sliding contact lines
are used to supply power to moving equipment. The quality of sliding contact lines is related to their service life and also affects the normal operation of cranes. Therefore, when selecting sliding contact lines, it is essential to pay attention to the quality provided by the manufacturer. Below, we will tell you how to distinguish the quality of sliding contact lines. Let's take a look together.


1. Thickness of the PVC shell. Generally, the shell of the sliding contact line serves to protect the conductor and provide insulation, as well as to protect against sun, moisture, rain, snow, and dust. The thickness of the shell is also a criterion for measuring the quality of the sliding contact line. If the shell is relatively thin, it may be accidentally damaged by human factors, and the safety performance will also be greatly reduced.


2. Cross-sectional area and thickness of the conductor. Obviously, the larger the cross-sectional area of the conductor, the better its heat dissipation; the thicker the conductor, the stronger its conductivity. When purchasing sliding contact lines, it is necessary to inspect the cross-sectional area of the conductor and also the thickness of the conductor. It is not ruled out that some manufacturers pass off sliding contact lines with lower current ratings as those with higher current ratings.


3. Quality and source of the aluminum alloy material for the conductor. This factor is also a major determinant of the price of sliding contact lines. Better aluminum alloy conductor material means a higher price, and vice versa.


4. Overall appearance design. This item may seem to have little effect, but it actually accounts for a certain proportion. The overall appearance design of the sliding contact line fits most engineering environments, and the design is conducive to protecting the sliding contact line, adding highlights from an aesthetic perspective. This will enhance the competitiveness of the product in the sliding contact line market. Doing a good job in the overall design of the sliding contact line and improving its quality is the way to sustain a long-term presence in the entire market.


5. Regarding the selection of the current collector for the sliding contact line, as a key component for crane power supply, how to choose the current collector is particularly important. The current collector mainly consists of shoe pieces, shoe boxes, springs, collector brackets, and collector support parts. When selecting a current collector, first consider a manufacturer that matches the sliding contact line. Do not use collectors indiscriminately, as this may affect the normal operation of the crane, and in severe cases, it may burn out the sliding contact line.


How to choose sliding contact lines


1. Look at the structural form, such as safe combined sliding contact lines or separated safe sliding contact lines, rigid-based separated sliding contact lines, etc.


2. When selecting, based on the total power of all cranes used, you can calculate the maximum current and use the magnitude of the current to determine the quality of the sliding line. Sliding lines with a larger maximum current are generally better.


3. When selecting, consider its length, and take into account the total impedance or the material of the sliding line. A comprehensive consideration is needed.
