Cable migrating and moving in water

Abstract

The invention relates to a cable migrating and moving in water, which belongs to the technical field of electromechanical products. In order to meet the special requirements on wiring for an electrical installation working underwater, the invention provides a cable which cannot be enwound and wringed by self, cannot be daggled in a pool bottom and is basically parallel with the pool bottom surface when migrating and moving in water, and has an outer diameter not more than 15 millimeters. The cable comprises a conductor, an insulting layer, a cable core center padding, an inner protective layer and an outer protective layer. The cable is characterized in that the thickness of the inner protective layer made of foamed plastic is less than 3 millimeters, and the outer diameter of the cable is not more than 15 millimeters. The cable is used for connecting the electrical installation working underwater and supplying power for the same. The cable is soft with hardness, has elastic resilience and cannot be enwound and wringed by self when migrating and moving disorderly under water along with the electric installation, the inner protective layer is made of the foamed plastic so that the cable has light weight and the function of blocking water, is suitable for horizontal operations, cannot be daggled in the pool bottom and is basically parallel with the pool bottom surface in work, and has small outer diameter size, simple structure and low cost, and the manufacturing process and devices are general process and devices.

Description

technical field [0001] The invention relates to the technical field of electromechanical products, in particular to a cable that travels in disorder along with underwater electrical devices in water. Background technique [0002] There is a kind of electrical equipment that I want to export to European and American countries. The device generally moves in a disorderly manner on the bottom of the pool with a water depth of about 2 meters. It works horizontally and has special requirements for wiring. When moving, it cannot be twisted and twisted by itself. When moving, the wiring cannot be dragged on the bottom of the pool or the angle with the device is greater than 45 degrees, so that the resistance is too large, and the outer diameter of the wiring should not be greater than 15mm. The structure of the buoyancy cable whose application number / patent number is 200710133261 cannot meet the above-mentioned functional requirements. This technical solution is applied to deep-wate...
