Aluminium-alloy conductor oil-submersible cable

The utility model discloses an aluminium-alloy conductor oil-submersible cable, and the cable comprises three conductors. The cable is characterized in that the conductors are aluminium-alloy conductors; the outer layer of each aluminium-alloy conductor is wrapped by an insulating layer; the outer side of each insulating layer is wrapped by a nitrile rubber sheath layer; the outer side of each nitrile rubber sheath layer is wrapped by a steel-tape armored cushion layer; and the outer sides of three steel-tape armored cushion layers are wrapped by a steel-tape armored layer. The diameter of the aluminium-alloy conductors 1 is about 5.65 mm, and the cable can completely replace a 16mm copper conductor cable (the diameter is 4.62 mm) in practical application. The cable can meet the requirements of electrical properties and physical properties of conductors, also can effectively alleviate the shortage of nonferrous metals, is simple in manufacture technology, is light in weight, is convenient to install and use, and is lower in production cost.
