Contact line system for power supply of e.g. electric train, has carrying rope diagonally connected with contact wire from top to bottom by Z-rope that exhibits round cross-section, where Z-rope and contact wire are made of same material

摘要

#CMT# #/CMT# The system has a contact wire (3) connected with a carrying rope (1) by dropper cables, where the carrying rope is diagonally connected with the contact wire from top to bottom by a Z-rope (9), and the system runs along a rail. The Z-rope exhibits a round cross-section that comprises notches (27). The Z-rope and the contact wire are made of same wire material i.e. copper magnesium alloy, where the contact wire is connected with the Z-rope over a shock clamp (15). Outer ends of the contact wire and the carrying rope are connected with a retightening device. #CMT# : #/CMT# An independent claim is also included for a method for connecting a contact wire with a carrying rope within a contact line system for power supply of an electrical traction vehicle. #CMT#USE : #/CMT# Contact line system for power supply of an electrical traction vehicle e.g. electric train and trolley bus. #CMT#ADVANTAGE : #/CMT# The Z-rope and the contact wire are made of the same wire material i.e. copper magnesium alloy, thus ensuring high stability and/or tensile strength in the system. The system is mounted and maintained in a simple manner. The Z-rope exhibits the round cross-section, thus producing the Z-rope in a simple manner while reducing damage of arc surface area of the Z-rope. The utilization of the shock clamp enables reducing the weight of the system, thus improving driving dynamic properties of the system even in high speed traffic in railways. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of a contact line system. 1 : Carrying rope 3 : Contact wire 9 : Z-rope 15 : Shock clamp 27 : Notches.
