Abstract
The utility model relates to a cross-linking polyethylene insulation control cable, which comprises a conductor, an insulation layer coated on the outside of the conductor, a filler, a belting and an outer sheath. The control cable is formed by a plurality of conductors articulated with each other, and the non moisture absorption filler is filled in the spacing between each conductor, and the outside layer is tightened with the belting, and wrapped with the outer sheath. The insulation layer is made by a gait silane cross-linking polyethylene. Compared with the traditional PVC plastic, the electricity property and the physical property of the insulation material of the utility model are better and more reliable. In addition, the gait silane cross-linking polyethylene has the advantages of good thermal stability, light weight and easy heat emission.
Description
Technical field
The utility model relates to a kind of power transmission cable, particularly relates to a kind of crosslinked polyetylene insulated control cable.
Prior art
Characteristics such as the insulation control cable is simple in structure with it, technology realizes easily, with low cost go up very universal often at present.Traditional control cable generally all adopts the PVC plastics as insulating layer material, because the PVC insulating material contains a large amount of halogens, discharges halogen acid gas during burning, and instrument and meter and equipment is on every side all had serious corrosivity, and human body is also caused very big injury.And every performance index of PVC also to be nothing like crosslinked polyethylene superior, thereby, more and more be subjected to people's welcome as the control cable of insulating layer material with crosslinked polyethylene.
Silane crosslinking process is divided into one-step method and two-step method according to the difference of the mode of production, and silane grafting and extrusion molding are finished in one procedure is called one-step method, and that finishes in two procedures is called two-step method.Two-step method is made material by the grafting of raw material producer earlier, the precrosslink phenomenon often appears in manufacture process, its every performance index often do not reach the corresponding national standards requirement, and this just makes two-step method produce the crosslinked polyethylene insulation material control cable and has been subjected to certain restriction, can not promote the use of.And one-step method is few because of operation, and grafting, moulding are once finished, no precrosslink phenomenon, and product quality is protected easily.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of crosslinked polyetylene insulated control cable that can overcome the defective of prior art, it adopts one-step silane cross-linked polyethylene as insulating layer material, makes the electrical property of cable and physical property be improved comprehensively.
For achieving the above object, the technical solution of the utility model is: described crosslinked polyetylene insulated control cable comprises that conductor and bag tie up insulating barrier, filler, band and the oversheath at this conductor outer surface, this control cable is by the stranded stranding of several conductors, gap between each conductor is filled with the non-hygroscopic filler, skin is tightened with band, wraps up with oversheath again; Described insulating barrier is made by one-step silane cross-linked polyethylene.
The insulating material of branch cable of the present utility model adopts one-step silane cross-linked polyethylene, and its electrical property and physical property are compared better and reliable with traditional PVC plastics.In addition, it is superior that one-step silane cross-linked polyethylene also has thermal stability, advantage such as in light weight, easy heat radiation.
Description of drawings
Fig. 1 is the structural representation of first embodiment of the present utility model;
Fig. 2 is the structural representation 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 crosslinked polyetylene insulated control cable comprises conductor 1 and wraps the insulating barrier of tiing up at this conductor 1 outer surface 2, this control cable is by 7 conductors, 1 stranded stranding, gap between each conductor 1 is filled with non-hygroscopic filler 3, skin is tightened with band 4, again with oversheath 6 parcels, stranding deviation in roundness≤10% of this control cable.
Accompanying drawing 2 is depicted as another embodiment of the present utility model, and it has increased one deck armour 5 between the band 4 of first embodiment and oversheath 6.
Insulating barrier recited above 2 is made by one-step silane cross-linked polyethylene.Insulating material adopts low-density polyethylene material, and its performance index satisfy the GB12706-91 standard, and the crosslinking agent of making material is a liquid silane, after grafting in extruder, carry out warm water crosslinking, the degree of cross linking reaches 80～90%, wherein the warm water water temperature is 90 ± 5 ℃, and crosslinking time is 4～6 hours.
Inventor Baofeng Cable Co., Ltd., Hebei of the present utility model and Hebei supernatural power technical machinery company have developed one-step method silanes crosslinked production line jointly, this production line adopts totally-enclosed oven dry, purifies feeding system, color masterbatch, the reinforced autonomous system of silane, the electronics metering, the touch microcomputer automatic control system of PLC calculates and the storage technology parameter automatically, is furnished with the online measuring apparatus of diameter of German Xi Kela production moral simultaneously, can carry out overall monitor to product, break down and report to the police automatically.
Following table 1 is the insulation property contrast of one-step silane cross-linked polyethylene and PVC insulating material.In addition, one-step silane cross-linked polyethylene also has advantages such as thermal stability is superior, in light weight, easy heat radiation.
Described oversheath 6 adopts 70 ℃ of PVC protective cover materials, and its performance index satisfy the GB9330 standard.
Described conductor 1 adopts 1 class conductor, the defectives such as burr, sharp edge and projection that conductive surface should bright and clean, no greasy dirt, not damaged insulate, and its every performance index satisfy the GB/T3956-1997 standard.
