URD (Underground Residential Distribution) cable refers to a type of electrical cable designed for use in underground electrical distribution systems. DWC offers a variety of high-quality cables commonly used to supply electrical power to utilities including residential areas, as well as light-to-medium-duty commercial buildings. Our cables met all UL and Insulated Cable Engineers Association (ICEA) standards, carrying a voltage rating of 600v.
Our products consist of a concentric stranded or compacted aluminum conductor, made of 1350 series alloy. The phase conductors are combined with the neutral conductors to form a twisted cord. The URD cable is covered with cross-linked polyethylene (XLPE) insulation, which is black. The conductors are insulated and marked with yellow stripes, making it easy for technicians and installers to identify them.
URD cable is utilized by electric utilities, electrical contractors, and electrical engineers in work environments where a high level of resistance to abrasion and scratches is crucial. This type of wire can be installed in both moist and dry environments. It is capable of tolerating temperatures up to 90°C. The most common types of triplex and quadruplex URD feature insulation properties that offer exceptional durability, flexibility, and dependability.
Safe and Reliable:
URD cable is designed to be buried underground, making it ideal for use in areas where overhead power lines are not feasible or desirable. The cable is also protected from physical damage and environmental elements, making it a safe and reliable option for electrical distribution.
Durable and Resistant:
URD cable is made of high-quality materials that are resistant to moisture, heat, and other environmental factors. This makes it ideal for use in harsh conditions and helps to ensure its longevity and durability.
Easy to Install:
URD cable is designed to be easy to install, even in difficult or remote locations. The cable is often installed by trained professionals and can be buried quickly and efficiently.
Compared to overhead power lines, URD cable is a cost-effective solution for electrical distribution. The cable is also often cheaper than other types of underground power distribution systems, making it a good choice for many residential, commercial, and industrial applications.
By burying the electrical distribution system underground, URD cable helps to improve the aesthetics of a neighborhood or area. Overhead power lines can be unsightly and can reduce property values, but URD cable is hidden from view, making it a more visually appealing option.
Can URD cable be used in both residential and commercial applications?
Yes, URD cable can be used in both residential and commercial applications. The cable is designed to supply electrical power to homes, as well as commercial buildings, and is ideal for areas where overhead power lines are not feasible or desirable.
How does URD cable compare in terms of safety and reliability to overhead power lines?
URD cable is considered to be a safer and more reliable option for electrical distribution compared to overhead power lines. By burying the electrical distribution system underground, URD cable is protected from physical damage and environmental elements, making it a safe and reliable option for electrical distribution.
What is the lifespan of URD cable, and how often does it need to be replaced?
The lifespan of URD depends on a number of factors, including the quality of the cable and the conditions in which it is used. URD cable is made of high-quality materials that are resistant to moisture, heat, and other environmental factors, which helps to ensure its longevity. However, regular inspections should be performed to ensure that the cable is in good condition and free of defects.
Is URD cable more expensive than other types of underground electrical distribution systems? The cost of URD cable can vary depending on a number of factors, including the length of the cable and the materials used. However, compared to overhead power lines, URD cable is a cost-effective solution for electrical distribution. The cable is also often cheaper than other types of underground power distribution systems, making it a cost-effective choice for many residential, commercial, and industrial applications.
What is the voltage rating of URD Cable?
The URD cable has a voltage rating of 600v.
What Are Some URD Wire Specifications?
URD cable is constructed with a concentric stranded or compacted 1350-H19 aluminum conductor and covered with cross-linked polyethylene insulation. The insulated conductors have surface markings and are identified by neutral triple yellow stripes. Black neutral conductors can also be requested.
Are there variants of the URD cable?
Yes, these variants include the Quadruplex Aluminum URD Cable, the Triplex Aluminum URD Cable, the Duplex Aluminum URD Cable, and the URD Wire for Single Conductor Aluminum Cable.
Quadruplex Aluminum URD has a 600 volt rating and is designed to be used in secondary distribution circuits where you are installing in ducts or in a direct burial type of application. The maximum operating temperature is 90 degrees Celsius in both wet and dry conditions.
