Conductor: It is a spring supported type that can be pushed in only at the lower part of the sliding contact line, but it must be synchronized with the traction device and ensure that the tension spring force is appropriate to avoid increasing the wear of the electric brush. The traction device is synchronized with the conductor and can be fixed to mobile electrical appliances such as cranes using bolts or welding methods, while ensuring that the conductor operates without torque.

7、 Selection instructions

When selecting this sliding line device, users should consider the total capacity and working system of the electrical equipment on the same span sliding contact line. The current carrying curve chart above is for users' reference. When selecting conductors, the capacity of the electrical equipment should be considered to match the conductor. When the single pole capacity of the conductor is insufficient, a bipolar conductor can be used.

8、 Installation Form Diagram
Note: This device generally adopts the front and side installation methods. Multiple arrangements and bends are allowed (with a minimum bend radius of 1.5m). The dimensions in parentheses are suitable for guide rails ranging from 200-300A, with a spacing of 90mm between L1L2L3PE.

9、 Power supply mode
When considering the safety of the sliding contact line power supply point, the total number and capacity of electrical equipment across the same sliding contact line, the task work schedule, the voltage drop value of the entire line length, and the environment should also be taken into account (voltage drop calculation can be based on the data in the previous guide rail parameter table). There are generally several types of power supply for users to refer to: ① Single ended power supply; ② Central power supply; ③ Two end power supply; ④ Power supply at 1/6 of both ends; ⑤ Power supply at both ends and three points in the middle.

10、 Installation and maintenance instructions
1Installation Instructions
Before installing the sliding contact wire, first fix the angle steel bracket according to the installation form selected by the user, and fix it according to the suspension spacing of the sliding contact wire. At the installation site, put the required suspension seat and one joint sheath on each end of the sliding contact wire every 6 meters, and also install an aluminum joint on one end. When installing the aluminum joint, it should be noted that only half of the aluminum guide rail can be inserted into the joint for the connection of the other guide rail. After the above work is ready, hang the sliding contact wires one by one on the bracket for full line connection. When connecting, tighten the screws of each joint. When the total length of the sliding contact line exceeds 200 meters, an expansion device should be installed (the expansion device is supplied by our factory at any time). When connecting the power line into the line, it can be connected at the joint every 6 meters. The specific connection method can refer to the previous joint device diagram.
When installing the curved sliding contact line, the suspension distance should be shortened accordingly, and the specific size can be determined according to the site conditions.
When installing the conductor, first install it on the matching square tube, choose the appropriate position to match the sliding contact wire and fix it on the electrical equipment. It should be noted that in order to ensure good tracking performance and contact ability between the conductor and the sliding contact wire, they should be installed in the same vertical and horizontal direction.

2. Maintenance and upkeep
The safety sliding contact line should be regularly inspected during normal operation, as electrical equipment is the main production tool of every industrial and mining enterprise, and even a slight error can directly affect the production efficiency of the factory. When checking the sliding contact wire, it is necessary to check whether there is any looseness or detachment at the joint every 6 meters. When checking the conductor, it is necessary to check whether the moving parts rotate flexibly, whether the tension spring is fatigued, and whether the electric brush is worn (these situations can affect the conductivity of the sliding contact wire and the tracking performance of the conductor. Adjustments should be made in a timely manner).
During the holiday equipment maintenance period, remove the conductor from the conduit and check the wear of the conductor brush roller. If the extension of the brush is less than the specified effective length, it should be replaced in a timely manner. If the guide roller is severely deformed, it should also be replaced to maintain the normal operation of the conductor and good contact with the brush, and to investigate the cause. Among all the components of the safety sliding contact line, the electric brush is a normal part that will wear out.

For environments with severe corrosive gases, it is necessary to inspect the corrosion of brackets, suspension clamps, and tractors; And take timely measures to apply rust proof materials.
The location where the sliding contact line is used, such as during infrastructure construction. Do not impact or press the transmission conduit, and do not place heavy objects on the transmission conduit. Prevent deformation and cracking of transmission conduits, which may affect their use and lead to safety accidents. After the completion of infrastructure construction, the construction waste on the transmission conduit should be immediately cleared.
During normal maintenance, staff are not allowed to step on the transmission conduit or its support to prevent damage to the flatness of the entire line and accidents.
