H07V-R Wire Tips: How to use them correctly?

BVR wire refers to "Bare Copper Conductor, PVC Insulated, Flexible" (bare copper conductor, PVC insulated, flexible) wire, which is a commonly used electrical installation wire. 

BVR wire features include:

  Material  : The inside is multiple strands of bare copper wire, and the outside is wrapped with polyvinyl chloride (PVC) insulation layer.

  Flexibility  : Due to the use of multiple strands of copper wire, it has good flexibility and bending properties, suitable for use in places where frequent movement is required or space is limited.

  Weather resistance  : PVC insulation material has good weather resistance and chemical corrosion resistance, and can maintain stable performance in a variety of environments.

  Scope of application  : Widely used in home, office, factory and other places of power wiring, but also suitable for control circuits and signal transmission lines.

  Color coding  : BVR wires usually have a variety of colors, different colors represent different uses, such as brown is often used for fire wire, blue is used for neutral wire, yellow green is used for ground wire and so on.

    When selecting and using BVR wires, factors such as wire specifications (such as cross sectional area) and rated voltage should be considered according to actual needs to ensure safety and compliance with relevant standards. If it is used in a specific occasion or special environment, additional protective measures need to be considered.

BVR wire has been widely used in many occasions because of its good flexibility and easy installation. Here are some of the main application areas for BVR wires:

1. Home Decoration :

 BVR wires are often used for wiring inside homes, including the connection of electrical appliances such as lighting, sockets, and air conditioners. Especially in places where frequent bending or complex wiring paths are required, such as connections to kitchens, bathrooms, or smart home devices, the flexibility of BVR wires makes them ideal.

2. Fixed wiring :

 Although the BVR wire is known for its flexibility, it can also be used for fixed wiring in some cases, especially in those occasions that require a certain degree of flexibility, such as the main trunk arrangement from the distribution box to the room, if the wiring path is more complex, the BVR wire can provide better adaptability.

3. Power cord for mobile devices :

 For household appliances that need to be moved, such as vacuum cleaners, washing machines, etc., BVR wires are ideal. These devices need to be moved frequently during use, and the flexible BVR wire can adapt to multiple bending and winding, extending the service life of the wire.

4.Low voltage lighting and control line :

 In lowvoltage lighting systems and control lines, because the current to be transmitted is small, and the wiring path is usually more complex, the multicore structure of the BVR wire not only improves the antiinterference ability, but also better protects the internal conductors and ensures the stability of the circuit.

5. Industrial and Automation Equipment :

In industrial production and automation equipment, BVR wires are widely used for the connection of sensors and controllers, as well as the internal wiring of electrical equipment. Its good flexibility and antiinterference performance make it able to adapt to the complex and changeable wiring needs in the industrial environment.

6. Transportation Facilities :

In modern transportation systems, such as subways, highspeed trains and airports, the application of BVR wires can effectively reduce the risk of fire and improve safety, especially when the wires need to pass through narrow or curved Spaces, the flexibility of BVR wires is particularly important.

7. Building Electrical Engineering :

 In construction projects, especially large public buildings, commercial buildings, etc., BVR wire is the preferred material in electrical installation due to its flame retardant performance and high temperature resistance. This type of wire can ensure that in the event of a fire, the flame is not easy to spread, thus protecting the safety of people in the building.

In summary, because of its many advantages, BVR wire is widely used in many fields such as home, industry, and transportation, and has become an indispensable part of electrical installation.
