BVV and BV are rigid conductor insulated wires with a rigid conductor structure, making them easy to lay through pipes. However, they lack flexibility, especially those with large cross-sections that are difficult to bend, and are generally used for fixed installations. So, what are the differences between BVV and BV wires? Let's analyze them in detail.
What are the differences between BVV and BV?
BVV copper-core PVC-insulated and sheathed wires, commonly known as sheathed wires, are used for household power cords. Single-core wires have a round structure, while multi-core wires have a flat structure. They are suitable for cables and wires used in power plants, household appliances, instruments, and telecommunications equipment with AC voltages of 450/750V and below. They are also suitable for surface-mounted wiring. The permissible long-term operating temperature of the wire cores does not exceed +65°C. According to standards, BVV wires have 2-5 cores and a nominal cross-section ranging from 0.75 to 10 square meters, with seven specifications: 0.75, 1.0, 1.5, 2.5, 4, 6, and 10.
BV copper-core PVC-insulated rigid wire is a general-purpose, single-core, rigid-conductor, unsheathed wire. The B series is a type of cloth wire, a plastic copper wire suitable for power plant wiring at voltages of 450/750V and below, and is widely used in home wiring. Common specifications include 1.5, 2.5, 4, 6, 10, 16, 25, and 35 square meters.
BVV and BV cables share similarities: they are flame-retardant, fire-resistant, and low-smoke, halogen-free.
What is the difference between cables?
There's no strict distinction between wire and cable. Generally, products with a small number of cores, a small diameter, and a simple structure are called wires. Those without insulation are called bare wires, and the rest are called cables. Conductor cross-sectional areas larger (greater than 6 square millimeters) are called large wires, while those with smaller cross-sectional areas (less than or equal to 6 square millimeters) are called small wires. Insulated wires are also called cloth wires.
The above is about the difference between BVV and BVV wires. I believe everyone has some understanding of the differences and advantages of the two. BVV wires and BV wires are similar in name, but they represent different meanings: BVV is a copper core PVC insulated sheathed insulated wire, and BV is a copper core PVC insulated hard wire. They are used in different occasions and need to be judged according to the specific use environment! We can choose according to our actual needs.
