Wires and cables have become an indispensable part of our lives. With the improvement of our living standards, almost every household is inseparable from the use of electricity. So how should we choose and purchase them? BV wire is often used in home renovations. So, are there some things to consider when purchasing BV wire? Let's take a look!
How to Choose Wire?
According to standards, wire surface markings should be continuously marked with the manufacturer's name, model number, and rated voltage. This helps to quickly identify the manufacturer in the event of problems during use, so consumers should pay attention to this when purchasing wires. Also, consumers should ensure that the manufacturer's name, model number, and rated voltage indicated on the certificate of conformity match the printed markings on the wire surface to prevent counterfeit products.
Wire Appearance - Consumers should ensure that the wire's appearance is smooth and flat, with no damage to the insulation and sheath, clear markings, and no greasy feeling when touching the wire. Looking at the cross-section of the wire, the insulation or sheath thickness should be uniform across the entire circumference, with no skewness. The insulation or sheath should maintain a consistent thickness.
How to Choose BV Wire and Cable?
BV is a PVC-insulated, unsheathed wire and cable. The specifications and rated voltage are 60227IEC01(BV)450/750V 1.5-95, and the production standard is GB/T5023.3-2008/IEC 60227-3:1997.
The square copper core wire has a wire diameter of 7/1.35mm, an outer diameter of 6.1mm, and a sheath thickness of 1.0mm. It is suitable for socket cables, utility cables, and power cords.
The wire insulation is made of environmentally friendly PVC, which is safe, fire-resistant, and extinguishes immediately when exposed to open flames. The conductor is made of 99.99% oxygen-free copper, resulting in a shiny copper wire with low resistivity, excellent conductivity, and high safety.
General-purpose, single-core, rigid-conductor, unsheathed wire suitable for instrumentation with AC voltages up to 450/750V. The maximum conductor temperature during normal use is 70°C. It's suitable for fixed wiring of electrical instruments, power lighting, and other applications. Smaller sizes are primarily used for concealed wiring in construction projects and home renovations.
The above are some important precautions regarding electrical wiring and BV wire and cable. To ensure proper wiring installation, be sure to hire a professional. Wiring installation is a crucial step in your home. Improper installation can lead to future rework, so homeowners must exercise caution and pay attention to the following steps during installation.
