DEVICE FOR INTERCONNECTING CONTACT WIRES OF SUSPENDED SWITCH OF CONTACT SYSTEM Russian patent published in 1995 - IPC

FIELD: railway roads. SUBSTANCE: the switch has rope branches and members for fastening with contact wires. The contact wires are secured to the cross-like lining mounted on the outer contact wire by way of clamps. To exclude power transfer and friction between the wires, the top contact wire is insulated under the cross-like lining by dielectric [ shaped bushing-slide having longitudinal split from downward. The ends of straight part of the bushing are bent upward, rotated by 90°, and interconnected with a fastening bolt above the lining with a spaced relation to it The space is at least 5 mm to permit contact wires to be longitudinally heat displaced. The top wires moves in bushing. The bushing moves along the cross lining. EFFECT: enhanced reliability. 3 dwg
