Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 As shown, a light-duty waterproof frequency conversion marine cable according to the present invention includes a main core conductor 1, a first insulating layer 2 is arranged outside the main core conductor 1, and an extruded package is formed outside the first insulating layer 2 A first water-blocking semi-conductive shielding layer 3 is provided. The first insulating layer 2 and the first water-blocking semi-conductive shielding layer 3 are double-layered and co-extruded. The main line core conductor 1, the first insulating layer 2 and the first water-blocking semi-conductive shielding layer 3 form a main core unit, and there are three main core units, and a ground core unit is arranged tangentially outside the adjacent main core unit, and the ground core unit It includes a ground core conductor 4, a second insulating layer 5...

Abstract

The invention relates to a lightweight waterproof variable-frequency ship cable including a main wire core unit and a ground wire core unit. A waterproof filling layer is disposed outside the main wire core unit and the ground wire core unit, and is wrapped in a semi-conductive water-resistant belt. A light waterproof inner sheath is disposed outside the semi-conductive water-resistant belt. A metallic shield layer is arranged outside the light waterproof inner sheath, and a flame-retardant outer sheath is arranged outside the metallic shield layer. The lightweight waterproof variable-frequency ship cable is suitable for a variable-frequency power supply, small in size, and light in weight and has waterproof performance.

Description

technical field [0001] The invention relates to a cable, in particular to a marine cable. Background technique [0002] With the application of frequency conversion technology, cables suitable for frequency conversion power supply have also begun to be used. Marine frequency conversion cables not only require a symmetrical conductor structure, but also increase the shielding layer to prevent insulation breakdown caused by the accumulation of high-order harmonic voltage and anti-interference. At the same time, Because the cables are used on ships or oil platforms, they are easily exposed to moisture, so the cables need to be waterproof. The general water-blocking structure will cause the weight of the cable to be heavy, which will increase the load on the ship, so the structural design of the cable requires the characteristics of light weight and small size of the cable. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to overcom...
