Cables by Type

Secondary Type URD Cable

Secondary Type URD Cable is commonly used in applications requiring one, two, three, or four electrical pathways. These conductors serve as the primary routes for transmitting electrical power in distribution systems, running side by side throughout the length of the cable. Our comprehensive range of wires and cables ensures reliability, safety, and compliance with international standards.

Our URD cables are engineered with high conductivity to ensure efficient power transmission. They are well-insulated to provide electrical insulation and protection from environmental factors. Additionally, some cables feature an outer jacket for added mechanical protection and resistance to moisture and abrasion. Available in various sizes and types, they suit different applications. Each product complies with international standards for safety and performance.

Applications

● Individual Service Lines: Providing dedicated power lines from distribution transformers to individual residential or commercial buildings.

● Secondary Distribution Lines: Connecting secondary distribution transformers to primary distribution lines.

● Temporary Installations: Utilized as temporary power lines during construction projects or emergency situations.

● Dual Service Lines: Providing two separate power lines from distribution transformers to individual residential or commercial buildings.

● Multiple Service Lines: Providing three separate power lines from distribution transformers to individual residential or commercial buildings, allowing for distinct power circuits.

Secondary Type URD Cables Construction

Secondary Type URD Cables are constructed with the following key components:

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

● Insulation: Materials such as PE (polyethylene) and XLPE (cross-linked polyethylene) are used to insulate the conductors, ensuring electrical safety and durability.

● Sheathing: Additional protective layers, such as PVC (polyvinyl chloride) or PE (polyethylene), are applied to some cables to provide mechanical protection and enhanced safety in case of fire.
