Cable screen cross-bonding

On long high voltage single-core circuits, the cable screens are cut at joints and reconnected in rotation so that each screen runs alongside each phase for one third of the section. This cancels most of the induced sheath voltage and circulating current. Bonding diagrams show the screen connections crossing at each joint, with link boxes and sheath voltage limiters.

Drawing use: SLD / Schematic
Application: Connections & wiring
Reference family: IEC
Form evidence: Cross-bonded cable screen arrangement. Independent IEC-context illustration; not certified IEC geometry.

A distinction that matters

Cross-bonding transposes screens between phases; conductor interchange transposes the phase conductors themselves.

Cable straight-through joint

The straight-through joint connects two cable lengths end to end, restoring insulation, screen and sheath continuity. It is shown on cable route drawings and network diagrams at joint bay positions, because joints are the most common failure points on long underground circuits and their locations are needed for fault finding.

Drawing use: SLD / GA
Application: Connections & wiring
Reference family: IEC
Form evidence: Straight-through cable joint. Independent IEC-context illustration; not certified IEC geometry.

A distinction that matters

A straight-through joint links two lengths of the same cable; a branch joint takes off a second cable.
