BV cable is a single-core rigid cable commonly used in home renovations. The N-BV cable specification is also known as fire-resistant cable. This is a simple addition to BV cable, adding a fire-resistant material. This gives N-BV excellent fire resistance, while also improving safety and service life. Due to its special properties, enhanced safety and reliability, it is often used in demanding and specialized applications.
N-BV Cable
1. N-BV Cable: Fire-resistant copper-core PVC insulated flexible cable. It is simple to understand that N-BV is a BV cable with an additional layer of fire-resistant material. N-BV cable is often used in areas with a high risk of fire or where fire resistance is a high priority.
2. The fire-resistant material of N-BV cable is made of glass fiber braided fluorphlogopite tape, processed through a special process. Its main features include high-temperature resistance, insulation, fire retardancy, and corrosion resistance. The fire-resistant layer is generally wrapped around the conductor surface. Fire-resistant layers can be categorized as single-layer or double-layer depending on the fire resistance requirements. Naturally, fire resistance performance also varies depending on the type of layer.
N-BV Cable Applications
1. Many people believe that fire-resistant wire is incombustible. This is a complete misunderstanding. Fire-resistant wire is a result of a special process applied to both the insulation and the conductor. This ensures that, when a fire breaks out, it only reaches a certain temperature before it breaks down. This prevents power outages immediately, allowing time for evacuation. This is a key advantage of N-BV cable, making it a highly suitable choice for specialized locations.
Applications: It is typically installed in fixed locations, flame-resistant, and free of harmful or toxic gases. This product is used in various electrical installations requiring fire resistance in specialized environments, such as metallurgy, thermal engineering, petroleum, chemical engineering, natural gas, and kerosene. Its fire resistance temperature typically reaches over 1,000 degrees Celsius.
The above explains N-BV cable from two perspectives, now moving on to household wiring. What needs to be mentioned is that in order to improve our safety awareness, the editor here reminds everyone: when purchasing fire-resistant wires, please make sure whether the product has the national mandatory 3C certification, whether the merchant has all kinds of certificates, and whether the merchant can guarantee the safety performance of the fire-resistant wire. Combining various situations can help us choose high-quality cable products.
