Sulfate is a compound composed of sulfate ion (SO42-) and other metal ions. It is an electrolyte, and most of it is soluble in water. Sulphate minerals are salts formed by the combination of metal elements (including ammonium) and sulfate. Because sulfur is a valency element, it can produce different minerals in different valence states in nature. When it combines the highest valence S6 + with four O 2 - to form SO42 -, and then with metal cations, it forms sulfate. In sulphate minerals, more than 20 metal cations are combined with sulfate. That is, sulfate containing sulfate is sulfate.

1. The installation space of the multi-level trolley line is smaller than the single-stage trolley line. Since the multi-polar trolley line is only installed in a single-line system, the copper strips of all grades are in one pipe, and the unipolar trolley line can be used. Three-phase four-wire installation method, if there is a failure, it is easy to repair to find the problem! And the attachments of the two are also different.
2. Unipolar safety trolley wire, the main structure is aluminum alloy conductor, shell is made of polyvinyl Chloride and special material. Aluminum alloy conductor wear stainless steel strip, its heat dissipation, safety, conductivity are the first choice for mobile devices, to find some of the formal trolley line manufacturers to buy, single-pole safety trolley line service life can be more than 10 years; The multi-pole wire structure is composed of PVC plus special materials and copper sheets. The interior of the multi-polar wire is hollow. The most commonly used is the four-pole wire. The working condition is that the carbon on the current collector The brush transmits current by friction with the copper plate. The difference in the conductors of the two also determines the difference in the resistance between the two. Of course, the conduction losses of both are relatively small.
3. Although the multi-pole trolley wire is mainly used in power plants, steam workshops and other occasions, it is still not as wide as the application range of single-pole trolley wires!
What is the classification and difference of safety trolley lines?
There are many kinds of trolley wires, including safe trolley wire, single-pole combined trolley wire, multi-tubular trolley wire, seamless trolley wire, steel trolley wire, and many buyers purchase. The conditions of the system itself and the characteristics of the trolley line are used to select the trolley line. When the single-pole trolley line is selected, multi-level trolley lines are taken into consideration. What is the difference between them?
