The invention discloses a multilayer armored cable maintenance connector box and an installation method thereof. The multilayer armored cable maintenance connector box comprises bending reinforcers, connection seats, clamps, tail clamps, screws, a shell and a cable connector, wherein the connection seats, the bending reinforcers, the camps and the tail clamps are symmetrically arranged at two end parts of the shell; the connection seats are fixedly connected with the bending reinforcers respectively; the connection seats at two ends are connected and fixed through the screws; armored steel wires are pressed between the connection seats at two end parts through the internal clamps and the tail clamps; a wrapping-type cable connector for being connected with a cable is also arranged in the shell; and the cable connector comprises a connecting pipe, shielding adhesive tapes, insulating adhesive tapes, a copper shielding net, a waterproof adhesive tape, a stress adhesive tape and a constant spring. The multilayer armored cable maintenance connector box can adapt to recovery of armor structures of multilayer armored submarine cables; rapid maintenance of the submarine cables can be easily achieved by a simple locking mode; and compared with a traditional connector box, the connector box disclosed by the invention is higher in manufacturing speed, wider in applicability and faster in installation.
Description
technical field [0001] The invention relates to a maintenance joint box suitable for emergency repair of multi-layer or single-layer armored submarine cables, and restoring the armor protection and electrical performance of the submarine cables. Background technique [0002] With the increasing demand for energy in my country, the development of offshore oil and gas and offshore wind power is also rapidly increasing. As an important medium for power transmission, submarine cables are of utmost importance to their safety and reliability during use. Fishing boats and other ships in the ocean are a regular threat to submarine cables, and anchoring is a relatively common form of damage. It can cause cables to fail to transmit power, break, and eventually lead to the paralysis of the entire power system, resulting in huge economic losses. , and the longer the offshore construction period, the higher the cost and the greater the risk. In view of this situation, a multi-functiona...
