During my walk today, I noticed these small parallel connected lines. What purpose do they serve?

  • \$\begingroup\$ They may be a type of anti-resonance bar similar to the Stockbridge damper. \$\endgroup\$

  • \$\begingroup\$ Dampers are calibrated weights. These appear to be crimped on jumpers. \$\endgroup\$

Not certain, but:

Cable joins in a long run of cable.
The strength join is not adequately electrically conductive and the ',jumpers' provide lower resistance joins.


These are most probably points installed from where, in future, power cables can be attached to supply to nearby consumers.
