Dropouts: These are pre-manufactured openings in the bottom or side of the tray that allow cables to exit smoothly. The engineering composition of charging piles is generally divided into charging pile equipment, cable tray and optional functions DC charging piles are often equipped with components such as switches, AC contactors, charging guns, lightning protectors, fuses, electricity meters, DC contactors. Our most popular dropout options are the BDO, SDO and UDO. The BDO is 4” wide and has snap in mounting tabs that eliminate the need for attachment hardware. Ladder cable tray without covers provides for maximum air flow, dissipating heat produced in current carrying conductors. Dust buildup is minimal compared to other types of cable tray, such as ventilated trough or solid bottom.
