Closed Busway ChuteNo Chinese content provided.

Closed busbar applications are typically found in low-voltage, high-current power supply and distribution systems, usually installed within electrical shafts, and they supply power to each floor using a single central busbar system. A closed busbar system can be composed of various busbar units.

　　（1Linear Busbar Unit

The linear busbar unit is designed for extending power supply and distribution lines, and is used in conjunction with a tap-off busbar and a connector box for the distribution of electrical loads.

　　（2Start-end Busbar Unit

The initial busbar unit is paired with the initial incoming line box to form the connection components for busbars and cables. The initial busbar unit can also be connected to transformers or distribution panels.

　　（3Expansion Bus Unit

Expansion busbar units are designed to absorb the axial displacement of busbars caused by thermal expansion, when the length of the busbar exceeds...80mOne expansion bus unit should be installed at this time.

　　（4Reducer Bushing Unit

The transition busbar unit is designed for connecting different rated current units within the same system, ensuring a more economical and rational power supply for the entire busbar system.

　　（5Various Bus Bar Bending Units

　　（6Busbar Terminal Box

Busbar terminal boxes are used at the termination ends of enclosed busbars to ensure the power supply safety of the busbar system.

　　（7Socket box

The junction box is used to derive power outlets from enclosed busbars, and it is equipped with an automatic air switch for cutting off and connecting the power supply.
