Things You Need to Know about Busduct Systems

In order to transfer power in an efficient and effective manner without disrupting the equipment, a busduct is a component of the electrical system that serves as a connection between two or more pieces of electrical equipment. The design of this electrical equipment takes current and voltage requirements, as well as short circuit requirements, space availability, and aesthetic considerations into account.

There are three main categories used to classify air-insulated busducts: isolated phase busduct, segregated phase busduct, and non-segregated phase busduct. In summary, isolated phase busducts are commonly employed in large power facilities to connect generators to transformers and other equipment. Compared to other types of busducts, each phase conductor is housed in its own enclosure, allowing it to sustain a higher current for a given busduct.

In Segregated Phase Busducts (SPBD), which are essentially metal-enclosed systems, all phase conductors are housed in a common enclosure but are partitioned by barriers. These barriers come in two different materials: metal and insulated. Non-magnetic barriers possess the capacity to substantially reduce the stresses imposed during phase-to-phase defects.

The three phase conductors are united together in a single metal enclosure in a non-segregated phase busduct, also referred to as an NSPBD, and there are no phase barriers separating adjacent phases. Various varieties of NSPBDs are available, with the most prevalent being the traditional type and the interleaved type.

The conventional way of doing things up until a few years ago was to use cables to transmit power from one piece of equipment to another. In any event, this method proved to be quite effective provided that the required power was comparatively low.

Conversely, within a constantly evolving context, the dimensions and capacities of numerous items of equipment have substantially expanded. Cable was not a feasible option for transmitting such substantial quantities of power due to the inherent limitations and disadvantages it entails. Due to the lack of power transmission and distribution, other solutions must be considered, which in turn will lead to the development of more modern transportation methods, such as busducts. Ultimately, it facilitated the resolution of numerous problems resulting from the use of cables.

It is possible that you may inquire about the parameters pertinent to selecting the busduct. The voltage rating, BIL value, continuous current capacity, short-circuit current rating, ambient temperature, temperature rise limitations, and busbar material are among the essential parameters evaluated during the initial selection of busduct.

The parameters outlined above are, of course, the most fundamental; however, the design of the busduct is also affected by a broad range of other factors. In this regard, you should make it your personal responsibility to conduct further research and acquire additional knowledge regarding the busduct.
