What is the difference between cable BRV and RVV?

BVR is a copper-core multi-strand soft conductor PVC insulated cable, which is a single-core wire with only insulation and no sheath. RVV is a copper core PVC insulated PVC sheathed flexible cable, which should be the same thing because the frequency conversion cable must be shielded But you write it like this The previous BPYJV should not have this model Who provided it to you You have to ask him This model directly affects its structure Variable frequency power cable model representation: Project Code Description Series Code BP Frequency Conversion Cable Insulation Code YJ XLPE Insulation Sheath Code V E PVC Sheath Low Smoke Halogen-free Polyolefin Sheath Structural Features P P2 P1 P3 Copper wire or tinned copper wire Copper strip wrapping Copper wire wrapping Aluminum-plastic composite tape wrapping Flame retardant code Omitted zr wdz Non-flame retardant Flame retardant Low smoke halogen-free flame retardant.

RVV is a class I flexible wire in GB T5023 and should be certified by 3C.

BRV Cable:

b Flat or flat.

r Flexible cable structure for connection;

v Insulating PVC.

My personal opinion is as follows:

BVR: It is a single core wire;

Hehe... Hopefully! Thank you).

BRV: It is a single-core soft copper wire; RVV is polyethylene insulated polyethylene insulated sheathed soft core wire.

Landlord, did you make a mistake? brv？It should be BVR, right? The "Struggle PRR" master is great

BVR is a copper core PVC insulated flexible wire, when the standard is implemented. It is mainly used for home decoration and the laying of general electronic instruments. RVV belongs to the cable category, and the implementation standard is that it is a PVC insulated PVC sheathed insulated cable.

If you should ask RV, then it is very close to BVR, the biggest difference between the two is that RV is softer than BVR core, which is more suitable for cable connection inside the instrument. RVV belongs to the category of cables, which are multi-core cables that can be used for signal transmission.

Hello answer, I am inquiring for you here, please wait a while, I will reply to you right away RVV is a copper core PVC insulated PVC sheathed flexible cable, which is a multi-core wire (2 cores and above), with insulation and sheath.

RVV: It is also a soft-sheathed wire with two or more RV wires together.

BVR is a copper-core multi-strand soft conductor PVC insulated cable, which is a single-core wire with only insulation and no sheath.

RVV is a copper core PVC insulated PVC sheathed flexible cable, which is a multi-core wire (2 cores and above), insulated and sheathed.

RVB is a flat, unsheathed flexible wire. Commonly known as red and black (parallel) wire, it is a kind of flat unsheathed flexible wire, which is made up of a red and a black insulated copper wire to disturb the parallel insulation extruded flexible wire.

RVB two-core flat copper core polyvinyl chloride.

Insulated flexible wire is used for all kinds of mobile electrical appliances, instruments, telecommunication equipment, and automation devices.

It is also used for wiring and internal installation.

The ambient temperature is not lower than -15 during installation.

It is suitable for household appliances, small power tools, instruments, meters and cables for broadcasting and power lighting.

Product Description: The standard wire is made of multiple bare copper wires stranded with PVC insulation rated voltage.

uo u is 300 300 volts long-term allowable working temperature does not exceed 70 packaging length: 100 meters roll, 200 meters oak plum finch roll.

RVB is a flat, unsheathed soft wire, commonly known as red and black (parallel) wire.

RVVB is a copper corePolyvinyl chlorideInsulated sheathed flat power cord, suitable for household appliances, lighting, security monitoring cables, etc.

RVVB and RVV are both sheathed lines.

In terms of use, they are similar, but the difference is that the RVVB is flat and the RVV is round. At the same time, RVVB is generally only 2-core sheathed wire, while RVV has a range of cores from 2-24 cores.

RVB is used in the same way as RVVB, RVB is a flat unsheathed flexible wire, RVVB is a flat sheathed flexible wire, and RVVB has an extra layer of sheath than RVB. RVVB is a flat parallel sheathed wire, and RVS is an unsheathed twisted pair.

