Abstract

The invention discloses an oil pump leading cable for an offshore oil platform, which comprises conductors and insulating layers. Each of the three conductors is wrapped in one insulating layer; after being wrapped in the insulating layers, conductor cores are intertwisted and bundled to form a cable core; the bundled cable core is wrapped in a belting layer, wherein flame-retardant glass fiber ropes are arranged between the belting layer and the insulating layers as a filling layer; the belting layer is wrapped in a shielding layer; the shielding layer is wrapped in a high-flame-retardant oil-slurry-resistant chloroprene rubber inner lining layer; and the inner lining layer is wrapped in an armored layer and an oversheath. The sectional area of each conductor is 10-25mm <2>. The oil pump leading cable of the invention satisfies low-smoke, halogen-free, flame-retardant and other performance indexes of ocean engineeering cables, and at the same time solves problems including oil resistance, slurry resistance and wear resistance.

Description

technical field [0001] The invention relates to the cable industry, in particular to an oil pump leading cable for an offshore oil platform. Background technique [0002] The development of my country's oil platform cables started in the 1980s. Under the upsurge of developing my country's offshore oil resources, Shanghai Cable Factory, Shenyang Cable Factory, Hongqi Cable Factory and other factories capable of manufacturing marine cables at that time had all developed cables for offshore oil platforms. However, at that time, the large-scale drilling and oil production platforms in my country's waters were basically foreign platforms. Foreign platforms generally proposed to use foreign platform cables, and domestic platform cables were almost completely rejected. [0003] Due to the high technical performance requirements of oil platform cables, domestic research and development started relatively late. In order to realize the localization of special cables for oil drilling...
