The difference between BVR wire and RV wire?
The full name of RV wire is polyvinyl chloride insulated unsheathed wire, which is a single-core soft wire twisted from thin copper wires. It is a fixed wire used in home decoration. It is widely used in the industrial production and power supply industry, especially in soft installation sites with strict regulations, such as electrical cabinets, distribution cabinets and various low-voltage electrical equipment, and can be applied to power engineering and electrical control systems. Transmission of data signal and power switch data signal. RV cables are widely used in the field of industrial power distribution, especially 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 transmission of electricity, electrical control signals and switch signals . RV wire and cable adopts soft structure design, the conductor bending radius is small, and it is suitable for wet and oily installation places.
The full name of BVR wire is copper core PVC insulated soft sheathed wire. The structure is composed of insulator and conductor. It is a kind of flexible wire specially used in power distribution cabinets. Soft, so it is often used in places where soft wiring is required. It is not only convenient and quick to install, but also improves work efficiency.
Introduce in detail the similarities and differences between BVR wires and RV wires?
①The two kinds of wires belong to flexible wires, both of which are composed of multi-core copper wires, and are called polyvinyl chloride insulated flexible wires;
②The structure is very simple, and it is composed of a conductor and a polyvinyl chloride insulating layer;
③In terms of color, both of them are different colors-red, yellow, black, blue, green, and yellow-green.
①Specification: The implementation standard of BVR wire products is GJB/T 5023.3-20088734.2-2016,
The implementation standard of RV line products is GB/T 3956 Category 5 5023.5-2008;
②Working voltage: BVR wires belong to the cloth wire category, and the general rated current is 450/750V, while RV wires are mostly used inside mechanical equipment as connecting switching power cords, and the current demand is high, with 450V/750V or higher Six 00/1000V conductors: BVR conductors belong to category 2 soft conductors; RV conductors belong to category 5 conductors;
③Main use: BVR wires are mostly used as cloth wires to fix places that require softness when routing. In many cases, they can replace BV wires. After all, BVR wires are softer; RV wires are mostly suitable for various household applications. The internal connection wires of electrical appliances or mechanical equipment are often used in security monitoring equipment and instrumentation equipment, so RV wires are softer, so they are also known as electronic wires.
④Temperature: The operating temperature of the basic BVR wire cannot exceed 70°C, and the RV wire can reach 80°C. Of course, if there are special requirements, heat-resistant types can be purchased.
⑤ Surface: From the surface, there are differences between the two. The copper wire of the RV wire is thinner than the copper wire of the BVR wire, so the material of the RV wire is softer than that of the BVR wire.
What are the advantages of RV wires:
1. High insulation resistance and withstand voltage strength;
2. Good heat aging resistance, low temperature performance and chemical resistance;
3. The cable is light in weight and easy to use and lay;
4. Excellent electrical conductivity, not easy to generate heat, and long life.
