Shenzhen Cable Trench Price _ Factory Customization _ Manufacturer _ Supplier [Dongguan Songshulin Environmental Protection Building Materials Co., Ltd.] Cable trench (cable trench) is an underground pipeline used for laying and replacing power or telecommunication cable facilities, and also serves as the protective structure for the laid cable facilities. 1. Cable trench is mainly used for burying cables to protect them from mechanical damage, chemical corrosion, sun exposure, rain, and other natural factors, and it facilitates the replacement or addition of cables as needed. 2. Structural Forms Cable trench comes in various pipeline structures such as rectangular, circular, and arch shapes. The layout of cable trenches in power plants and substation sites is usually related to the on-site equipment and topographical conditions. 3. Features Trench with a cover: It is necessary to uncover the cover for cable laying and maintenance, which is cumbersome, but civil construction is simple and cost-effective, thus widely used in substation and small to medium-sized power plants. Serving as a patrol path: Outdoor power distribution equipment areas usually have patrol roads for staff to inspect electrical equipment. Many stations use the cable trench cover as part of the patrol and operation path. Cable brackets: Cable brackets are installed inside the cable trench, typically made of metal materials, and are fixed to the trench wall by welding or screws to support the cables and maintain a certain distance from the bottom of the trench. Fire prevention measures: Cables in the cable trench usually take fire prevention measures such as applying fire-resistant coatings and sealing. Blocking walls: Blocking walls are set up at the entrance of cable trenches into buildings (such as control rooms and switch rooms) to prevent the spread of flames and smoke indoors in case of a fire and to prevent small animals from entering.
