VFF Double Core PVC Insulated Cable

When sourcing reliable electrical wiring for appliances, lighting, and internal power connections, our Japanese standard flat twin core cables are engineered for superior performance and safety. For applications requiring a compact, durable solution, our Japanese VFF Flat Twin Core Wire offers excellent flexibility and insulation. For enhanced durability and flame retardancy in more demanding installations, consider our robust Japanese VHF PVC Insulated Flat Cable. Both variants provide the trusted quality associated with PVC Insulated Japanese Flat Twin Wire, ensuring consistent electrical characteristics and physical protection. This Japanese Style Double Core Flat Wire is designed to meet stringent international and Japanese electrical standards, making it a preferred choice for OEMs, electricians, and manufacturers globally.


The VFF Double Core PVC Insulated Cable is specifically designed for 300/500V applications, offering a reliable and safe wiring solution for a wide range of electrical equipment. Its flat, parallel construction allows for easy installation in tight spaces and provides excellent heat dissipation. The primary conductor is made from high-purity annealed copper, ensuring optimal conductivity and minimal power loss. This conductor is then insulated with a high-grade Polyvinyl Chloride (PVC) compound, which provides excellent resistance to abrasion, acids, alkalis, and moisture. The PVC insulation is also self-extinguishing and features low smoke emission, enhancing safety in case of fire. The two insulated cores are laid parallel and bonded together, creating a flat, stable profile that is easy to route and secure.

Key technical specifications and performance characteristics of the VFF Double Core PVC Insulated Cable are detailed below:
