What is a safe sliding contact line, and what are the general specifications of safe sliding contact lines? - Yangzhou Darui
Darui Electric recommends for you
The quality of safe sliding contact lines can be measured according to the following standards:
1. Carbon brush service life -- it is a consumable item, and the travel distance affects the equipment maintenance cycle.
2. Quality of the sliding contact line shell -- applicable temperature, environment, etc.
3. Performance of the current collector -- mainly from the service life of the wheels, the design of the turning wheels, and whether the current collector can be used in various environments.
4. Expansion issue of the sliding contact line -- expansion needs to be considered when the length exceeds 100 meters.
5. Voltage drop issue -- the voltage drop varies according to the length of various copper bars.
General specifications of safe sliding contact lines:
First is the single-pole safe sliding contact line, second is the multi-pole safe sliding contact line, and third is the single-pole steel body sliding contact line. They are collectively referred to as safe sliding contact lines. Of course, there are also some special models of sliding contact lines, such as seamless sliding contact lines, etc.
The single-pole safe sliding contact line is suitable for the power supply system of most mobile equipment. Its simple material, easy installation, convenient maintenance and repair, and low price make it one of the first specifications and models of safe sliding contact lines considered by many customers. The single-pole sliding contact line is suitable for mobile equipment with currents between 150A and 2500A.
The multi-pole safe sliding contact line is made of copper bars. Its conductivity and energy-saving performance are significantly improved compared to the single-pole safe sliding contact line, but its cost also increases a lot. Moreover, due to the different structure, its current carrying capacity is much lower than that of the single-pole sliding contact line. It is generally used on small-power mobile equipment, with an operating current between 50A and 300A.
The steel body sliding contact line is mainly used in some special occasions, such as high temperature, high corrosion, and high humidity environments. It is suitable for operation in all occasions, but because of its high cost, it is mostly only selected in these special occasions.
