Collection: ALUMINUM URD DIRECT BURIAL SINGLE, DUPLEX, TRIPLEX, QUADRUPLEX

Aluminum URD cables are specifically designed for secondary power distribution in outdoor and underground applications. These cables provide reliable and stable electrical supply to residential, commercial, and industrial properties. Whether you need a single conductor or a quadruplex setup, understanding the differences between each type of cable will help you select the right option for your needs.

Why Choose Aluminum for URD Cables?

Aluminum is widely used for URD cables because of its unique properties, making it an ideal material for underground and outdoor power distribution:

High Electrical Conductivity: Aluminum provides reliable power distribution, even at larger diameters, ensuring efficient electrical performance.
Cost-Effective: Aluminum is significantly less expensive than copper, making it the economical choice for large-scale projects.
Durability and Corrosion Resistance: Aluminum forms a natural oxide layer that protects it from rust, ensuring longevity in outdoor installations.
Flexibility and Ease of Installation: Its flexibility allows aluminum cables to be easily maneuvered during installation, even in tight spaces or duct systems.
Stable Performance: Aluminum maintains strong electrical conductivity even in cold climates, making it reliable in diverse environmental conditions.

Key Features of Aluminum URD Cables:

Temperature Rating: 90°C for wet and dry locations.
Durability: Resistant to oil, heat, ozone, chemicals, tears, and abrasion.
Approval: Accepted by RUS (Rural Utilities Service) for reliable usage.
Direct Burial: Suitable for direct burial without the need for additional conduit.

Types of Aluminum URD Direct Burial Cables

There are four main types of Aluminum URD cables—each designed for different applications based on the number of conductors and the electrical load they handle. Below is a breakdown of each type.

Single Conductor URD Cable
- Technical Use: Designed for underground distribution in duct or direct burial installations, handling single-phase loads in secondary circuits.
- Typical Use Cases: Commonly used in industrial power distribution, agricultural settings, and irrigation systems where single-phase power is required.
Duplex Conductor URD Cable
- Technical Use: Used for secondary distribution of single-phase power from transformers to residential service heads.
- Typical Use Cases: Perfect for service drops in residential areas, delivering power from pole-mounted transformers to homes.
Triplex Conductor URD Cable
- Technical Use: Used for secondary distribution of split-phase or three-phase power in residential and light commercial applications.
- Typical Use Cases: Commonly used for multi-unit dwellings or light commercial buildings that require three-phase or split-phase power.
Quadruplex Conductor URD Cable
- Technical Use: Ideal for secondary overhead or underground distribution of three-phase power for larger commercial or residential applications.
- Typical Use Cases: Best suited for large residential complexes, commercial buildings, or industrial sites that need three-phase service.

Why Aluminum URD Cables are Ideal for Direct Burial Applications:

Aluminum URD cables are specifically built to withstand the demanding conditions of underground installations. Their cross-linked polyethylene (XLP) insulation ensures durability in wet, dry, and corrosive environments. These cables provide exceptional flexibility for navigating curves in ducts and are cost-effective due to their low maintenance needs.

How do I choose between Single, Duplex, Triplex, and Quadruplex URD cables?

Choosing the right type of Aluminum URD cable depends on the specific requirements of your project:

Single Conductor URD is ideal for simple, single-phase underground power distribution, often used in industrial or agricultural settings.
Duplex Conductor URD is commonly used for residential service drops from pole-mounted transformers, delivering power to homes.
Triplex Conductor URD is suitable for multi-phase or split-phase power distribution in larger residential or light commercial applications.
Quadruplex Conductor URD is best for large commercial or multi-unit residential properties requiring three-phase power distribution.

What are the key factors to consider when installing Aluminum URD cables?

When installing Aluminum URD cables, consider the following factors:

Load Requirements: Ensure the cable type (single, duplex, triplex, or quadruplex) matches the electrical load of your application.
Installation Environment: Determine whether the installation will be in a wet or dry location, as these cables are rated for both.
Bend Radius: Aluminum URD cables are flexible, but understanding the minimum bend radius during installation is essential to avoid damage.
Local Regulations: Verify that the cable meets local electrical codes and regulations, such as being approved for direct burial or overhead use.

What maintenance considerations are there for Aluminum URD cables?

Aluminum URD cables are designed to require minimal maintenance, thanks to their corrosion resistance and durable insulation. However, regular inspections are recommended to ensure:

No physical damage: Check for any cuts, abrasions, or wear on the insulation due to environmental factors.
Stable connections: Ensure that all electrical connections are tight and secure, as loose connections can lead to power loss or overheating.
Proper grounding: Verify that grounding is intact and functional to ensure safe operation.

By following these maintenance practices, you can extend the lifespan of your Aluminum URD cables and avoid potential electrical issues.
