Polycab screened cables are power cables designed with a metallic shield (screen) to minimize electromagnetic interference (EMI) and ensure signal integrity. They are commonly used in industrial and other applications where reliable power or signal transmission is crucial and external noise is a concern.

Polycab instrumentation cables are designed for transmitting low-energy electrical signals used in monitoring and controlling power systems and various industrial processes. They are crucial for applications requiring accurate and reliable signal transmission, especially in demanding industrial environments. These cables are engineered to minimize interference and ensure optimal performance in control and instrumentation systems.

Polycab speaker wires are designed for connecting audio amplifiers to speakers, ensuring clear and low-loss signal transmission. They are ideal for various applications like Hi-Fi systems, home theaters, and public address systems. These wires, often featuring high-conductivity copper and thick insulation, are engineered to minimize signal loss and maintain sound quality over time.
