When it comes to single-core rigid cable, the first thing that comes to mind is BV cable. BV cable stands for Copper Core Polyvinyl Chloride Insulated Cable. As the name suggests, BV cable is copper wire. Anyone who has shopped for electrical wiring knows that copper wire is excellent for household wiring, offering advantages in both conductivity and longevity. Today, we'll focus on BV cable and its uses.
1. BV Nomenclature:
BV cable is short for plastic copper wire and stands for single-core general-purpose rigid conductor unsheathed power cable.
BV is the abbreviation for BTV: B stands for category: distribution line, T for conductor: copper, and V for insulation: polyvinyl chloride.
2. Characteristics of BV rigid cable:
It is acid- and alkali-resistant, oil-resistant, moisture-resistant, and mildew-resistant.
3. Common BV Wire Diameter (Square Dimensions):
Common BV wire sizes include: 0.75 mm², 1 mm², 1.5 mm², 2.5 mm², 4 mm², 6 mm², 10 mm², 16 mm², 25 mm², 35 mm², 50 mm², 70 mm², 95 mm², 120 mm², 150 mm², 185 mm², and 240 mm².
4. Common BV product colors include: yellow, red, black, green, and blue (ground wire is generally yellow and green).
Wire used in renovations: BV/BVR lighting wire should be 1 to 1.5 mm², socket wire should be 2.5 mm², and air conditioning wire should be no less than 4 mm². 4 mm² or larger is recommended. Ground wires should be yellow-green, and switch wires should be red, yellow, blue, green, and black.
Applications of BV wire
Suitable for cables and wires used in power plants, household appliances, instrumentation, and telecommunications equipment, such as distribution boxes, with AC voltages of 450/750 V and below.
Ordinary insulated wire, also known as household wiring, is the most commonly used type of wire. For a new 100-square-meter home, for example, 200 meters of 4-square-meter copper-core BV wire, 400 meters of 2.5-square-meter wire, 300 meters of 1.5-square-meter wire, and 100 meters of 1.5-square-meter copper-core BV two-color wire are available. This applies to homes without suspended ceilings. If a suspended ceiling is required, 1.5-square-meter wire will require more. BV wire diameters are available in several sizes: 0.2, 0.3, 0.4, 0.5, 300, and 400 square meters.
BV wire is a harder single-core, rigid wire. Due to its hardness, it has a long lifespan and is less susceptible to oxidation. Its price is slightly lower than that of multi-core, flexible copper wire. Clearly, BV wire has its advantages, so you can choose the right one based on your needs. Of course, there are many different specifications and models of rigid wire. The above introduction to single-core rigid wire only covers the more typical and widely used BV wire. A more comprehensive understanding requires more research.
