The underground residential distribution (URD) wire incorporates a conductor crafted from compressed strands of aluminum alloy from the 1350 series. Its insulation is comprised of black cross-linked polyethylene (XLPE), offering robust protection. The phase conductors are then bundled together with neutral conductors, forming a twisted bundle that is commonly employed in underground electrical wiring systems. You'll frequently find this cable in light- to medium-duty commercial applications, and it's also a popular choice for powering underground residential areas. With a voltage rating of 600v, it's suitable for a wide range of uses.
This URD cable adheres to the stringent standards set by Underwriters Laboratories and the Insulated Cable Engineers Association (ICEA), ensuring its quality and reliability. It can be installed either within ducts or buried directly, making it suitable for both wet and dry environments. Its high resistance to scratching and abrasion means it's an excellent choice for work areas where such wear and tear are common.
The conductor core of the URD wire is composed of aluminum alloy strands, compressed to 1350-H19. It is insulated with cross-linked polyethylene, and the conductors are then surface printed for easy identification. This comprehensive construction ensures the wire's durability and performance in various applications.
URD wire is a specific type of building wire intended for underground, residential use.
URD wire stands for “Underground Residential Distribution wire”.
URD wire is most often used as directly buried or installed in ducts for 600 volt secondary distribution.

The URD wire features a construction that comprises a concentric stranded or compressed aluminum conductor of the 1350-H19 grade. This conductor is insulated with cross-linked polyethylene, which provides superior protection. The insulated conductors are then surface printed for easy identification, and the neutral conductors are distinctly marked with triple yellow stripes. Additionally, black neutrals can be specified based on individual preferences or requirements.
Quadruplex Aluminum URD Cable
To make this wire, 3-phase conductors are assembled together with one neutral conductor. This cable can withstand temperatures of up to 90°C.
Triplex Aluminum URD Cable
This wire’s conductors are made using an aluminum alloy that has 99.5% aluminum and 0.5% silicon, copper, zinc and other such elements. These added elements make the alloy stronger.
Duplex Aluminum URD Cable
This wire is used in underground applications, especially those that use ducts and conduits. It is protected by polyethylene making it an ideal wire for many underground residential wiring. This polyethylene coat makes it possible for the wire to operate in environments whose temperatures can rise as high as 75°C.
URD Wire – Single Conductor Aluminum Cable
This wire is designed to be used in the wiring system of residential areas. These include detached & semi detached houses, row housing and town housing.
