Direct buried metallic armour is designed to provide mechanical protection when the cable is installed directly in the ground, and it can be configured with either a single layer of armor or two layers (dual armor) depending on the installation’s protection needs. A single armor layer offers basic protection, while adding a second armor layer increases resistance to crushing, abrasion, and potential intrusion in harsher soils or deeper bury conditions. Triple armor isn’t a standard option for direct burial armor in typical practice, so the suitable configurations are single or dual.
