4-4-4-4 Tulsa Aluminum XLPE URD Quadruplex Direct Burial Cable
What is 4-4-4-4 Tulsa Aluminum XLPE URD Quadruplex Direct Burial Cable？
4-4-4-4 Tulsa Aluminum XLPE URD Quadruplex Direct Burial Cable is an underground electrical cable that is also used as a service entrance cable and for wiring underground secondary circuits. This cable has four gauge conductors 4 AWG. Three of these conductors correspond to the phases of a three-phase system, and the fourth driver, that has yellow stripes, acts as the neutral conductor. It is a medium duty cable, with a temperature rating of 90°C and a voltage rating of 600 volts.

URD Cable Applications
4-4-4-4 Tulsa Cable URD has a rated current capacity that depends on several factors, including ambient temperature, installation and specific conditions of use. However, los 4-4-4-4 Tulsa usually have a fairly high current capacity due to their thickness and design.
The current capacity of a cable is determined taking into account the maximum allowable temperature of the conductor, heat dissipation capacity, and other safety factors. In general, This capacity is specified in tables provided by cable manufacturers or electrical engineering regulations..
