Low-cost ultra-large capacitance high-reliability thermocouple compensation cable

Abstract

The invention relates to the technical field of cables, in particular to a low-cost, super-capacitance, high-reliability and high-temperature-resistant thermocouple compensation cable that can be used for a new type of armed helicopter engine. It includes an inner core group, the inner core group includes a positive electrode cable and a negative electrode cable, the inner core group is wrapped in a total shielding layer, the outer side of the total shielding layer is wrapped with a protective layer, and the positive electrode cable includes a first silica fiber The first silica fiber bundle is wrapped with a nickel-chromium metal layer, and the nickel-chromium metal layer is wrapped with a first composite high-temperature-resistant insulation layer, and the negative electrode cable includes a second silica fiber bundle. The silica fiber bundle is wrapped with a nickel-silicon metal layer, and the nickel-silicon metal layer is wrapped with a second composite high-temperature-resistant insulating layer. The invention solves the contradiction that the supercapacitance of the cable, the high temperature resistance, the electric strength and the total outer diameter of the cable are mutually restricted and cannot be realized simultaneously.

Description

technical field The invention relates to the technical field of cables, in particular to a low-cost ultra-large capacitance, high reliability, and high-temperature-resistant thermocouple compensation cable that can be used for a new type of armed helicopter engine. Background technique Although my country has made considerable progress in the research and development of military armed helicopters in recent years, the WZ 10 and WZ 19 have all been publicly displayed at air shows, and the army and aviation units have begun to assemble. However, the core component of the aircraft is called the heart of the aviation industry - the overall backwardness of the engine has been delaying the development and installation process of my country's armed helicopters. The Wuzhi 10 project, which began in the 1990s, suffered twists and turns due to the engine. The engine power used for WZ-10 is still less than 1000kW, which is more than 60% lower than the 1662kW engine of the same kind of ...
