Safety slide wire use scope maintenance

There are many ways to install the trolley wires. Different customers have different installation methods according to their own needs. Here, Shanghai Tianyi Company will briefly introduce several ways to install the trolley wires. I hope everyone will install the trolley wires. Avoid unnecessary mistakes in the process.

1) How to install the bracket?

In general, the brackets should be installed perpendicular to the rails, and all brackets should be level with the rails. The distance between installations is 2m. In order to ensure the overall line of the trolley line, the vertical error of the bracket installation must not exceed 1 cm, and the lateral error should not exceed 2 cm.

2) Installation The installation of the trolley line is divided into three types: upper slide, lower slide and side slide. The upper slide is generally used. The fitting bracket for the trolley wire is generally 1.5-2 meters. In special cases, it can also take measures to strengthen the distance. The distance between the three trolley wires is 400 mm. If the trolley wire is low-impedance, the distance between the wires can be increased. To 450mm.

3) Install insulating material assembly Fix the insulating material assembly on the reserved gap hole of the bracket to ensure that the insulator is straight.

4) Connect the slide wire to fix the two ends of the slide wire with a special fixing plate for connection. Tighten the screws to ensure that the slide wire joint is flat. The length of the slide wire connecting splint is 18~22cm, and the joint gap is 3-5 (mm). ).

5) Installation of temperature compensation device In order to prevent the expansion of the contact wire structure caused by temperature changes, the temperature control device is generally designed for the trolley wire. Shanghai Tianhao Company will diversify production according to the customer's design requirements. During installation, the temperature compensation device is directly fixed between the trolley wires. In order to ensure that the trolley wire expands and contracts under the condition of temperature changes, the expansion gap is adjusted in accordance with the on-site temperature.

6) Inspection and isolation device The inspection and isolation device is made of epoxy tree insulation board. The installation position is in accordance with the manufacturer's requirements. The installation method is the same as the connection of the trolley wire. After the connection is completed, the slide wire connector and the bakelite can be flattened.

7) Auxiliary cable fixing clips Auxiliary cable fixing clips should generally be installed on the inside of the trolley cable.

8) Power Supply Terminal Installation The power supply terminal should be installed at the connection of the rigid body slick line. The intermediate power supply, two-terminal power supply or three power supply modes are normally used.

If the user tries to install the slide contact or the side slide, please ensure that you must install it under the guidance of a professional installer. Do not attempt to install it casually to avoid unnecessary damage to the trolley wire. Shanghai Tianyi Company can also install professional technical personnel on-site service according to the requirements of customers.
