Do you know what copper core wire is? Copper core wire is an indispensable component of home decoration. It's the common insulated wire and home wiring we use in our daily lives, and it's a common type of wire. It's resistant to alkalis, oils, moisture, and mildew. So how should you choose and purchase copper core wire, and what are the key points to consider? Let's take a look.
What is BV copper core wire?
BV is a PVC insulated, unsheathed wire and cable. Its model specifications and rated voltage are 60227IEC01 (BV) 450/750V 1.5-95, and it's manufactured in accordance with GB/T5023.3-2008/IEC 60227-3:1997.
This 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's suitable for socket cables, utility cables, and power cords.
The wire insulation is made of environmentally friendly polyvinyl chloride, which is environmentally safe, fire-resistant, and extinguishes immediately when exposed to open flames. The conductor is made of 99.99% oxygen-free copper, boasting a shiny surface, low resistivity, excellent conductivity, and high safety.
General-purpose single-core, rigid-conductor, unsheathed wire, suitable for instrumentation with AC voltages of 450/750V and below. The maximum conductor temperature during normal use is 70°C. It is suitable for fixed wiring of electrical instruments and power lighting. Smaller sizes are primarily used for concealed wiring in construction projects and home renovations.
What are some tips for purchasing BV copper-core wire?
According to national standards, wire surface markings must include a continuous marking of the manufacturer's name, model number, and rated voltage. This facilitates easy identification of the manufacturer in the event of problems during use, so consumers should be aware of this when purchasing wire. Consumers should also ensure that the manufacturer's name, model number, and rated voltage indicated on the certificate of conformity match the printed markings on the wire to prevent counterfeit products. Wire Appearance - When purchasing wires, consumers should pay attention to the appearance of the wires. They should be smooth and flat, with intact insulation and sheathing, clear markings, and no greasy feeling when touching the wires. Looking at the wire's cross-section, the insulation or sheath thickness should be uniform across the entire circumference, with no skewness. The insulation or sheath should also have a certain thickness.
The above is an introduction to BV copper-core wires. I believe everyone is familiar with them. Because of their acid, alkali, oil, moisture, and mildew resistance, BV copper-core wires are suitable for power equipment, household appliances, instruments, and telecommunications equipment with AC voltages of 450/750V and below. When purchasing wires, be sure to purchase genuine, authentic wires to avoid counterfeit or inferior products that could lead to electrical hazards.
