Abstract
The invention discloses a magnetic disturbance resistant shielding light flexible cable. The magnetic disturbance resistant shielding light flexible cable is formed by a control cable core, a galvanizing annealed copper conductor cable core and five layers of protective layers; two conductors and three layers of protective layers are arranged inside the control cable core; the two conductors comprise a galvanizing nickel conductor and a galvanizing aluminum conductor in a pressing wrapping mode; the interior of the galvanizing annealed copper conductor cable core is provided with fourteen galvanizing annealed copper conductors in a pressing wrapping mode and the three layers of protective layers in a lapping mode; the five layers of protective layers sequentially comprise a neoprene rubber insulating layer, an aluminum belt shielding layer, a copper belt shielding layer, an ethylene propylene rubber layer and a tinned copper belt armor polyolefin sheath layer from interior to exterior. The magnetic disturbance resistant shielding light flexible cable has the advantages of being strong in shielding performance, strong in magnetic disturbance resistance, high temperature resistant, applicable to petrochemical engineering equipment, good in conductive performance and good in insulating effect.
