Key Considerations in The Use Of Dense Bus Duct

 

With the increasing requirements for power distribution efficiency in modern industrial and commercial buildings, dense bus duct has become an important choice in the field of power transmission due to its high current carrying capacity, compact structure and easy installation. However, in actual applications, ignoring key considerations may lead to performance degradation or even safety hazards. The following are the core considerations in the use of dense bus duct.

 

​​1. Environmental adaptability selection​​
The performance of dense bus duct is significantly affected by environmental factors. High humidity, corrosive gases or extreme temperature environments may accelerate the aging of insulation materials or cause short circuit risks. Therefore, in special scenarios such as chemical industry and offshore platforms, bus duct products with moisture-proof and corrosion-resistant coatings should be preferred, and ensure that the installation area is well ventilated.

 

​​2. Installation specifications and support spacing​​
During the installation process, the support spacing requirements provided by the manufacturer must be strictly followed. Excessive spacing may cause the bus duct to deform due to its own weight or thermal expansion, which in turn affects the stability of electrical contact. At the same time, special tools are required to fix the joints to avoid mechanical stress concentration and damage to the insulation layer.

 

​​3. Regular maintenance and inspection​​
Although the design life of dense bus duct is long, problems such as loose joints and aging of insulation layers may still occur after long-term operation. It is recommended to conduct infrared thermal imaging inspection every six months, focusing on checking local overheating areas; comprehensively check the tightness of joints at least once a year, and clean up dust to prevent creepage risks.

 

​​4. Current carrying capacity matching and expansion planning​​
When selecting, the expected load current must be accurately calculated, and at least 20% capacity redundancy must be reserved. If capacity expansion is required in the future, the temperature rise margin of the existing bus duct system should be evaluated first to avoid blindly increasing the load and causing overload risks.

 

​​5. Fire prevention and emergency measures​​
In scenarios such as high-rise buildings or tunnels, it is necessary to ensure that the bus duct is equipped with standard fireproof sealing materials when passing through fire partitions. In addition, it is recommended to set temperature sensors at key nodes and link the fire protection system to achieve early warning.

 

Correct use and maintenance of dense bus ducts can not only extend the life of the equipment, but also ensure the safe and stable operation of the power system. With the advancement of technology, the integration of intelligent monitoring functions in the future will further reduce the difficulty of operation and maintenance, but basic specifications are still irreplaceable.
