What kind of cable is VV, is it copper or aluminum? Urgent!

The first V: Inner layer PVC insulation.

The second V: the outer PVC sheath.

Rated voltage to ground (metal shield), rated voltage between wires 1kv4 25: Four 25mm wires.

This is a copper core, if it is an aluminum core, you need to add L (the pinyin initials of aluminum) between the two Vs to become: VLV

Its cross-section is similar to the following figure (black, red, yellow, green, and blue are all made of polyvinyl chloride, and the four copper cores are the same thick, all of which are 25 square millimeters).

This is the specification model of the cable.

Split down for better understanding.

VV (model): copper core conductor polyvinyl chloride.

Insulated (first v) PVC sheathed (first v) power cable.

Cable voltage rating.

4 25 (specification): 4 core cables, each cable core has a cross-sectional area of 25 square millimeters.

VV is a copper core cable, cable type.

The default is copper, and the model of the aluminum core is VLV

VV cable is a very commonly used one of the power cables, its role is the same as YJV cable most of the time, although the overall performance is not as good as YJV cable, and is gradually replaced by YJV cable, but because of its relatively low price, it has been widely used in many fields, VV cable full name copper (aluminum) core PVC insulated PVC sheathed power cable, an important member of the power cable, the two letters V represent the insulation and sheath of the material are PVC;

The second V is the cable sheath material, which is also PVC, and the full name of the VV cable is called copper core PVC insulated PVC sheathed power cable.

The components from the inside to the outside are the conductor, the insulating layer, the filling layer, the (steel strip layer), and the sheath layer. It is generally used as a power transmission hub, often buried in the soil or laid indoors, trenches, and tunnels. The cross-section includes from mm2 to 400mm2, and the number of cores includes single core, 2 cores, 3 cores, 4 cores, and 5 cores 1.

VV cable is a very commonly used one in power cables, the first V is the main insulation material of the cable is PVC PVC which means plastic, and the second V is the cable sheath material is also PVC. It is generally used as a power transmission hub, often buried in the soil or laid indoors, trenches, tunnels, with a small insulation distance between lines, no towers, less land occupation, and basically no space on the ground.

RVV wire is composed of adding a layer of sheath outside the RV wire, which belongs to the sheathed wire, and the number of cores is not fixed, generally in two or more, so it is also known as multi-strand copper core flexible wire, the letter R represents the flexible wire, and the letter V represents the insulator, that is, polyvinyl chloride, that is, PVC, in the weak current system, the RVV wire is the most commonly used.

The full name of RVV cable is copper core PVC insulated PVC sheathed flexible cable, also known as light PVC insulated poly, commonly known as soft sheathed wire, which is a kind of sheathed wire. RVV wires and cables are two or more RV wires with a sheath. RVV cable is the most commonly used cable in weak current system, the number of cores is indefinite, two or more, there is a PVC sheath on the outside, and there is no special requirement for the arrangement between the cores.

The letter R stands for Cord and the letter V stands for Insulator Polyvinyl Chloride (PVC).

RVV cable: a type of sheathed wire.

VV cable is a copper conductor PVC insulated and PVC sheathed power cable, the two letters V represent the insulation and sheath materials are PVC. The first V is the main insulation of the cable, and the material is PVC polyvinyl chloride, which means plastic. The second V is the cable, and the sheath material is also PVC.

VV cable is a very commonly used power cable, its role is the same as YJV cable most of the time, although the overall performance is not as good as YJV cable, and is gradually replaced by YJV cable, but because of its relatively low cost, it has been widely used in many fields.

Generally, Yuhu is used as a power transmission hub, often buried in the soil or laid indoors, ditches, tunnels, small insulation distance between lines, no towers, less land occupation, basically do not occupy space on the surface.

<>VV cable is a kind of power cable, the full name is copper conductor PVC insulated and PVC sheathed power cable. The first V in VV cable means insulation, because the main material of VV cable is PVC polyvinyl chloride, so it has the characteristics of insulation. The second V in the VV cable is the meaning of the cable, the VV cable has a protective sleeve on the outside, and the raw material is also PVC PVC, so it can also be insulated.

VV cables are generally laid indoors or buried in the soil in daily life, and are mostly used for the location of force transmission hubs, and can also be seen in the construction of tunnels and trenches. VV cable has the advantages of reducing the insulation distance between lines, reducing the land occupation, not occupying ground space, and avoiding the construction of towers.

The first V is the main insulation of the cable, and the material is polyvinyl chloride; The second V is the cable, and the sheath material is also PVC.

The full name is called copper core conductor PVC insulated and PVC sheathed power cable.

Product structure: The components from the inside to the outside are the conductor, the insulating layer, the macro pre-filling layer, and the sheath layer. The most commonly used conductor material on the market today is copper conductor; The insulation layer and outer sheath material are polyvinyl chloride, that is, polyethylene chloride masking plastic; The filling layer is generally some soft nylon material, in order to prevent the direct contact and extrusion between the internal conductors of the cable; The role of steel belt armor is compression-resistant, and it can be used for burial.

<>1. The RVV cable is a copper Chang disturbing core PVC insulated PVC sheathed flexible wire and cable.

2. R is the meaning of soft wire, V is insulator, RVV cable is only composed of a layer of sheath outside the wire, the number of core wires inside is not fixed, generally in more than two, people also call Zixun Cong It is a multi-strand copper core flexible wire, in the weak current system, RVV wire is also commonly used to a.

The full name of RVV wire is copper core PVC hail pat insulated PVC sheathed flexible wire, also known as light PVC sheathed soft wire, commonly known as soft sheathed wire, which is a kind of sheathed line.

It is mainly used in power cords, control lines and signal transmission lines for electrical appliances, instruments, electronic equipment and automation devices, and can be used for burglar alarm systems, building intercom systems, etc.

R represents flexible cable, the first V represents polychloride vinyl insulation, and the second V is PVC sheath.

The full name is: copper core conductor PVC insulated PVC sheathed flexible cable, there is no conductor material in the model, and the default is copper.
