So, you’ve heard of Duplex and Quadruplex cables, but do you know the differences between them? Quadruplex aluminum underground wire has two distinct designs. Duplex is the most common type of cable. Duplex is often used in the home for its convenience, but there are also advantages to Quadruplex as well. Keep reading to learn more about these types of underground wire. And don’t forget to check out our article on Duplex cable.
Listed below are some characteristics of Duplex and Quadruplex cable. Each one has its own unique characteristics. Duplex cables have one lead with thermocouple connectors and one with Camlock or Dinse connectors. Duplex cable is a common choice for temporary or outdoor service and is available in Duplex, Triplex, or Quadx construction. Duplex cables can accommodate both low-voltage and three-phase power.
A duct-mount transformer can either use a duplex or quadruplex cable. The latter is used to connect two power lines. A duct-mounted transformer is able to distribute power at lower voltages, making it suitable for secondary distribution. Duplex and Quadruplex aluminum cable can be installed directly in ducts or pre-pulled into a duct. For secondary distribution, this type is one of the best choices.
Aluminum URD Triplex and Quadruplex cable has two to three individual conductors laid parallel to one another. They are available in either two or three phase configurations and one neutral. They are made from premium aluminum alloy 1350-H19 that meets the requirements of the American Society for Testing and Materials .
Triplex and Quadruplex aluminum cables are both designed for secondary distribution. Secondary distribution occurs after a transformer reduces the voltage to a safe level. Both Quadruplex and Triplex cable can be installed in ducts and are insulated for additional protection. The URD version can function in wet environments. Here are the advantages of each type. Here are some examples. Quadruplex cable is more flexible, can be used in ducts and is insulated to withstand water and is also available in a wet location.
Quadruplex cable is made of three phase conductors connected in parallel. Its neutrals are stranded and compressed. Cables marked with “YES” have sequential footage markers. In addition, the conductors are durably surface printed for easy identification. And it is suited for high-voltage, low-voltage and secondary distribution applications. Quadruplex cables are available in both silane and XLPE.
Aluminum URD quadruplex cable contains conductive components of 1350-H19, which is a premium alloy. It has a diameter of 9-10% lower than standard polyethylene. Its black polyethylene coat protects it from heat. Standard polyethylene is rated for 75degC, but cross-linked polyethylene is preferred for hot climates. Similarly, cross-linked polyethylene is more durable in a wide range of temperatures.
Aluminum quadruplex overhead service drop cable supplies three phase power. This type is typically connected to a pole mounted transformer and consumer weather head. It has a maximum conductor temperature of 75 degrees Celsius (phase to phase) and is characterized by a concentric strand aluminum conductor. The messenger conductor is bare. When used in a lighting fixture, it is insulated with XLP (cross-linked polyethylene).
Overhead aluminum Quadruplex service drop ABC cable is used for overhead services, outdoor lighting, and temporary construction. They are available with neutral bare and insulated conductors, and can be manufactured according to customer specifications. All products manufactured using this type of cable are designed to meet or exceed the applicable ASTM and ICEA standards. For outdoor lighting, it is rated up to 600 volts. ICEA S-79-474 also applies to quadruplex cable.
