Overview
GJYMX Compact insulated bus ducts support three-phase three-wire, three-phase four-wire, and three-phase five-wire AC systems with frequencies of 50-60Hz and voltages up to 400V. Their rated operating currents range from 400 to 6300A. They serve as modern power supply and distribution equipment primarily for industrial plants, enterprises, institutions, and high-rise buildings. Bus ducts with plug-in connectors can conveniently branch power circuits through plug-in junction boxes or plug-in switch boxes. They offer advantages such as compact size, tight structure, high current-carrying capacity, and easy maintenance. Bus ducts can be installed directly from transformers to low-voltage distribution panels, or from low-voltage panels directly to distribution systems as feeder lines.
