Abstract
The present invention relates to the prodn of power cable and aims at simplifying the techn process. The techn scheme is that the drawn and twisted wire after preheated is first fed to three-extruder set, where three layers of conductor screening one, insulating one and insulator-screening one are extruded in one single process; the extruded layers after cooling are then cross-linked in thermostatic water tank; and the metal shielding layer and the isolating jacket are formed. The present invention has good application prospect.
Description
The invention belongs to the production technology of cable, especially silicane cross-linking process for power cable.
At present, crosslinked cable has all replaced aluminium bag paper insulation power cable, and crosslinked cable mainly contains three kinds of modes, 1 peroxide crosslinking, 2 radiation crosslinkings, 3 crosslinked with silicane, crosslinked with silicane has obtained promotion and application in the world with distinctive advantage, but the tired lock of production technology has increased product cost.
The crosslinked with silicane power cable production technology that the object of the present invention is to provide a kind of processing step to simplify.
Technical scheme of the present invention: conductor is behind drawing, the tight position of twisted wire, enter by what three extruders were formed and extrude unit through giving heat, make conductor shield, insulating barrier, insulation screen once extrude for three layers, after cooling, enter Water Tank with Temp.-controlled then and carry out crosslinkedly, carry out metallic shield at last, extrude separation sleeve.
Advantage of the present invention: owing to conductor shield, insulating barrier, insulation screen are once extruded for three layers, simplified processing step greatly, reduced production cost.The advantage of crosslinked with silicane is better than the characteristics of peroxide and radiation crosslinking in addition, can carry out crosslinked under sight normal temperature.Every performance of product all can reach the product request of national standard.
The production technology of crosslinked with silicane power cable is described in detail in detail in conjunction with the embodiments.
Conductor behind drawing, the tight position of twisted wire, gives heat earlier, and the temperature range of giving heat is 80 ℃～100 ℃, and present embodiment is got 90 ℃.Give and enter the unit of extruding that three extruders form after the heat, three extruders can be respectively φ 65, φ 150, φ 90 extruders, at first enter φ 65 extruders and squeeze conductor shield, the draw ratio of φ 65 extruders is that 20: 1 compression ratios are 25: 1, body temperature one, two, three districts are respectively 80 ℃, 100 ℃, 120 ℃, 125 ℃ of heads, enter φ 150 then, φ 90 extruders and two-shipper head, squeeze insulating barrier and insulation screen, the draw ratio of φ 150 extruders 25: 1, compression ratio 3: 1, the draw ratio of φ 90 extruders 20: 1, compression ratio 2.2: 1, grafted material and catalysis masterbatch add φ 150 extruders after with 95: 5 mixed, the silane material reaction finish be by vinyl trimethoxy silane is grafted to form on the ethylene chain intermediate then graft compound from φ 150 extruders, extrude.Extrude after cool off and enter Water Tank with Temp.-controlled and carry out crosslinkedly, carry out metallic shield at last, extrude separation sleeve, the cable core that three core strandings strand is made by extruding oversheath, is finished whole technical process behind the dress cable again.
