Market Segmentation

By Material

Metal

Metal-based insulated wires and cables, primarily made of copper and aluminum, are widely used due to their excellent conductivity and durability. Copper-based cables dominate the market due to their superior performance in power transmission and electrical applications. Aluminum cables, on the other hand, are preferred for cost-effective solutions, especially in overhead power transmission lines.

Optic Fibre

Optic fibre cables are increasingly used in data transmission, telecommunications, and high-speed internet networks. The growing demand for 5G infrastructure, cloud computing, and IoT applications is driving the adoption of fibre optic cables. These cables provide higher bandwidth, faster speeds, and greater reliability compared to traditional metal-based cables.

Plastic

Plastic insulation materials, such as PVC (Polyvinyl Chloride), XLPE (Cross-linked Polyethylene), and PE (Polyethylene), are extensively used in insulated wires and cables. These materials offer flexibility, durability, and resistance to environmental factors such as moisture and chemicals. PVC cables are particularly popular in residential and commercial wiring applications, while XLPE cables are preferred in high-voltage power transmission.

By Installation
