Corrosion-resistant cable with long service life

Abstract

Provided is a petroleum platform comprehensive cable, comprising power cores and a rubber sheath wrapping the power cores; each power core comprises a conductor and an insulation sleeve wrapping the conductor; the conductor is composed of a plurality of stands of tinned copper wires and carbon fibers uniformly distributed in the tinned copper wires and provided with silicon dioxide coatings; PEEK is filled between the insulation sleeves and the conductors; the inner surfaces of the insulation sleeves are coated by film polyester layers. The cores have the characteristics of low wire loss, high conductivity and small sag, and leads possess much lower sag characteristics compared with routine leads, allow high work temperatures, and have the characteristics of large carrying capacity, light weight, corrosion resistance and long service life.

Description

technical field [0001] The invention relates to a flexible cable for an oil platform. Background technique [0002] The Chinese Patent Publication No. CN 201956092U discloses a control cable for oil platforms, including a cable core, characterized in that: the cable core is composed of several insulated cores and a steel wire rope arranged between the insulated cores. The steel wire rope is extruded with TPE insulation, the insulated wire core is composed of a copper conductor extruded with a TPE insulation layer; the cable core is extruded with a TPU inner sheath layer, and the inner sheath layer is armored with aramid fiber The aramid fiber is extruded and wrapped with a TPU outer sheath layer; this technical solution has good electrical transmission performance, softness, tensile strength, oil resistance, high temperature resistance, low temperature resistance, and Friction and lower cost and other advantages. However, the wire core has low tensile strength and low cond...

AI Technical Summary

Problems solved by technology

However, the wire core has low tensile strength and low electrical conductivity. Especially in the use of oil platforms, the environment is relatively harsh, and the quality requirements for the wire core are high. The general wire core cannot meet the requirements of the oil platform and needs to be improved.
