Abstract

The invention provides a submarine cable bonding force detection method, and relates to the technical field of submarine cable detection. The submarine cable bonding force detection method comprises the following steps of selecting samples, testing bonding force and drawing a conclusion. A plurality of submarine cable samples are selected and the conditions of submarine cables in the sea are simulated. One submarine cable sample is divided into several sample sections, and the bonding force, including the bonding force between a steel wire armor and a copper layer, the bonding force between the copper layer and a PE insulating layer, and the bonding force of a steel tape armor and the PE insulating layer, of each sample section is tested separately. Finally, the test results are determined, and whether the test results are qualified is analyzed. The submarine cable bonding force detection method provided by the invention is used for ensuring that the submarine cables can withstand the pulling of external force without being damaged, and is of great significance for ensuring the normal and smooth operation of the submarine cables.

Description

technical field [0001] The invention relates to the technical field of submarine cable detection, in particular to a method for detecting the adhesive force of a submarine cable. Background technique [0002] Submarine cables are wires wrapped with insulating materials, laid on the seabed and underwater in rivers, and used for power or telecommunication transmission. Modern communication submarine cables use optical fiber as the signal transmission medium to transmit telephone and Internet signals. [0003] Submarine optical cables can generally be divided into stainless steel optical fiber unit, steel wire armor, copper conductor, PE insulation layer, steel tape armor and PE insulation layer from inside to outside. Due to the many structural layers of the submarine optical cable, in the submarine cable laying project, the drag and traction of the submarine cable often occur, resulting in dislocation or even separation between the above-mentioned structural layers. Therefor...
