Air insulated bus duct
Scope Of Application
High-Rise Building
Air-type bus duct is suitable for the power supply of high-rise buildings. Due to its characteristics of miniaturization, high efficiency and energy saving, it can meet the power needs of high-rise buildings.
Large Factory
For the power supply of large factories, traditional cables and busbars are often difficult to meet the demand. At this time, air-type bus trunking can be used for power transmission to reduce transmission costs.
Losses And Safety Risks
Other Places
Air bus duct is also suitable for other places where power transmission is required, such as airports, overhead passages, etc.
Summarize
Air bus duct is a new type of power transmission equipment. It has the advantages of safety, reliability, high efficiency and energy saving. It has a wide range of applications in the power supply of high-rise buildings, large factories and other places.
Extremely Safe And Reliable
A. Using separated air insulation type, the safe clearance distance and creepage distance between phases are much larger than the standard requirements.
B. The internal insulation parts are made of high-strength epoxy resin, which improves the vibration resistance and thermal stability of the bus duct.
Bus ducts of all current levels use unified cover plates, which have a high degree of standardization, strong interchangeability, and convenient variable capacity interfaces.
