Abstract

The invention relates to a heat tracing oil-submerged pump cable. The cable comprises a conductor, and the conductor is formed by twisting a pure copper wire and a copper-nickel alloy wire. A high-temperature-resistant belt is tightly wrapped outside the conductor, a high-temperature-resistant insulating belt is wrapped outside the high-temperature-resistant belt, an insulating layer is extruded outside the high-temperature-resistant insulating belt, an inner sheath is extruded outside the insulating layer, an oil-resistant layer is wrapped outside the inner sheath, and a reinforced oil-resistant layer is woven outside the oil-resistant layer. The use temperature of the cable is increased, heat is diffused into petroleum, after the temperature of the petroleum is increased, the viscosity is reduced, and exploitation is more convenient.

Description

technical field [0001] The invention relates to a cable, in particular to a submersible oil pump cable. Background technique [0002] Petroleum is our important resource, which has been exploited and used all the time. The viscosity of oil determines the difficulty of extraction. When exploiting oil with relatively high viscosity, the pumping load is relatively large, and it is easy to cause blockage of pipelines. The viscosity of oil decreases with the increase of temperature, and generally the temperature can be reduced by half when the temperature increases by 10°C. Therefore, during the operation of the cable, the heating of the conductor is used to heat the oil to reduce its viscosity and provide convenience for mining. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to overcome the deficiencies in the prior art and provide a heat-tracing latent cable that increases the operating temperature of the cable and diffus...
