Overview

The excellent protection capability of air type bus duct is mainly composed of shell, conductor, insulation support and connecting components. Conductors are usually made of copper or aluminum materials and fixed inside the casing through insulating brackets. A certain gap is left between the conductors of each phase and between the opposite casings, and air is used as a natural insulating medium to fill it. When current flows through a conductor, the heat generated is dissipated through air flow and the casing, thereby maintaining normal operating temperature.

Product Details

Excellent protection capability of air type bus ductIt mainly consists of an outer shell, conductors, insulation supports, and connecting components. Conductors are usually made of copper or aluminum materials and fixed inside the casing through insulating brackets. A certain gap is left between the conductors of each phase and between the opposite casings, and air is used as a natural insulating medium to fill it. When current flows through a conductor, the heat generated is dissipated through air flow and the casing, thereby maintaining normal operating temperature.

Working principle of air type bus duct:

The working principle of air type bus duct is based on its structural design. The conductive busbar is responsible for transmitting current, while the metal casing not only provides mechanical protection, but also serves as a grounding path to ensure system safety. The existence of air gaps enables effective heat dissipation of bus ducts when transmitting high currents, avoiding safety hazards caused by overheating. In addition, air serves as an insulating medium, avoiding the aging problems that may arise from the use of solid insulation materials and extending the service life of bus ducts.

Advantages and characteristics of air type bus duct:

1. High conductivity:

Using high-quality conductor materials with low resistance and high conductivity can effectively reduce line losses.

2. Safe and reliable:

Adopting an insulated support structure to prevent direct contact between wires and ground or other metal materials, reducing the risk of electrical leakage.

3. Good heat dissipation performance:

The air type bus duct has a large internal space, which can provide good heat dissipation conditions and avoid accidents caused by overheating.

4. Flexible and adjustable:

The length of the air type bus duct can be adjusted according to actual needs for easy wiring and installation.

Excellent protection capability of air type bus ductPrecautions for selection and use:

Although air type bus ducts have many advantages, the following points should still be noted when selecting and using them: first, ensure good handling of their joints to avoid poor contact caused by oxidation; Secondly, due to its relatively high cost, cost-effectiveness needs to be comprehensively considered in small and medium-sized buildings; Finally, considering the special nature of its installation and transportation process, a dedicated person is needed to be responsible for maintenance and upkeep.

In summary, air type bus ducts play an important role in modern power transmission and distribution due to their unique advantages and wide application scenarios. With the continuous advancement of technology and the growth of market demand, it is believed that it will play a more critical role in the future power system.

Comparison with densely insulated bus ducts:

The dense insulated bus duct adopts solid insulation materials (such as polyester film or epoxy resin) to wrap the conductor, with a compact structure and high insulation strength. In contrast, air type bus ducts rely on air insulation, have a relatively simple structure, and have lower costs. However, in humid or dusty environments, air type bus ducts may be affected by the environment and have slightly inferior insulation performance compared to dense insulation types. However, in dry and well ventilated places, air type bus ducts can work stably and are easy to maintain.

Comparison with fire-resistant busbar trunking:

Fire resistant busbar trunking is designed for applications with high fire safety requirements and can maintain power transmission for a certain period of time at high temperatures. Air type bus ducts usually do not have specialized fire-resistant design, so their fire resistance performance is relatively weak. But for ordinary building environments, air type bus ducts can already meet daily needs, with low cost and easy installation.

Convenience of installation and maintenance:

The convenience of installation and maintainability in the later stage of busbar trunking are also practical factors that need to be considered in the selection process. This includes:

-Connection method: Modular design and convenient insertion of bus ducts can greatly improve installation efficiency and reduce on-site workload. --Flexibility: Whether the system is easy to expand andChange? When it is necessary to increase or move loads, the plug interface design and expansion capacity of the bus duct are particularly important.

-Maintenance requirement: Is it convenient to inspect, clean, and repair? Is the shell easy to open? Is the joint location easy to inspect and tighten? All of these will affect the maintenance costs and workload throughout the entire lifecycle.

-Installation space: The cross-sectional dimensions, length, and required installation space of the bus duct need to match the actual situation on site.
