The invention provides a high-pressure submarine cable and a cable composite explosion-proof box, which comprises a shell, a control box and a cable laying box, the shell is shaped like a cuboid; The control box and the cable laying box are inside the shell; an explosion-proof baffle is arranged between the control box and the cable laying box; the outer part of the shell is covered with a layer of explosion-proof layer; the outer part of the explosion-proof layer is provided with an anti-corrosion layer; the upper part of the shell is provided with a ventilation fan; the ventilation fan is connected with the interior of the shell through a ventilation pipe; a wheel frame is arranged in the cable laying box; a wheel is arranged on the wheel frame; the bottom part of the shell is also provided with a cable laying port; the output end of the cable on the wheel is connected with the cable laying port; the input end of the cable on the wheel is connected with a relay in the control box; the upper part of the relay is provided with an explosion-proof switch; and a gas concentration detector and a wheel switch are arranged in the control box. The high-pressure submarine cable and a cable composite explosion-proof box has the advantages that the safety of the environment inside the box is ensured by various explosion-proof and anti-corrosion means, and the cable is not damaged in the event of an accident.
Description
[0001] (1) Technical field [0002] The invention relates to an electrical device, in particular to a composite explosion-proof box for a high-voltage submarine cable and an optical cable. [0003] (2) Background technology [0004] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. The optical cable is mainly composed of optical fiber, plastic protective sleeve and plastic sheath. There is no metal such as gold, silver, copper and aluminum in the optical cable, and generally has no recycling value. An optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way, and is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. The optical cable needs to be ver...
