Reasons Why BV Wiring Is Suitable for Home Renovation
Choosing the right household wiring is extremely important. If the quality of the wires is not guaranteed, it will directly affect our daily use. Among the many types of home installation cables available, BV wire is one of the most commonly used for residential wiring—so many professionals recommend BV wire as the preferred choice for home electrical installations. So why is BV wire well suited for home wiring? Let’s first look at the reasons why BV wire is ideal for home renovations.

The Five Major Categories of Common Wires and Cables
In everyday life, common wire and cable products can be broadly categorized into the following five types: bare wire products, power cables, flat cables, communication cables and optical fibers, as well as winding wires. (1) Bare wire products are characterized by their pure conductive metal core, lacking both insulation and sheathing layers. Examples include steel‑core aluminum stranded wire, copper‑aluminum busbars, and electric locomotive overhead contact wires—all of which fall under the category of bare products. These products are primarily used in suburban and rural areas, on main user lines, in switchgear, and other similar applications. The majority of their manufacturing processes involve pressure working techniques such as melting, rolling, drawing, stranding, and compacted stranding.

Characteristics of Eco-Friendly Home Wiring
Advantages: The wire is relatively soft and is often used in temporary power applications. It significantly reduces requirements for installation angles and is well suited for bending and conduit routing. Disadvantages: It has a short service life, oxidizes rapidly, and is prone to issues such as broken conductors and localized overheating, necessitating timely replacement. Given that concealed wiring in electrical circuits is a hidden project, BV wire—typically with a longer service life—is generally preferred.

Flexible Mineral-Insulated Fire-Resistant Cable Support Bracket
What regulations must flexible mineral-insulated fire-resistant cable support brackets comply with? The brackets shall meet the following requirements: 1. The surface shall be smooth and free of burrs. 2. They shall be durable and stable, suitable for the intended service environment. 3. They shall provide the required load-bearing capacity. 4. They shall satisfy the fire protection requirements of the project. Metal cable supports shall undergo corrosion‑protection treatment and shall comply with the following provisions: 1. For high‑capacity power plants and other locations with dense cable installations, as well as for critical circuits, steel cable trays should be equipped with corrosion‑protection treatments that offer long‑term durability, selecting appropriate corrosion‑protection methods based on the project’s environmental conditions and durability requirements. In highly corrosive environments, it is advisable to use corrosion‑protection treatments with higher durability, such as hot-dip galvanizing.
