Re-tensioning device for uniformly maintaining tension in overhead railway power cable, has cylindrical weight with at least two concrete parts that are assembled at non-horizontal contact surface transverse to that of adjacent weight body

摘要

The device has cylindrical weight bodies made of concrete stacked on a holder connected to the cable. At least one of the weight bodies consists of at least two concrete parts (2) that are assembled at non-horizontal contact surfaces. The contact surfaces of the parts of adjacent bodies are mutually transverse.
