What is used to protect direct burial cable from moisture and chemical injury?

Direct burial cable is designed to be installed underground where it can be directly exposed to soil moisture and potentially harmful chemicals. To ensure the longevity and functionality of the cable, protective measures are essential. Sheathes are specifically engineered to cover and protect the cable from these environmental hazards.

The sheath functions as a barrier against moisture ingress, which can lead to corrosion and deterioration of the cable's internal components. Additionally, it provides some protection against chemical exposure from the surrounding soil, which can vary depending on the location and type of terrain. This added layer of protection helps maintain the integrity of the electrical connections and ensures safety in operation.

While insulation tape, protective sleeves, and conduits are used in various applications to offer some level of protection, they are not specifically designed for the purpose of protecting direct burial cables in the way sheathes are. Insulation tape primarily serves to secure and insulate electrical connections, protective sleeves may offer some additional physical protection but are not typically used for direct burial applications, and conduits are used for routing wiring above ground or through walls but don't serve the same purpose for directly buried cables. Thus, the choice of sheathes is appropriate in this context.
