Abstract
The utility model discloses a supercritical-power-generation-used high-strength cable with composite fireproof layers and belongs to technical field of cable production. The cable comprises at least three twisted insulating cores and is characterized in that the insulating cores are wrapped in a polyester film main wrapping tape wrapped in a copper-wire-woven shielding layer. The copper-wire-woven shielding layer is wrapped in an inner fireproof layer wrapped in a steel-tape armoring layer. The steel-tape armoring layer is wrapped in an outer fireproof layer wrapped in a flame-retarding polyvinyl chloride outer sheath. Each insulating core comprises a conductor and a crosslinked polyethylene insulating layer wrapped round the conductor. The cable has good shielding performance and the steel-tape armoring is capable of preventing the cable from being destroyed when the cable suffers from impact of external force. The cable is applicable to places requiring high flame retarding performance in motion environment, the places such as a supercritical power plant or the like.
Description
Technical field
The utility model relates to the cable production technical field.
Background technology
Power plant, particularly supercritical generating plant require high, general cable for the anti-flammability of cable, even other cable of general flame retardant grade can not be applied to supercritical generating plant.
Summary of the invention
The utility model purpose is to propose preferably supercritical generating composite fire-proof floor height intensity cable of a kind of anti-flammability.
The utility model comprises at least three stranded group insulated wire cores, the total twining package tape of polyester film is set outside insulated wire cores, outside the total twining package tape of polyester film, the proof copper-wire braided screen is set, interior fireprotection layer is set outside the proof copper-wire braided screen, the steel-tape armouring layer is set outside interior fireprotection layer, outer fireprotection layer is set outside the steel-tape armouring layer, and fireprotection layer arranges the flame-proof polyvinyl chloride oversheath outward outside; The described insulated wire cores of respectively organizing comprises conductor, and is arranged on the outer crosslinked polyetylene insulated layer of conductor.
The utility model is with the insulating barrier of crosslinked polyetylene insulated layer as each group insulated wire cores, and the insulated wire cores of stranding adopts polyester film as always wrapped outward, also adopts double-deck fireprotection layer, adds steel-tape armouring, and outermost layer also arranges the flame-proof polyvinyl chloride oversheath.So, the characteristics of advantages of good shielding performance of the present utility model, and steel-tape armouring can prevent that cable from coming to harm when being subject to external impacts, be applicable to fire-retardant demanding place under the movement environments such as supercritical generating plant.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is provided with mutually four groups of stranded insulated wire cores 1, at the insulated wire cores 1 outer total twining package tape 2 of polyester film that arranges, at the total twining package tape 2 outer proof copper-wire braided screens 3 that arrange of polyester film, interior fireprotection layer 4 is set in that proof copper-wire braided screen 3 is outer, at the interior fireprotection layer 4 outer steel-tape armouring layers 5 that arrange, at steel-tape armouring layer 5 outer outer fireprotection layer 6, outside the fireprotection layer 6 outer flame-proof polyvinyl chloride oversheath 7 that arranges of arranging.Between four groups of insulated wire cores 1 in the total twining package tape 2 of polyester film inserts 8 is set.
Each is organized insulated wire cores 1 and comprises conductor 11, and is arranged on the crosslinked polyetylene insulated layer 12 outside the conductor 11.
