Problems solved by technology

The cable is easy to be pulled and twisted during the erection process. If the cable is too hard, it is easy to cause inconvenient erection and easy to break. At the same time, it is easy to be corroded by oil and chemical reagents when used in a harsh environment, resulting in the damage of the cable. Limited service life
In particular, for cables used for transmission in some special occasions, special measures need to be taken to make them anti-corrosion and acid-alkali resistant. The current practice is to install some necessary protective sleeves so that they can meet the corresponding anti-corrosion and acid-alkali resistance requirements. increased cost of use

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an acid and alkali-resistant fireproof cable and a preparation method thereof. Background technique [0002] Cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission cables across rivers and seas. The cable is easy to be pulled and twisted during the erection process. If the cable is too hard, it is easy to cause inconvenient erection and easy to break. At the same time, it is easy to be corroded by oil and chemical reagents when used in a harsh environment, resulting in the damage of the cable. Limited useful life. In particular, for cables used for transmission in some special occasions, special measures need to be taken to make them anti-corrosion and acid-alkali resistant. The current practice is to install some necessary protective sleeves so that they can...
