Description

Technical Field

[0001] This utility model belongs to the field of cable protection technology, specifically relating to a protective device for underground communication cables. Background Technology

[0002] A cable is an insulated conductor consisting of one or more mutually insulated conductive cores enclosed in a sealed sheath. It differs from ordinary wires primarily in its larger size and more complex structure. Cables are used to transmit and distribute electrical energy or transmit electrical signals, and typically consist of a conductor, insulation, and a protective layer. Communication cables are a general term for cables that transmit telephone, telegram, fax, television and radio programs, data, and other electrical signals. They usually consist of two main parts: the cable core and the sheath. The cable core is made up of multiple mutually insulated conductors twisted together, carrying the information transmission; while the sheath acts like a sturdy "armor," designed to protect the cable core from moisture, external mechanical damage, and electrical interference. Compared to overhead power lines, communication cables have advantages such as larger communication capacity, higher transmission stability, better confidentiality, and less susceptibility to natural conditions and external interference.

[0003] Currently available underground communication cable protection devices on the market are not fully functional when used by users. They require splicing and laying according to the length of the cable, which affects the user's use of the protection device and makes it inconvenient for users to perform internal maintenance.
