Summary of the invention
In view of this; the purpose of this utility model is to provide a kind of colour band split-phase type one-step silane cross-linked polyethylene insulated fireproof power cable that can overcome the defective of prior art; it is direct wrapped fire-resistant isinglass belt and the polyester belt that shields outside the conductor of each crosslinked polyetylene insulated core; in order to improve the fire resistance of cable; superscribe insulating barrier again in the periphery of polyester belt and extruded the thin bar of a colour band phase-splitting at this surface of insulating layer; to satisfy cable phase-splitting requirement when mounted; simultaneously; periphery in this insulated wire cores is wrapped up nonwoven fabrics successively; the protection against rodents armour; protective layers such as oversheath are to improve the security reliability of cable.
For achieving the above object; the technical solution of the utility model is: described colour band split-phase type one-step silane cross-linked polyethylene insulated fireproof power cable comprises insulated wire cores; this insulated wire cores comprises conductor and the wrapped successively flame retardant coating in this conductor periphery, the polyester belt that shields and insulating barrier; surface of insulating layer in this insulated wire cores has also extruded the thin bar of a colour band phase-splitting, wraps up nonwoven fabrics, steel-tape armouring layer in this insulated wire cores periphery selectively successively and is wrapped in outermost oversheath.
Colour band split-phase type one-step silane cross-linked polyethylene insulated power cable of the present utility model makes the fire resistance of product be greatly improved owing to direct wrapped fire-resistant isinglass belt outside the conductor of insulated wire cores and the polyester belt that shields.Baofeng company carries out GB18380-2001 or IEC60331 according to the difference of order goods requirement or users at home and abroad respectively to the examination of fire resistance.Through this cable being carried out routine test according to above-mentioned relevant regulations, the equal conformance with standard requirement of its every performance index.Simultaneously, this cable also has characteristics and good power supply reliabilities such as protection against rodents, after through trial-production, trial run, now successfully introduces to the market, and is subjected to users' favor.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of first embodiment of the present utility model;
Fig. 2 is the cross section structure schematic diagram of second embodiment of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
See also Fig. 1: be a specific embodiment of the present utility model.This colour band split-phase type one-step silane cross-linked polyethylene insulated fireproof power cable is 3 core cables, and it is by 3 colour band split-phase type insulated wire cores 1 stranded forming, and the gap between each insulated wire cores 1 is filled with pp rope filler 2.Each insulated wire cores 1 comprises conductor 11 and the wrapped successively flame retardant coating 13 in these conductor 11 peripheries, the polyester belt 14 that shields and insulating barrier 12, has also extruded the thin bar 10 of a colour band phase-splitting on the surface of this insulating barrier 12.Wrap up nonwoven fabrics 3 and oversheath 6 successively in this insulated wire cores 1 periphery.
As shown in Figure 2, be the embodiment of another multicore cable of the present utility model.Multicore cable herein is by 5 insulated wire cores, 1 stranded forming, and the gap between each insulated wire cores 1 is filled with pp rope filler 2.Each insulated wire cores 1 comprises conductor 11 and the wrapped successively flame retardant coating 13 in these conductor 11 peripheries, the polyester belt 14 that shields and insulating barrier 12, has also extruded the thin bar 10 of a colour band phase-splitting on the surface of this insulating barrier 12.Wrap up nonwoven fabrics 3, steel-tape armouring layer 5 successively and be wrapped in outermost oversheath 6 in this insulated wire cores 1 periphery.
Described flame retardant coating 13 adopts two-layer phlogopite band or synthetic mica tape, and overlapping wrapped on conductor 11, Duplication is 50%.For avoiding its mechanical damage in the process of extruding, need be at the wrapped again one deck polyester belt 14 in the periphery of this flame retardant coating 13, Duplication is between 15%～20%.
The thickness of the thin bar 10 of described colour band phase-splitting is about 1/20th of insulating barrier 12 thickness, and width is about 1/10th of insulating barrier 12 overall circumferences.
The insulating material of described insulating barrier 12 adopts one-step silane cross-linked polyethylene, installation needs according to multicore cable, extrusion equipment adopts the Three layer coextruding one step crosslinked with silicane production line from Finland Nokia-Mai Raphael company import, is used for producing colour band split-phase type one-step silane cross-linked polyethylene insulated wire cores.Whole production line adopts system controlled by computer, and shows, follows the tracks of the particulars in the production process at any time, can be at any time to becoming the abnormal conditions in the product process to carry out the technology adjustment.
For preventing that minute impurities or dust from entering in the insulating material, Insulation Material must adopt gravity blanking through 1000 grades of purifications, can guarantee raw-material degree of purity, makes the crosslinked polyetylene insulated electrical property that makes obtain better controlled.
Crosslinking agent adopts the import liquid silane, is injected automatically at the hopper neck by technological requirement by the automatic implanter of silane.Can make Insulation Material and silane mixture even, make that to make the crosslinked polyetylene insulated degree of cross linking qualified, avoid crossing crosslinked or the degree of cross linking is not enough.The automatic implanter of its silane is the patented product of our company.
