Direct Burial
Direct burial involves placing cables directly into the ground. This method offers advantages such as simple construction and low costs. However, because directly buried cables are susceptible to damage from external forces and the soil environment, protective measures-such as the use of cable trenches or conduits-are required.
Cable Trench Installation
Cable trench installation involves laying cables within a trench, which facilitates maintenance and inspection. Supports can be installed inside the trench to arrange cables in layers, thereby improving space utilization. Nevertheless, constructing cable trenches entails higher costs, and necessary precautions-such as waterproofing and fireproofing-must be implemented.
Cable Tray Installation
Cable tray installation involves placing cables on trays; this method is suitable for indoor or outdoor settings where a large number of cables are present. Cable trays are easy to install and offer good heat dissipation, though they come at a relatively higher cost.
