b Keep away from severe vibration areas and try to avoid hot spots.
c pay attention to the convenience of maintenance.
(2) Select the suitable suspension method for the trolley wire. a. Select the appropriate type and size of the suspension bracket according to the site conditions;
b suspension spacing standard length 1200mm, the longest should not exceed 2000mm;
(3) Precautions for installation of the trolley contact line a. According to the installation diagram, determine the positions of the functional sections such as the power supply section and the expansion section, and number them according to the installation location.
b Install the first slide wire, which must be hung with a fixed hanger to serve as a baseline for alignment.
c When installing the first trolley wire (catheter), adjust the parallelism of the centerline of the running track of the equipment to be no more than 1.5mm/1000mm. The subsequent installation of the trolley wire ensures the straightness and power consumption of the first trolley wire. The straightness of the running track of the equipment is not more than 1.5mm/1000mm.
d For the DHGJ slip line, it must be effective to ensure good grounding performance for each slip line.
e After the installation is completed, the entire line should be rechecked. When the first installed sling (catheter) is not used as a benchmark, it is suspected to be replaced with a floating sling.
f Inspect the installation status of the entire line to ensure that the parallelism of the track of the entire line and the electrical equipment and the straightness of the slide wire (catheter) itself are not more than 15mm.
h The final commissioning of the electricity was conducted and it was found that the problem was solved immediately.
The correct installation of multi-pole tube type wire
(1) The determination of the installation position of the trolley wire is close to the transmission position and is installed on the same side of the electrical equipment.
