Budapest – exchange of trolleybus switches
Technical Data, Description:
Exchanging of 5 sets electric trolleybus switches (underun type) for the tension type, including the modification of the related overhead contact line in one crossing and one trolleybus loop. Part of the project was the elaboration of project documentation with the aim of increasing the speed of the trolleybus through the switches.
The original switches were coil type with a 20° pitch. EZ Praha exchange these switches with eletrical (motor) switched in tensile design, with an angle of 10°. The anchor points from switches were adapted to the existing masts, only one new mast was built.
The overhead contact line is simple, non-tensioned, with flexible hinges. A support net made of stainless ropes is hung on existing hinges on houses and masts. The delivery included 4 sets of 10 ° electric switches, 1 set of 20 ° ES, one set of 20 ° mechanical switch and 2 trolleybus crossings with blowing el. arc using magnets. The total length of the new contact wire Cu 100 mm2 was 2 370 m.
