Abstract
A polyethersulfone temperature-resistant wet insulated cable for supercritical power generation relates to the technical field of cable production, in particular to the technical field of special cable production. A wrapping tape, an inner sheath and an outer sheath are arranged outside wire cores from inside to outside in sequence. The cable is characterized in that the wire cores are formed by tinned anaerobic copper wires and polyethersulfone composite insulating layers; the wrapping tape is an aluminium-plastic composite tape; the inner sheath is made of polyethylene; and the outer sheath is made of polyethersulfone composites. The cable has the characteristics of good aging resistance, high temperature resistance, high humidity resistance, good working stability under special environment and long service life and can conform to the requirements for high temperature, high humidity, more grease dirt, strong interference and the like at the supercritical power generation occasions.
Description
Technical field
The present invention relates to the production technical field of cable production technical field, particularly private cable.
Background technology
Normal cable is provided with twining package tape, inner sheath and oversheath successively outside core, general material ageing resistace is relatively poor, and useful life is short, and the stability of working under or the environment that humidity is bigger higher in temperature is poorer, the cable that therefore, must exploitation can adapt to special occasions.
Summary of the invention
The object of the invention is to provide a kind of and has the good supercritical generating of high temperature resistant, high humidity, anti-interference with the wet cable of polyether sulfone insulation heatproof.
The present invention sets gradually twining package tape, inner sheath and oversheath from inside to outside outside core, be characterized in: described core is made up of zinc-plated copper free wire and polyether sulfone composite material insulating barrier, described twining package tape is an aluminium-plastic tape, described inner sheath is a polyethylene, and described oversheath is the polyether sulfone composite material.
The present invention has that ageing resistace is good, high temperature resistant, the characteristics of anti-high humidity, good operating stability under particular surroundings, the characteristics of long service life, requirement such as temperature height, high humidity, the greasy dirt that can adapt to the supercritical generating occasion is many, interference is big.
In order further to improve the moisture resistance properties of product, the present invention also is provided with waterstop between twining package tape and inner sheath.
In addition, core of the present invention is generally seven groups.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention is provided with seven groups of cores, and every group of core is made up of zinc-plated copper free wire 1 and polyether sulfone composite material insulating barrier 2, and polyether sulfone composite material insulating barrier 2 is arranged on outside the zinc-plated copper free wire 1.
Outside seven groups of cores, set gradually twining package tape 3, waterstop 4, polyethylene inner sheath 5 and the polyether sulfone composite material oversheath 6 made with aluminium-plastic tape from inside to outside.
Claims (3)
