Isolated enclosed bus duct/isolated phase busway

1.Self-cooled isolated enclosed bus duct

Self-cooled isolated enclosed bus duct

Self-cooled isolated enclosed bus duct is used as the transmission circuit connection between the generator outgoing line and main transformer, auxiliary transformer, excitation transformer to transmit the electricity safely. This product conforms to the IEEE C37.23, GB/T 8349 and other standards at home and abroad.

Product Features

1.Totally-enclosedstructure to basically eliminate the heating of the steel nearby the bus duct.

2.Completely isolated three phase to decrease the earth fault and avoid the inter phase short circuit.

3. The isolation between the bus duct and connecting device to prevent accident diffusion effectively.

4.The enclosure protection class can reach IP65 to prevent the human body and outside particles from approaching the electrified body to ensure the personal safety and reliable operation of equipment. 

Forced air cooled isolated phase bus duct

Used for connecting the main circuit between the outlet of the 50MW~1000MW generating set and the main transformer and the current transmission of the branch circuit of the factory.

Current level 1000A~30000A, voltage level 10.5kV~35kV.

The whole housing grounding point strengthens the shielding effect on the circulation of conductor housing to eliminate the steel heating near the busway.

Supporting micro positive pressure hot air circulation maintenance system ensures that the internal insulation performance of busway is not influenced by the external environment to improving stability.

It can be used to improve the safety of busway system operation by supporting the conductor temperature on line monitoring system, the hydrogen leakage monitoring device and the local discharge monitoring device.
