Power cable for ethylene propylene rubber insulating ship

Abstract

The invention discloses a power cable for an ethylene propylene rubber insulating ship. The power cable comprises a conductor, an insulating layer, an insulation shielding layer, a tape layer, an armoring layer and a sheath layer, and is characterized in that the insulating layer is arranged at the outside of the conductor, so that an insulating wire core is formed; the tape layer, the armoring layer and the sheath layer are sequentially arranged at the outside of the insulating wire core; the insulating layer is prepared from the following raw materials: ethylene propylene rubber, zinc dibutyl dithiocarbamate, polybutadiene, vinyl chloride-vinyl acetate copolymer, butyl chlorocarbonate, dimethylaminoethyl acrylate and the like. The power cable disclosed by the invention has the advantages that good flame resistance, high ageing resistance, high working stability and high reliability are achieved; the insulating layer has excellent flame resistance and excellent insulation property by means of improving the raw materials of the insulating layer, so that the whole service life is long.

Description

Technical field [0001] The invention relates to an ethylene-propylene rubber insulated marine power cable, which belongs to the technical field of wire and cable. Background technique [0002] In the long-term work of power cables, it is easy to accumulate heat and cause fires. The main cause of death in fires is not the direct burning of flames, but the smoke generated when materials are burned. These smokes not only produce large amounts of toxic substances, but also Causes people to suffocate, which is the main cause of death due to fire, and most of the existing power cable materials will produce a lot of smoke and toxic substances when they burn, and these are mostly organic polymers, which are easy to burn, so in case of fire Encouraged the fire and caused greater losses. Summary of the invention [0003] The purpose of the present invention is to provide an ethylene-propylene rubber insulated marine power cable, which has good flame-retardant performance, and strong aging ...

[0002] In the long-term operation of power cables, it is easy to accumulate heat and cause fires. The main factor causing death in fires is not the direct combustion of flames, but the smoke generated when materials are burned. These smokes not only produce a large amount of toxic substances, but also can This is the main cause of death due to fire, and most of the existing power cable materials will produce a lot of smoke and toxic substances when burned, and these are mostly organic polymers, which are easy to burn, so in the event of a fire fueled the fire and caused more damage
