Embodiment Construction

[0021] like Figure 1-2 As shown, a magnesium oxide mineral insulated rigid heating special cable includes a solid conductor 1, a magnesium oxide mineral insulating layer 2, a magnetic steel strip layer 3 and a FEP sheath 4, and the magnesium oxide mineral insulating layer 2 is wrapped in the solid On the conductor 1 , the magnetic steel strip layer 3 is provided on the outer circumference of the magnesium oxide mineral insulating layer 2 , and the outer circumference of the magnetic steel strip layer 3 is covered with a FEP sheath 4 .

[0022] Specifically, the solid conductor 1 adopts a single solid copper wire.

[0023] Specifically, the magnesium oxide mineral insulating layer 2 is formed by heating and calcining the compacted magnesium oxide powder. Specifically, the magnesium oxide mineral insulating layer is any one of magnesium oxide, silicon dioxide, mica powder, and kaolin. several mixtures. The mixture can be used in cables, and is coated on the outer peripheral s...

Abstract

A magnesium oxide mineral insulated rigid heating special cable disclosed by the present invention comprises a solid conductor, a magnesium oxide mineral insulating layer, a magnetic steel belt layer and an FEP sheath, the magnesium oxide mineral insulating layer wraps the solid conductor, the magnetic steel belt layer is arranged on the periphery of the magnesium oxide mineral insulating layer, and the FEP sheath is arranged on the periphery of the magnetic steel belt layer. The periphery of the magnetic steel belt layer is coated with an FEP sheath. The cable is simple in structure, more excellent in corrosion resistance and heat resistance, and small in brittleness; when being electrified, the conductor and the magnetic steel belt layer generate a strong eddy current effect, so that the magnetic steel belt layer emits heat, the oil pumping well pipe is heated, the oil pumping efficiency is ensured, the effect is particularly obvious in cold winter, and the heating device is particularly suitable for heating operation of the oil pumping well pipe of an oil well.

Description

technical field [0001] The invention relates to the field of special cables, in particular to a magnesium oxide mineral insulated rigid heating special cable. Background technique [0002] Petroleum crude oil is very viscous, and as the ambient temperature decreases, the flow rate of crude oil becomes slower when pumping in the well, which greatly affects the pumping efficiency and crude oil output of each well. For now, most wells are taking their course with little action. How to develop a special mineral insulated steel heating cable, so that the heat generated by the heating cable can be transferred to the oil pipe, so as to solve the problems of unsmooth oil pumping, low flow rate and low output. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a magnesium oxide mineral insulated rigid heating special cable to solve the problems of unsmooth pumping and low flow rate. [0004] In order to solve the above-mentioned technical problem...
