Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a new type of Teflon cable with high temperature resistance. Background Technique

[0002] Teflon wire, commonly known as fluoroplastic wire, also known as high-temperature wire, refers to a wire whose insulating layer is made of fluoroplastic, and has the special property of high temperature resistance. Teflon is another name for polytetrafluoroethylene. Products made of this material are generally collectively referred to as "non-stick coatings"; it is an artificial synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material has the characteristics of being resistant to acids and alkalis and various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristic of high temperature resistance, and its friction coefficient is extremely low, so it can be used for lubrication purposes and has also become an ideal coating for the inner layer of non-stick pans and water pipes. The existing Teflon cables have poor high-temperature performance, resulting in low service life. Content of the Utility Model

An outer protective layer is arranged on the outside of the protective sleeve. Reinforcing layers are arranged on both the inner side and the outer side of the protective sleeve. A protective layer is arranged on the surface of the outer protective layer. The protective layer includes a fireproof layer, a high-temperature resistant layer and a wear-resistant layer. The high-temperature resistant layer is arranged on one side of the fireproof layer, and the wear-resistant layer is arranged on one side of the high-temperature resistant layer.

[0005] Preferably, a buffer medium is filled between the cable core and the protective sleeve, and the material of the buffer medium is foam rubber.

By designing the high-temperature resistant layer 72, the high-temperature resistance performance of the cable can be improved.
