INSULATING ANTI-PRESSURE TUBE BODY FOR SUBMARINE OPTICAL FIBER CABLE DEVICE, SUBMARINE OPTICAL FIBER CABLE DEVICE AND MANUFACTURING METHOD THEREOF

摘要

An insulation pressure-resistance cylinder body of submarine cable equipment, submarine cable equipment, and a manufacturing method are provided. The insulation pressure-resistance cylinder body includes: an installation cylinder, an insulation layer, and a pressure-resistance cylinder sequentially disposed from inside to outside, where a first groove is opened on an outer surface of the installation cylinder, and a second groove interlaced with the first groove is opened on an inner surface of the pressure-resistance cylinder, and the insulation layer is closely adhered to the outer surface of the installation cylinder and the inner surface of the pressure-resistance cylinder. Through the interlaced grooves on the outer surface of the installation cylinder and on the inner surface of the pressure-resistance cylinder, the insulation layer, the installation cylinder, and the pressure-resistance cylinder are closely and integrally combined, thereby improving stability of the cylinder body.
