This is a PVC-insulated single-core stranded copper wire, commonly known as BVR wire, a flexible electrical conductor widely used in low-voltage terminal wiring systems. It is engineered to deliver reliable power distribution while offering the flexibility required for complex installations.
Product Structure & Key Features
This wire features a multi-strand fine copper conductor tightly wrapped in a single layer of PVC insulation, with no additional outer sheath. The stranded copper design provides exceptional flexibility, allowing it to be easily routed around corners, through tight conduits, or in confined spaces without compromising performance. The PVC insulation offers reliable electrical insulation, moisture resistance, and basic mechanical protection, while color-coded variants help quickly identify phase, neutral, and ground wires, streamlining installation and reducing wiring errors.
Product Type & Differentiation
It falls under the flexible category of building wires, contrasting with solid-core copper wire (BV). While solid-core wires are rigid and ideal for fixed conduit installations where stability is key, this stranded variant is purpose-built for applications requiring repeated bending, frequent movement, or installation in cramped environments. It pairs seamlessly with PVC power cables to form a complete, safe electrical infrastructure for residential and commercial projects.
Material & Performance Advantages
High-purity copper conductors ensure low electrical resistance, minimizing energy loss and supporting consistent current flow for stable power delivery. The PVC insulation is cost-effective, easy to process, and highly resistant to aging, with a long-term operating temperature rating of 70°C. It also exhibits good flame-retardant properties, meeting most international indoor wiring safety standards. As one of the most versatile PVC electric wires on the market, it balances durability, performance, and affordability for diverse applications.
Common Applications
This stranded copper wire is widely used across residential, commercial, and light industrial sectors, including:
-Building lighting circuits and socket wiring
-Distribution board internal connections and control panel wiring
-Internal power connections for household appliances and industrial equipment
-Renovation projects where flexible routing is critical
It is a foundational component for projects requiring reliable terminal wiring, often combined with complementary components to build robust electrical systems.
Installation & Safety Guidelines
To ensure optimal performance and safety, follow these key installation practices:
-Control the stripping length carefully to prevent loose copper strands that could cause short circuits.
-Avoid excessive pulling, twisting, or kinking during installation to prevent damage to the fine stranded conductor.
-Keep the wire away from high heat sources, direct sunlight, and prolonged moisture exposure. Use conduits or trunking for added protection in harsh environments.
-Always comply with local electrical codes and safety standards during installation.
