Low-Tension Bus Duct (L.T. Bus Duct) or Sandwich Bus Duct is a system used for electrical power distribution in low-voltage applications. It serves as a reliable and efficient means to transfer electrical power from one location to another, often within the same facility. The term “sandwich” refers to the layered construction of the bus duct.
The primary components are conductors that carry electrical current. These conductors are typically made of aluminum or copper, depending on the application and specific requirements.
Insulation
Sandwich Bus Ducts feature layers of insulating materials, such as epoxy resin-impregnated paper or other dielectric materials, separating the conductors to prevent short circuits.
Enclosure
The bus duct is enclosed in a protective housing, usually made of metal or other robust materials, to ensure safety and protection against environmental factors.
Supports and Connections
Bus ducts are designed with appropriate supports and connections to facilitate easy installation and maintenance.
Application
01
Industrial Facilities
L.T. Bus Ducts are widely used in industrial environments where there is a need for efficient and flexible power distribution. They are commonly employed in factories, refineries, and other manufacturing facilities.
02
Commercial Buildings
Large commercial buildings, such as shopping malls and office complexes, may use Sandwich Bus Ducts for distributing power to various sections of the building.
03
Power Plants
Bus ducts are integral components in power plants, providing a reliable means to transfer power between different sections of the facility.
Rating
Voltage Rating
L.T. Bus Ducts are designed for low-voltage applications, typically with voltage ratings of 415V or 800V.
Current Rating
The current-carrying capacity of the bus duct depends on the design and materials used. Ratings can range from hundreds of amperes to several thousand amperes, depending on the application.
Advantages
Flexibility
L.T. Bus Ducts offer flexibility in designing and configuring power distribution systems. They can be easily adapted to changes in the layout or load requirements.
Efficiency
Bus ducts provide a low-impedance path for current flow, minimizing energy losses and ensuring efficient power transmission.
Space-Saving
Compared to traditional cable systems, bus ducts are often more compact, saving valuable space in electrical installations.
Ease of Installation
The modular design and ease of connection make installation and maintenance relatively straightforward.
