Commonly Asked Questions about 4-4-4-4 Aluminum Tulsa URD Cable

General Information about the Aluminum Tulsa URD Cable

• 4-4-4-4 Aluminum Tulsa URD Cable is an underground power distribution cable which is engineered for use in secondary electrical transmission system. Which basically means it’s a service cable which wires current from a service drop cable. The 4-4-4-4 refers to four conductors, four phase, with an AWG size of 4.

Tulsa 4-4-4-4 Cable is commonly used for agricultural irrigation. It is made of four aluminum conductors; of which three are electrodes and one grounding conductor. Aluminum conductors are stranded along a concentric and compressed at as per 1350-H19. The aluminum conductors are insulated with XLPE (Cross Linked Polyethylene). XLPE insulation offers protection from abrasion and corrosive chemicals.

• Electrical cable insulation is very important because it ensures that the safety of the cable and the user is not compromised. The cross linked polyethylene insulation resin is a semi-semi conductor and will not subject the user to electric shocks. On the other hand, XLPE is corrosive resistant and thus protects the cable from corrosive chemicals. Tulsa 4-4-4-4 aluminum cable is intended to serve in harsh rocky conditions since it is installed underground. This cable is designed to transmit 85 amperes of current with a voltage rating of 600V.

• Tulsa 4-4-4-4 URD aluminum cable distributes power at an operating temperature of 90 degrees. On this post I share with you some of the frequently asked questions on 4-4-4-4 Tulsa aluminum URD Cable.

1. Are there similarities between Tulsa 4-4-4-4 Aluminum URD and 6/3 uf-b Copper Cable?

• Yes. Tulsa aluminum URD and 6/3 uf-b copper cables have similar features based on their construction, purpose and physical appearances. The two cables are designed for electrical transmission. They are made of stranded conductors; which means many wires are twisted on each other in rope lay. Stranding improves flexibility and electrical conductivity of the conductors.

• This enhances installation since the electricians will use less effort to twist and bend the cables. They both have grounding conductors which dislodges hazardous charges from that conductor which would otherwise cause shock. A ground conductor is also referred to as the neutral conductor. It discharges the charges to the ground, a process known as earthing.

• Grounding conductors are separately insulated from the other electrodes. This insulation creates a barrier between the ground conductors and the electrodes. The barrier basically ensures smooth electrical flow thereby eliminating power blows that would otherwise lead to fire outbreaks as a result of electrical faults. Imagine connecting a cable with live wires in direct contact with neutral conductors, it would be full of disasters with electrocutions and power blows all over.

• Electric cables are designed with different voltage ratings. As for Tulsa 4-4-4-4 aluminum and 6/3 uf-b cables, they are medium duty power cables meant to distribute voltage not exceeding 600 volts. Therefore, electricians should ensure that during installation they observe the voltage ratings for safety and efficiency of the distribution system. These cables are secondary transmission cables and are installed through underground power distribution channels.

2. Will 4-4-4-4 Tulsa URD distribute 70 amps at 170 feet without conduits?

• Tulsa 4-4-4-4 URD cable is designed to transmit up to 85 amperes in duct system. Therefore distributing 70 amperes won’t be a problem. However, it is important to always remember that the Tulsa aluminum cable is specifically made for installations through cable conduits and ducts. Ducts provide protection from abrasion and friction which are associated with all underground cable installations; this installation method creates a conducive environment for transmission of the highest amount of ampheres which is 85.
