Question one: Which of the several types of trolley wires can be used on 75-ton vehicles?
The selection of the 75-ton traffic skid line mainly depends on the specific circumstances. If it is under normal conditions, the TGH-500A or TGH-630A trolley line can be used. If the environment is poor, consider using a steel body contact wire.
Question 2: Is there a national standard or industry standard for the trolley trolley line?
This is certainly true, and generally refers to the standard GB50055-2011.
Question 3: What kind of failure rate is lower than multi-stage and single-stage trolley lines?
For multi-level and single-stage trolley lines, if the two types of trolley lines are compared, the latter should be the same, that is, the failure rate of the single-level trolley lines is even lower.
