Abstract

A method for manufacturing a corrosion-resistant submersible pump cable includes such step as conductor treatment, coating adhesive, extruding insulating lay, stranding, extruding sheathing layer, coating corrosion-resistant layer and armoring. The submersible pump cable made by the method comprises a conductor, an insulation layer, a sheath layer, an anticorrosion layer and an armor layer from inside to outside; The conductor and the insulating layer are bonded by an adhesive; Between that insulate layer and the sheath lay, carbon fiber is used for filling; The number of conductors shall notbe less than 3, and each bundle of conductors shall be formed by stranding not less than 26 copper wires. The invention aims at the technical problems that the existing submersible pump cable has poorcorrosion resistance and short service life, is easy to be swollen by heat, increases the outer diameter error and is difficult to control the roundness of the armor, and the like. The invention hasthe advantages of long service life, high precision of outer diameter control, high temperature resistance and corrosion resistance, etc.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a corrosion-resistant submersible oil pump cable and a manufacturing method thereof. Background technique [0002] The submersible pump cable is a special cable used in conjunction with the submersible electric pump unit. The submersible pump power cable laid in the oil well can be divided into two types: round and flat. Limited by the narrow space of the oil well casing, the power cable of the submersible pump is usually flat. Since the flat cable has an asymmetric structure, when power is transmitted, the electromagnetic induction caused by the imbalance of the magnetic field will cause hysteresis loss and heat the cable. When the size of the oil well casing permits, the round cable should be used. The electromagnetic field generated by the symmetrical round cable is evenly distributed, the mutual interference is small, and the electromagnetic compatibility is good. It is also ...
