How to choose a single-stage safety wire and multi-tube type wire

Sliding lines can be divided into two types: single pole safety trolley lines and multi-pole trolley lines. There are many similarities between them, and there are many great differences. In this company, the company introduced a simple introduction for our customers. Under these two types of trolley lines.

The single-pole safety trolley line and the multi-polar trolley line belong to the same 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 conductor, multi-pole 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 three: The application occasions are different. According to my understanding, the single-pole trolley wire is suitable for most occasions. The multi-pole trolley wire is mainly used in power plants, steam workshops and other occasions. It is not as wide as the single-pole trolley wire.

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.
