What is a direct buried cable?

Direct-burial cable is a type of cable designed to withstand direct exposure to the soil and moisture and is rated for wet, dry, and damp environments. It does not always need conduit, but it can be run inside the conduit to add additional protection to any electrical system.

Why choose direct buried solar cable?

Direct buried cables have key advantages over overhead lines, which are exposed for long periods of time and are susceptible to damage from natural conditions, especially in coastal areas where hurricanes and storms are a common risk. Direct burial cables have jacket insulation suitable for dry and wet environments.It is convenient for direct burial and protecting it from the elements outdoors.

But to a certain extent, direct burial is more susceptible to mechanical damage and chemical or electrochemical corrosion of the surrounding soil, as well as termites and rodents. Therefore, the direct buried cable needs to be able to withstand the same harsh environmental conditions as the outdoors. In addition, the direct buried cable needs to be able to withstand shocks, and once in the ground, the direct buried cable can be walked, built, driven over and hauled heavy equipment, the cable needs to be durable enough to withstand harsh conditions.
