Darui Electric recommends

   

(1) Power supply duct: carries the current from the power source to the current collector. Each duct is 4M long, and can also be customized according to customer requirements. Specifications refer to Table 3-1

    (2) Current collector: slides in contact with the guide rail inside the duct to conduct current, and provides current to other mobile electrical equipment (see Figure 5-1).

    (3) Middle inlet box: device for introducing power current from the middle of the duct (Figure 5-2)

    (4) End inlet box: device for introducing power current from the top end of the duct (Figure 5-3)

    (5) Connecting clamp: located at the joint of two adjacent ducts, used for connection, fixing and insulation (Figure 5-4)

    (6) Shaping clamp: keeps the duct from deforming (Figures 5-5, 5-6

    (7) Fork: transmits moving thrust or pull to the current collector, and moderately absorbs transmission errors and shocks. The fork can be matched according to the number and model of current collectors (Figure 5-7)

    (8) Outdoor safety busbar trench structure

Multi-pole busbar installation scheme, precautions for product selection

(1) Power supply method

    When the voltage drop exceeds the standard, in addition to selecting a larger cross-section duct, different power supply methods can be used to change the calculated length L.

(2) Determination of thermal expansion compensation

    1. Indoor installation: For total length within 100m, generally no thermal expansion compensation point is added. During assembly, a gap of 5mm should be left at the duct joints.

    2. Outdoor installation: For lines exceeding 100m, thermal expansion compensation points should be considered.

    (1) Multi-pole busbar installation scheme, gap compensation method:

    Principle: Gaps are staggered between adjacent ducts at the duct connections to allow for thermal expansion compensation. Both ends of the compensation point should be fixedly suspended, and the rest floatingly suspended. The compensation gaps for each duct section are as follows:
