Burial cable is suited for wet, dry, and humid situations and is made to tolerate direct exposure to soil and moisture. It is intended to be buried underground in a trench. A solid thermoplastic sheath surrounds each individual electrical conducting wire inside the cable, keeping moisture out and safeguarding the wires from harm. Direct burial wires are used in a variety of applications, such as fiber optics, irrigation, cathodic protection, pet fencing, phone and other telecommunication cables, running electricity, and tracer wire installations for underground utilities.
