Device for coating external insulation of 1200 DEG C high-temperature-resistant cable and use method

Abstract

The invention relates to a device for coating external insulation of a 1200 DEG C high-temperature-resistant cable and a use method. The device comprises a gluing pot, a mold frame and a dryer, wherein the center lines of a wire hook on the gluing pot, a die hole on the lower die and a lower wire groove on a dryer base are on the same horizontal plane and on the same straight line. The method comprises the steps of manufacturing the high-strength nickel-plated copper alloy conductor, wrapping the high-purity quartz fiber woven inner insulator, preparing the mica coating, coating and sintering. The high-purity quartz fiber woven inner insulation and the high-temperature-resistant mica coating outer insulation can be sintered into a whole to form an insulation layer, the insulation layer is coated on the outer surface of the high-strength nickel-plated copper alloy conductor, the 1200 DEG C high-temperature-resistant cable is manufactured, the 1200 DEG C high-temperature-resistant cable can resist the high temperature of 1050 DEG C for a long time and can resist the high temperature of 1700 DEG C for a short time, and the 1200 DEG C high-temperature-resistant cable has the advantages of being soft, small in outer diameter and the like. The device provided by the invention is matched with various types of machines such as horizontal cable winches, wrapping machines, rewinding machines and the like for use.

Description

technical field [0001] The invention relates to the production field of high-temperature cables, in particular to a device and a use method for outer insulation coating of 1200°C high-temperature-resistant cables. Background technique [0002] At present, the common high-temperature-resistant cables on the market are generally divided into two types. One is the high-temperature-resistant cable that uses alkali-free glass fiber + high-temperature-resistant varnish as insulation. For the long-term use environment of 850°C, there is another kind of SiO 2 Extrusion-structured high-temperature-resistant cables have high hardness and large bending radius, and take up a lot of space during use and storage. When the use space or installation space is narrow, it cannot be used or installed normally. Contents of the invention [0003] In view of the deficiencies in the prior art, the present invention provides a device and method of use for outer insulation coating of 1200°C high t...
