Special optical hybrid cable for multifunctional digital city main battle fire engine

Abstract

The present invention relates to a special optical hybrid cable for a multifunctional digital city main battle fire engine. The optical hybrid cable includes a G657 bend-resistant optical fiber. A low-smoke halogen-free tight sleeve layer sheaths outside the G657 bend-resistant optical fiber. A first metal braided layer sheaths outside the low-smoke halogen-free tight sleeve layer. A low-smoke halogen-free insulating layer sheaths outside the first metal braided layer. A second metal braided layer sheaths outside the low-smoke halogen-free insulating layer. A thermoplastic polyurethane elastic outer jacket sheaths outside the second metal braided layer. The optical hybrid cable at least has the following advantages that the G657 bend-resistant optical fiber is adopted and the low-smoke halogen-free tight sleeve layer is disposed, so that the product has good bending performance; the first metal braided layer is a positive electrode, and the second metal braided layer is a negative electrode, so that the optical hybrid cable has good mechanical performance, saves effective space of the cable, and prevents an overlarge outer diameter of the cable; and due to adoption of the medical thermoplastic polyurethane elastic outer jacket, the optical hybrid cable has good biocompatibility.

Description

technical field [0001] The invention belongs to the technical field of communication cables, and in particular relates to a multi-functional digitalized photoelectric hybrid cable specially used for urban main battle fire trucks. Background technique [0002] With the gradual deepening of the development of the Internet in urban society, the digitalization requirements of fire trucks are becoming increasingly strong; as a social public welfare undertaking, it is imperative to upgrade and improve the digitalization of firefighting equipment. Therefore, firefighters and the command center need to grasp the information of the fire scene in real time, and carry out scientific and reasonable rescue and fire fighting work. Based on the above reasons, there is an urgent need to develop a special photoelectric hybrid cable for digital fire trucks. On the one hand, it can ensure real-time information communication on the fire scene; on the other hand, it can ensure the continuous pow...
