N-BV is a single-strand rigid wire with fire-resistant properties. It's based on ordinary BV wire with the addition of fire-resistant materials, giving it even better fire resistance. So what are the differences between them? What are the advantages of N-BV over BV? Let's take a look.
What's the difference between N-BV and BV wire?
BV is a single-core rigid wire commonly used in home decoration. N-BV, also known as fire-resistant wire, is based on BV wire with the addition of fire-resistant materials, giving it excellent fire resistance and extending its safety and service life.
N-BV wire stands for fire-resistant copper-core PVC insulated flexible cable. As the name suggests, it's based on BV wire with an additional layer of fire-resistant material. N-BV wire is often used in areas with a high risk of fire or where fire resistance is a high priority.
What are the advantages of N-BV over BV cable?
N-BV cable's fire-resistant material is made from fire-resistant polyvinyl chloride (PVC) through a special process. Its key features include high-temperature resistance, insulation, fire retardancy, and corrosion resistance. The fire-resistant layer is typically wrapped around the conductor. The fire-resistant layer can be either single-layer or double-layered, depending on the fire resistance requirements. Of course, the fire resistance performance varies depending on the type of layer.
Many people misunderstand fire-resistant wire, believing it to be incombustible. This is a complete misunderstanding. Fire-resistant wire is made by applying a special process to both the insulation and the conductor. This prevents it from breaking down in the event of a fire. This prevents power outages from occurring immediately, allowing time for evacuation.
Applications: Typically designed for fixed installation, flame-burning, and no harmful gases. This product is suitable for use in various electrical installations requiring fire resistance in specialized environments such as metallurgy, thermal engineering, petroleum, chemical engineering, natural gas, and kerosene. Fire-resistant temperatures generally reach over a thousand degrees Celsius.
To enhance safety awareness, we remind everyone that when purchasing fire-resistant cable, please carefully check whether the product has the mandatory 3C certification, whether the merchant has all necessary certifications, and whether the merchant can guarantee the safety performance of the fire-resistant cable. These factors can help you choose high-quality cable products.
