Abstract
The utility model discloses a petro-chemical control power cable. The cable mainly comprises a main wire core, a semiconductive filling layer, a polytetrafluoroethylene insulating layer, a tined copper wire shielding layer, an aluminium strip armor layer and a sheath. The main wire core is divided into three groups which are stranded and extruded inside the semiconductive filling layer. The semiconductive filling layer is coated by the polytetrafluoroethylene insulating layer. The polytetrafluoroethylene insulating layer is coated by the tined copper wire shielding layer. The tined copper wire shielding layer is coated by the aluminium strip armor layer The petro-chemical control power cable provided by the utility model has the advantages of high corrosion resistance, good dielectric properties, aging resistance and low friction coefficient, and can be used at a temperature of 180-250 DEG C for a long time. The cable is applicable to the industries of ships and petro-chemistry.
