The single-pole security trolley line has the same features as the multi-polar trolley line. There are also great differences. This article briefly describes the differences between the two. The single-pole safety trolley line and the multi-polar trolley line belong to the electrical A product. There is a certain difference between the two in application. This article briefly introduces this.
The difference is as follows: The cross-sectional area of ​​a single-pole safety conductor line conductor is large, and the amount of current that it carries is also large, which is much larger than that of multi-pole. The magnitude of the load current is also determined. The single-pole trolley wire is suitable for a large power crane workshop, and the multi-pole trolley wire is also used in a small power workshop.
The difference two: the use of different conductor materials, unipolar slip conductors of aluminum alloy conductors, multi-polar conductor of the copper conductor, the two conductors are different, it determines the resistance of the two are different, of course, the conductivity of the two The loss is relatively small.
Difference 3: The applicable environment is also different. According to my understanding, the unipolar trolley line is suitable for most occasions. The multipolar trolley line is mainly used in power plants, steam workshops and other occasions. It is not as wide as the unipolar trolley line.
Difference four: the structure is different, the single-pole conductor line conductor is a conductor, and the multi-pole conductor line is composed of three, four, six, and more copper bars, and the accessories of the two are also different.
