250-250-250-3/0 Rust Aluminum XLPE URD Quadruplex Direct Burial Cable
What is 250-250-250-3/0 Rust Aluminum XLPE URD Quadruplex Direct Burial Cable？
250-250-250-3/0 Rust 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 250MCM gauge conductors. 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.
Also know as: 250-250-250-3/0 XLPE oxidized aluminum urd cable, 250-250-250-3/0 XLPE oxidized urd direct burial cable, 250-250-250-3/0 XLPE oxide quadruplex cable, 250-250-250-3/ 0 XLPE oxide quadruplex wire, 250-250-250-3/0 XLPE four conductor oxide wire, 250-250-250-3/0 XLPE four conductor oxide cable, 250-250-250-3/0 XLPE oxide direct burial electrical cable, 250- Rust Direct Burial Power Cable 250-250-3/0 XLPE, oxide aluminum direct burial cable 250-250-3/0 XLPE.

URD Cable Applications
250-250-250-3/0 Rust Cable URD has a rated current capacity that depends on several factors, including ambient temperature, installation and specific conditions of use. However, los 250-250-250-3/0 Rust have a fairly high current capacity due to its 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..
