wire. The sheathed wire is also one of the necessary wires for most households, usually consisting of three or two cores.

Classification of sheathed wires:

There are many types of sheathed wires, which can be divided into nylon sheathed wires, rubber sheathed wires, cross-linked sheathed wires, armored sheathed wires and PVC sheathed wires, depending on what material is used for the sheath, the shape different from hardness, for example, RVV sheathed wire and hard sheathed wire are BVV wire, while BVVB is flat wire. Anyway, the shape of the appearance is different, they are called sheathed wires.

The role of the outer sheath of the wire:

Because the current home improvement, generally use the wire tube to lay the wire, and then use the wire tube to lay 3 copper wires (fire wire, neutral wire, ground wire). Because the sheathed wire has one more insulator than the ordinary wire, it is relatively safe during use, so it is more useful in the field of home improvement of buildings. Most people use sheathed wire to make power cords. In past home renovations, sheathed wires were used as lighting and power wires that could be buried directly on the wall or fixed to the wall. The advantage is that it can be laid without pipes or grooves, which is very economical. The sheath of the wire acts as protection for the replacement tube and groove and is the outermost layer of the sheath insulation. It is convenient and quick to lay, beautiful and elegant, and safe to use. It is the choice for connecting electrical appliances such as household mobile power strips, refrigerators or air conditioners.

What are the general sheathed wire models?

Our common copper core sheathed wires are generally: BVV, RVV, KVV, BVVB, RVVB, mainly because the copper core sheathed wires in the letters do not have L, because L means aluminum. According to its use environment and specific requirements, it can also be divided into round sheathed wire and flat sheathed wire. The round sheathed wire is a multi-strand copper core structure, and the flat wire is generally composed of a single conductor.

What is the difference between ordinary wire and cable and sheathed wire?

Because the sheathed wire can actually be understood as two or three parallel BV wires, photovoltaic cables, H05RN-F cables, H07VV-K wires and nylon cables, cross-linked polyethylene and polyurethane sheathed wires and so on. The BV line originally had only one layer of insulation, so three or two parallel BV lines were combined with a layer of insulation on the outside. The outermost insulating layer is the sheathed wire. No matter what the occasion, copper core sheathed wire is one of the commonly used wires, usually composed of three or two cores.

Finally, the term of sheath in the cable industry can represent different types of wire and cable products, but there are more models called sheathed wires, which sound better in resolution, such as: nylon sheathed wire, rubber sheathed wire, RVV sheath Lines, etc. With such a concept, the understanding of sheathed lines will be much better.
