Sliding contact line is used to supply power to moving equipment. The quality of the sliding contact line is related to its service life and also affects the normal operation of the crane. Therefore, when selecting a sliding contact line, 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 insulation of the conductor, and also provides sun protection, moisture resistance, rain and snow protection, and dust prevention. 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 humans, 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 a sliding contact line, 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 may pass off sliding contact lines with lower current as those with higher current.
3. Quality and source of the aluminum alloy conductor material. This factor is also a major determinant of the price of the sliding contact line. 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 only way to stand firmly in the entire market for a long time.
5. Regarding the selection of the current collector for the sliding contact line, as a key component for crane power supply, how to select the current collector is particularly important. The current collector mainly consists of shoe pieces, shoe box, spring, collector bracket, collector support parts, etc. When selecting a current collector, first consider the manufacturer that matches the sliding contact line. Do not use the current collector indiscriminately, otherwise it will affect the normal operation of the crane, and in severe cases, it may burn out the sliding contact line.
How to choose a sliding contact line
1. Look at the structural form, such as safe combined sliding contact line or separated safe sliding contact line, rigid-based separated sliding contact line, 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 slide wire. A slide wire with a larger maximum current is generally better.
3. When selecting, look at its length, consider the total impedance of the slide wire or the material of the slide wire, and make a comprehensive consideration.
