Plugging Device


Plug In Unit


Ultra High Strength
The shell of this series bus bar is made of one piece of steel plate (Ma Steel), which greatly improves the load capacity and can guarantee a load of 60kg in the center of bus bar at a span of 6m, and the center position of the plate shell is not shifted by more than 10mm when the non-uniform temperature changes.

Extremely safe and reliable
Adopting separated air insulation type, the safety clear distance and creepage distance between phases are much larger than the standard requirements.
Internal insulation parts are made of high-strength engineering plastic, which improves the resistance of busway to movement and thermal stability.
The special construction used for the joints prevents misuse of the installation.
Safety protection baffle is set at the socket, only when the protection baffle is pulled open, the plug box can be inserted. When the socket is not in use at ordinary times, the protective baffle can be pulled closed and sealed with lead to prevent the entry of dust or foreign objects at the socket, and to prevent misuse, so that the safety performance of the bus bar is greatly improved.
There is no need to disconnect the power when plugging in the box, because the ground wire is always connected and disconnected first.

Flexible wiring
The busway jacks are modular in design, with a large number of jacks reserved for the entire system. This ensures that loads can be connected to the busway units in a short path and that no changes to the busway system are required for the addition or movement of shop equipment or shop refurbishment.

This series of busways is designed with seven current levels and uses only three levels of enclosures so that there is no need to change enclosures when the system varies capacity by adjacent current levels.

Extremely easy to install
The use of coupling with automatic compensation and single bolt clamping terminal with strong adjustability makes busway channel appear very convenient and flexible in the installation process, which greatly saves installation time.
