2. Rigid trolley wire, which is a kind of conductive wire with copper as the reinforcing material and steel wire laid on the insulator. Generally, the copper material is inserted into the light rail according to the size of the current carrying capacity, or the grooved copper wire is clamped by a steel clamp, and then fixed on the insulator.
The current carrying capacity of the rigid trolley line and the conductor's load area are relatively large. The carrier area of ​​the conductor is generally 70~540mm2, the rated current is 300~1850A, the maximum temperature is 95C, and it has good resistance to touch and is in poor condition. Under the conditions of use, its performance will not be reduced, it can ensure a long life, and has a high degree of machine strength, will not be deformed and bent, it is not easy to break the line and so on.
3ã€Safety trolley wire, this type of trolley wire is made of special copper or aluminum material as the electrical conductor, installed in the shield made of PVC plastic, and the collector on the crane extends from the bottom into the shield with the conductor Slides, no conductive body exposed, so called safety line.
Talking about the Classification of Common Sliding Lines
1. Angle steel wire contact line, which is a kind of trolley wire type widely used in China for the past several decades. Its advantage is that it can save the consumption of non-ferrous metal and the structure is strong and wearable. Its disadvantages are large electric energy loss, difficult construction, and operation. When sparks are generated due to poor contact, especially for some large-tonnage cranes, the load current is large.