This is the model of the cable.

The full name is copper core conductor PVC insulated PVC sheathed flat flexible cable.

r: Represents a flexible cable, and the conductor is made of multiple strands of soft copper wire.

The first V: Cable insulation material polyvinyl chloride (PVC).

The second V: cable sheath material polyvinyl chloride.

B: Flat cable, the shape of the cable is flat, as shown in the figure below.

Flat cables.

Wire rvvb indicates:

r--- flexible cable (wire) for connection, flexible structure.

v Insulating PVC. v---PVC insulating sheath.

b Flat (flat).

The naming meaning of BV line and RV line.

BV: copper core PVC insulated wire.

RV stands for: copper core PVC insulation to connect flexible wires.

RV has a wide range of applications in the field of industrial power distribution, especially suitable for flexible installation places with strict requirements, such as electric control cabinets, distribution boxes and various low-voltage electrical equipment, which can be used for the transmission of electricity, electrical control signals and switching signals. Generally, RV wires and cables are designed with a soft structure, with a small bending radius of conductors, and are suitable for wet and oily installation sites.

BV is a single-core hard wire, and all conductors below 6 square meters are one conductor, and at least 7 wires from 10 square meters. The conductor of BV, whether it is a single core or a stranded body, is relatively hard, and the single core is relatively thick! RV is a flexible thread with many cores, as thin and soft as a human hair.

The conductor cross-sectional area varies from square to 10 square and is mainly used for connecting wires within various devices.

It can be seen that structurally, the BV wire is the same as the RV wire, the BV wire conductor is a single copper wire, and the RV wire conductor is a hinged multiple thin copper wires.

Uses of BV line and RV line.

BV: long-term allowable temperature 65, minimum temperature -15, working voltage AC 500V, DC 1000V, fixed laying indoors, outdoors, can be applied openly or covertly.

RV: The maximum operating temperature is 65, the minimum operating temperature is -15, the working voltage is AC 250V, DC 500V, which is used as the internal wiring of instruments and equipment.

To put it simply, the RV line is more suitable for special environments such as many bends and corners, or the stringing environment is more complex, and the BV line is suitable for general applications.

PS: BV, BVR and RV are these wires, but many people don't know what these letters stand for?

The letter B series is classified as cloth wires. (PS: Make an indoor power line, nail it to the wall).

The letter V stands for PVC polyvinyl chloride, which is the plastic insulation layer (PS: one V for one layer of insulation and two V for double layer insulation).

The letter L stands for aluminum wire, and the absence of L indicates copper wire.

The letter r stands for soft wire, and to be soft, it is to increase the number of conductors and reduce the diameter of each wire.

RV multi-strand soft copper wire for electrical appliances.

BV A hard copper wire is used for household lighting circuits.

RV soft copper conductor PVC insulated wire.

BV hard copper conductor PVC insulated wire.

RVVP cable: PVC insulated-PVC sheathed flexible wire with shielding. The meaning of each letter is: R - flexible wire; V-PVC insulation; V-PVC sheath; p-shield.

The main application of RVVP cable is suitable for communication, audio, broadcasting, audio system, anti-theft alarm system, intelligent automation system, automatic meter reading system, fire protection system and other anti-interference line connection, efficient and safe transmission data cable.

RVVP is a kind of soft conductor PVC insulated wire, with a shield and PVC sheath.

R is a flexible wire, B is flat, Q is light, V is PVC insulation, V is PVC sheathed, P is shielded, so RVVP refers to the copper core PVC insulated PVC sheath shielded flexible wire, and there are some other letters, for your reference. A is the installation line B refers to the insulated wire C marine cable K control cable N agricultural cable, if it is an aluminum wire there will be L marking, and the symbol T of the copper wire is omitted.

The full name of RVVP cable is copper core PVC insulated PVC sheathed shielded flexible cable. r Flexible wires.

V-PVC insulation;

V-PVC sheath; p-shielding.

RVVP: copper conductor PVC insulated PVC sheathed shielded flexible cable.
