High-temperature resistant watertight cable and production method thereof

Abstract

The invention discloses a high-temperature resistant watertight cable. The center of the cable is a conductor formed by twisting seven nickel-plated round copper wires, the positions outside the conductors and between the conductors are filled with high-temperature resistant water blocking sealant I, a polytetrafluoroethylene insulation layer is extruded outside the high-temperature resistant water blocking sealant, a nickel-plated round copper wire shielding layer is woven outside the polytetrafluoroethylene insulation layer, high-temperature resistant water blocking sealant II are applied tothe surface of the nickel-plated round copper wire shielding layer, and a polytetrafluoroethylene sheath layer is extruded outside the nickel-plated round copper wire shielding layer. The present invention also provides a production method of the cable. The cable obtained by the invention not only has good high temperature resistance and watertight performance but also has excellent electrical performance, durable mechanical protection, small size, light weight and high flexibility.

Description

technical field [0001] The invention relates to a high-temperature-resistant watertight cable and a production method, belonging to the field of electric wires and cables. Background technique [0002] The "vessel" of the missile weapon refers to the cable on the missile, which is responsible for the transmission of various information of the missile. There are many sophisticated devices inside the missile, and they need to be highly coordinated with each other to ensure that the missile flies and hits the target according to the predetermined procedure. The signal interaction between these devices is complex and requires a reliable cable network to connect. Usually, a missile consists of fifty or sixty cables. Simple cables have dozens of signal nodes, and slightly more complex cables have hundreds or even hundreds. an information exchange point. If the cable fails, it will affect the function of the missile at the slightest, and lead to the failure of the flight test at ...
