• Ambient humidity:0% to 100%.

The busway joint utilizes a 4piece active compression sealing system.When the torque-limited shear bolts in the bridge-type joint are  tightened to the specified value (causing the bolt heads to snap off),the indicator label will detach.Following the cover tightening procedure, the seal cover is then compressed and secured onto the busway.The solid silicone gaskets at the joint and under the cover fully fill and seal all gaps,ensuring reliable IP68-rated waterproof integrity at the joint.

Cast lP68 Busway with Tap-off Unit (Plug-in Box)

Product features:the product has obtained the first 3C certification in China and reached the protection level IP68

Technical parameter

Fire-rated busway systems are primarily used in fire protection power distribution  circuits,generator backup power supplies,and fire-prone electrical applications to ensure emergency power sources maintain operation during fire events.
