Problems solved by technology

However, this type of cable has great disadvantages, such as heavy weight, large outer diameter, not easy to bend, limited use occasions, complicated cable terminal processing, and a waste of time. At the same time, the lead sheath contains a large amount of lead metal, which is toxic and harmful to the environment and human body. Great health hazard

Abstract

The invention relates to a hydrocarbon-ageing-resistant power cable for a petrochemical unit and a manufacturing method of the hydrocarbon-ageing-resistant power cable. The manufacturing method includes the steps that an insulating layer is evenly extruded on the periphery of each stranded copper conductor to form a power cable insulated wire core; a plurality of power cable insulated wire cores are stranded to form a power cable core. The periphery of the power cable core is sequentially wrapped by a flame-retardant fireproof longitudinal wrapping tape, an aluminum foil composite shielding tape, a hydrocarbon-ageing-resistant inside liner, a nylon inner sheath and a hydrocarbon-ageing-resistant outer sheath. The aluminum foil face of the aluminum foil composite shielding tape faces inwards and the inner side of the aluminum foil face of the aluminum foil composite shielding tape is provided with copper wire current steering wires. The components of the inside liner and the components of the outer sheath respectively comprise, by weight, 15 parts of PVC-SG2, 5 parts of NBR3305, 3-7 parts of adipic acid propylene glycol polyester,2-3 parts of epoxidized soybean oil, 0.6-1 part of barium stearate, 1-1.5 parts of lead sulfate tribasic, 0.05-0.1 part of diphenol propane, 3-5 parts of antimonous oxide, 0.1-0.5 part of chlorinated paraffin-52 and 0.3-0.5 part of dicyclopentadienyl iron. The hydrocarbon-ageing-resistant power cable is capable of resisting hydrocarbon ageing, small in external diameter and light in weight.

Description

technical field [0001] The invention relates to a power cable, in particular to a hydrocarbon aging-resistant power cable for petrochemical equipment. The invention also relates to a method for manufacturing a hydrocarbon aging-resistant power cable for a petrochemical device. Background technique [0002] The petrochemical plant area contains a large amount of hydrocarbons such as oil, chemical solvents, flammable gases, etc. In order to ensure the safety of electrical work on site, it is necessary to use cables that can withstand the corrosion and aging of hydrocarbons for a long time and operate safely. The prior art uses airtight lead-clad sheathed cables, which have good corrosion resistance and can effectively isolate hydrocarbons. However, this type of cable has great disadvantages, such as heavy weight, large outer diameter, not easy to bend, limited use occasions, complicated cable terminal processing, and a waste of time. At the same time, the lead sheath contains...
