The present invention discloses a copper conductor silicone rubber insulated cable which is formed by 19 copper conductors, a filling layer, a copper tape shielding layer, a nitrile insulating layer, a silicone rubber insulation layer, an aluminum tape shielding layer, a neoprene rubber sheath layer and a steel tape armored polyethylene sheath. The 19 copper conductors are twisted together and are coated by the filling layer which is coated by the copper tape shielding layer. The copper tape shielding layer is coated by the nitrile insulating layer which is coated by the silicone rubber insulation layer which is coated by the aluminum tape shielding layer. The cable has the advantages of excellent insulating shielding performance and strong tear resistance performance and is suitable for the field of aviation, power generation, metallurgy and chemical industry, and the cable also has the advantages of high power transmission capability, high temperature and cold resistance and acid and corrosion resistance.
