Description

Technical Field

[0001] The utility model relates to the technical field of power cable protection devices, in particular to a plastic sleeve for cable protection. Background Art

[0002] Power cables are cables used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power station outgoing lines, internal power supplies for industrial and mining enterprises, and underwater transmission lines across rivers and seas. Power cables carry the lifeblood of our lives, and damage from external forces can severely impact our daily lives. Power cable protective conduits are mechanically strong tubing installed over the cable to protect it from damage. They are widely used in the power industry. Currently, commonly used power cable protective conduits are conventional circular plastic or metal tubes. Several or even dozens of them are typically laid together to form a bundle. Small-diameter conduits are typically assembled using pipe clamps or strapping tape, while large-diameter conduits are assembled using pipe pillows. Strapping tape can create clutter and an unsightly effect. Pipe clamps and pipe pillows also take up considerable space, leaving large gaps between the pipes. Large-diameter pipes, such as MPP power conduits, require concrete encapsulation when buried underground. The use of pipe pillows results in significant concrete waste and increased costs.
