Both BVV and BVR are popular wires in the wire and cable industry, primarily used for home renovations, hence the name "home decoration wire." However, given these two widely used wires, each offering its own advantages, how should we choose? Below, we'll explain what BVV is and what it is, as well as the differences between these two types of wire, to help you choose.
BVV Wire Overview
1. Definition: BVV is the full name for copper-core PVC-insulated, rigid-sheathed wire, commonly known as sheathed wire, rigid-sheathed wire, and power cord. It is suitable for installation in electrical appliances with an AC rated voltage of 450/750 volts or less. The permissible operating temperature must not exceed 70°C for extended periods. Common cross-sectional specifications include: 0.75 square, 1 square, 1.5 square, 2.5 square, 4 square, 6 square, 10 square, 16 square, and 25 square. Larger sizes are usually manufactured by the manufacturer.
2. Characteristics of BVV cable
(1) The long-term allowable operating temperature of the cable shall not exceed 70°C
(2) During short circuit (duration shall not exceed 5 seconds), the temperature of the cable conductor shall not exceed 150°C
(3) The ambient temperature during cable laying shall not be lower than 0°C
(4) Classification and use: Used to distribute current, belongs to the distribution line category, and is represented by the letter "B"
(5) Copper conductor material is used, represented by the letter "t"
(6) The insulation material is polyvinyl chloride, represented by the letter "V"
3. Use of BVV hard wire
BVV hard wire has the characteristics of flame retardancy, fire resistance, low smoke, and halogen-free. It is suitable for fire protection systems, residential buildings, commercial buildings, and industrial distribution lines. The Difference Between BVV and BVR Wire
BVV, commonly known as hard wire, consists of a single-core round wire and a double-core flat wire. These wires have both insulation and a jacket, and are often used for bare wire applications. BVR, commonly known as flexible wire, is a single-core wire consisting of multiple strands of conductors with insulation but no jacket. It is commonly used for electrical connections and minor movements.
In wire type, the letter R stands for flexible wire and the letter B for hard wire. Simply put, BVV and BVVR are hard and flexible wires. Regarding choosing the right wire, the above information is only a guide. The specific selection process should be tailored to your individual household's electrical needs. Choosing the right wire is crucial, and I hope this article will be helpful.
