Support posts in electric fencing are vertical posts made of wood, metal, or plastic that hold and support electric wires or tapes at the correct height and tension. They ensure fence stability, maintain wire spacing, and prevent the wires from grounding by holding insulators.

An undergate cable is a heavy-duty insulated cable used in electric fencing systems to safely transmit high-voltage current beneath gates, driveways, or other non-electrified gaps** in a fence line.

The "100kg" typically refers to the tensile strength or durability rating of the cable's outer insulation/sheathing, meaning it can withstand physical stress or pressure up to 100 kilograms — useful in areas with vehicle or livestock traffic.
