Cables by Type

Low Voltage Cable

Low voltage cables are essential components for the transmission and distribution of electrical power in various applications, typically designed for voltages up to 1 kV. These cables are engineered to ensure reliable performance in both residential and commercial settings, providing the necessary power for a wide range of electrical devices and systems.

Low voltage cables boast several key features, including high electrical insulation, robust mechanical properties, flexibility, and resistance to chemicals and environmental factors. These attributes make them suitable for a wide range of applications. In residential buildings, low voltage cables are used for lighting, heating, and powering household appliances. In commercial settings, they are employed in office buildings, retail spaces, and industrial facilities to power equipment, lighting systems, and other essential electrical devices. They are also widely used in infrastructure projects, such as transportation systems and public utilities, ensuring a stable and efficient power supply.

Construction

● Conductor: Typically made from high-quality copper or aluminum, providing excellent electrical conductivity and mechanical strength.

● Insulation: Materials such as PVC (Polyvinyl Chloride), XLPE (Cross-Linked Polyethylene), and thermoplastic compounds ensure electrical safety and durability.

● Sheathing: Additional protective layers, such as PVC (Polyvinyl Chloride) or PE (Polyethylene), provide mechanical protection and enhanced safety in case of fire.

● Armoring: For certain applications, cables may include steel wire armoring (SWA), aluminum wire armoring (AWA), or Steel Tape Armour (STA) for additional mechanical protection.
