What is the gap between angle steel wire and safety wireline?

October 26, 2022

What is the difference between Angle Steel wire and safety wireline?
Although the angle wire has the same purpose as the safety wire, the safety and reliability of the two are obviously different. The angle wire is used as a traditional drag method. The conductor is directly exposed to the air. Therefore, it is easy to rust, oxidize, accumulate ash, accumulate oil, etc., and directly affect its electrical conductivity, and may even cause accidents.
Although the running deviations of the slide rails of the angle rails are not required to be high, they are more sensitive to the “bounce” caused by the large orbital joints of overhead cranes, and the power-off phenomenon often occurs. The material of bare steel Angle Iron is large, and the occupied space is large. The slip line has low conductivity, large line loss, and many failures.
The safety trolley wire is different. The outer casing and the supporting part of the power transmission device are made of special engineering plastics. The insulation and corrosion resistance are good and they have a certain strength. Moreover, its wire body is located in the guide rail, which can not only conduct electricity but also serve as a guide rail, which can ensure that the brush pressure is not affected by the impact of the trolley's movement or vibration.
The safety wire does not cause arcs when the guide rails come into contact with the brush surface. The safety performance is high and it is installed on the same side of the driver. It is not only convenient for operation but also for safety considerations. In addition, the softness and high temperature resistance of the safety trolley line are better, and it is an indispensable part of the power supply for overhead cranes.
Although the price of a seemingly safe trolley line is relatively high, its failure rate is extremely low, so the overall cost-effectiveness is quite high. The safety trolley line can be used not only in cranes with poor indoor environment, gas corrosion, dust, high temperature, and humidity, but also because it has no bare sliding lines and is not affected by rain, snow, and frost weather.
