Elastic expansion cable for soot blower

Abstract

The invention discloses an elastic expansion cable for a soot blower, which comprises a conducting wire core consisting of tinned copper wires. The wire core is made by covering an insulating layer made of a silicon rubber complex outside the conducting wire core; a plurality of vulcanized wire cores in different colors form a cable core; a sheath made of the silicon rubber complex covers outside the cable core; the elastic expansion cable consists of the vulcanized and shaped cable core twisted helically and comprising the sheath; the conducting wire core is made by the bunch stranding and the compound stranding of the tinned copper wires; and the cable core consists of 4-7 wire cores in different colors. The elastic expansion cable for the soot blower overcomes the defects of the conventional cables for the soot blower, can be normally used in an environment at -40 to +25 DEG C, has the advantages of prolonged service life, relatively high elasticity, lasting elasticity without deformation and convenient use, and further ensures the normal work and the safety production of the soot blower.

Description

technical field [0001] The invention relates to a cable, in particular to an elastic expansion cable for a soot blower. Background technique [0002] The insulation layer and sheath of the existing domestic cables for sootblowers are generally extruded from ordinary rubber, which is not resistant to high temperatures. Because sootblowers usually work for a long time, their insulation layers and sheaths are prone to accelerated aging in high temperature environments. The resulting cable has a short service life and needs to be replaced frequently, and the cable has poor elasticity and is prone to deformation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an elastic expansion cable for soot blowers, which overcomes the defects of existing cables for soot blowers, can be used normally in an environment with a temperature of -40°C to +250°C, and prolongs the service life , with high elasticity, long-lasting elasti...
