LINK STRING OF CONTACT SUSPENSION Russian patent published in 2022 - IPC B60M1/225 

FIELD: contact wires attaching methods.

SUBSTANCE: invention relates to a device for attaching contact wires to carrying cables. The link string of the contact suspension contains links conjugated with each other, the ends of which are made in the form of loops, while one of the links is made insulated to prevent the flow of current from the carrier cable into the contact wire. The lower link of the string, connected to the contact wire by means of a string clamp, is made of an electrically insulating material, the wear resistance of which is lower than that of the material of other string links. At the same time, the upper end of the lower link is made in the form of a loop, and the lower end is in the form of a polygon, the lower sides of which form an obtuse angle, preventing the inclination of the lower link in case of abrasion of its loop below the level of the working surface of the contact wire.

EFFECT: increasing the reliability of the operation of the link string and contact suspension as a whole.
