Abstract: A modular array for a security fence system includes a tension module with a plurality of tension devices, a tensioning compensation module with a plurality of tensioning compensation devices, and a plurality of conductors each extending between a tension device and a tensioning compensation device. The modular arrays may be stacked for increased fence height. A conductor support module individually supports each conductor. An angular deviation module accommodates right, obtuse or acute angles. The tension devices automatically set the tension in the conductors to a predetermined tension. The tensioning compensation devices automatically accommodate expansion or contraction of the conductors due to temperature changes. All of the components of the modular array may be shipped in a standard pallet.
