Abstract

The present invention relates to an explosion-proof sheath for a wire and a cable and a manufacturing method thereof. The explosion-proof sheath is formed by bonding an aluminum alloy matrix material and a stainless steel round tube by a ceramic high temperature resistant adhesive. At the time of manufacture, the explosion-proof sheath is obtained by aluminum alloy melt preparation, aluminum alloy melt foaming processing, aluminum alloy matrix material molding, ceramic high temperature resistant adhesive preparation, nano microporous aluminum alloy matrix material and stainless steel tube composition. According to the explosion-proof sheath, the mechanical performance of the metal sheath is greatly improved, the high temperature resistant ability of the metal sheath is improved obviously, the ability of thermal shock resistance of the metal sheath in a high temperature explosion environment is greatly improved, the flameproof performance of the wire and cable is improved significantly, and the application of the wire and cable is safe.

Description

technical field [0001] The invention belongs to the field of power transmission and distribution line equipment, in particular to an explosion-proof sheath for wires and cables and a manufacturing method thereof. Background technique [0002] With the rapid development of my country's industrial automation, practical applications have higher and higher requirements for the safety performance of communication, monitoring, detection, alarm and control systems. Especially for the lines used in the fields of coal mine, petroleum, chemical industry and textile, it is required to have the characteristics of ensuring the normal operation of the line in the explosive environment. How to apply new materials and new processes to manufacture high-performance jackets that can protect the internal components of wires and cables in explosive environments is of great significance. [0003] Chinese patent CN203013326U discloses an intrinsically safe alloy sheathed explosion-proof cable, wh...
