Safety sliding wire support

1. Anticorrosive treatment should be applied

2. Continuous welding is required

3. Firmly installed, with consistent installation hole positions

Distance between safety sliding wire brackets

Single line "H" type ≤ 1.5M below 300A, ≤ 3M above 400A

Multi line seamless sliding contact line type 1.0-1.5M, conduit type 1.0-1.5M, cable pulley type 1.0-2.0M, and arc segment support spacing should be<1.0M based on site conditions

Safety sliding wire suspension

The position is correct, the installation is firm, and the quantity meets the requirements

Safety sliding line main body

1. Gap between protective shell and conductor ≤ 2mm

2. Straightness: allowable deviation from the height of the track center ＜ ± 15mm

3. Straightness: longitudinal tolerance with track center ＜ ± 15mm

4. Twist degree: ＜ 15mm/10m

Telescopic device

1. The quantity meets the regulations

2. The gap distance should meet the theoretical expansion caused by the maximum temperature difference at the installation site

Collector

1. The square steel frame is firmly welded, with a vertical tolerance of ± 3mm between the centerline and the sliding contact line

2. The size of the square steel bracket and the sliding contact wire should ensure that the collector arm is parallel to the main body of the sliding contact wire, with a tolerance of ± 3mm

3. The collector and sliding contact wire slide smoothly and meet the specified pressure (See the contact pressure gauge between the collector brush and the guide rail on the next page)

Fasteners

The torque for tightening the nut should comply with the manufacturer's recommended values. Recommended values: M10-28NM, M8-12NM, M6-6.5NM

Power incoming line

The incoming end is firm and cannot withstand tension
