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 [0001] The invention relates to the technical field of cable production, in particular to the technical field of production of special cables. Background technique [0002] Conventional cables are provided with wrapping tape, inner sheath and outer sheath in sequence outside the wire core. Common materials have poor aging resistance, short service life, and more stable work in environments with high temperature or high humidity. Poor, therefore, it is necessary to develop cables suitable for special occasions. Contents of the invention [0003] The purpose of the present invention is to provide a polyethersulfone insulated temperature and humidity resistant cable for supercritical power generation with high temperature resistance, high humidity and good anti-interference performance. [0004] In the present invention, a wrapping tape, an inner sheath and an outer sheath are sequentially arranged outside the wire core from the inside to the outside, and the...
