Zc-MMMCXI
Peroxide transversis connexio polyethylene in tres dimensivas retis thermoplasticis convertit, resistentiam caloris liberans, vires mechanicas, et diuturnum firmum quod PE uncrossinnexum aequare non potest . Peroxide corrumpit ad extrusionem caloris ad radicalia libera generanda, quae atomi hydrogenii abstracti a PE catenis carbonis carbonis crosslinks formant..
| Peroxide | Decomposition Temp. | Typical Dosis | Commoda | limitationes |
|---|---|---|---|---|
| DCP (Dicumyl Peroxide) | 175-185°C | 1.5-3.0 phr | Maximum efficientiam, cost-effective | Moderatus aestus periculo, flaventia |
| DHBP (2,5-Dimethyl-2,5-di-tert-butylperoxyhexane) | 170–180°C | 1.5-3.0 phr | Libratum efficientiam, humilis LEVITAS | Paulo altius quam DCP pretium |
| BIPB (Bis(tert-butylperoxy) diisopropylbenzene) | 175-185°C | 1.5-3.0 phr | Alta puritas, humilis odor | Superiore pretio, limitata disponibilitate |
Electio logica: DCP electio est industria-vexillum pro funibus ≤35kV, optimum statera perficiendi, processabilitatis et sumptus offerens . Pro muris velitis crassioribus (>5mm) vel altioribus intentionis generibus, considera DHBP vel BIPB pro salute adustione aucta et contenta volatilia inferiora. Pro funes usque ad 35kV, incipies ab 2.0-2.5 phr DCP; auget ad 3.0 phr pro densior velit.
| Cable Rated intentione U / U | Typical Insulation Crassitudo | commendatur Compositum Grade |
|---|---|---|
| 3.6/6 kV | 2.5 mm | Standard MV gradus |
| 6/10 kV | 3.4 mm | Standard MV gradus |
| 8.7/15 kV | 4.5 mm | Standard MV gradus |
| 12/20 kV | 5.5 mm | Standard MV gradus |
| 18/30 kV | 8.0 mm | Consectetur munditia gradus |
| 26/35 kV | 10.5 mm | ZC-3111 / ultra gradus mundi |
Ad retinacula 26/35kV, insulatio crassitudo typice pervenit ad 10.5mm pro sectionibus transversis 50mm² et supra. Crassior insulatio postulat altiorem contentum gelationis (>85%) et arctiorem imperium peroxidum migrationis et productorum remotionem in degassing..
Gel content directe indicat crosslinking perfectionem. Nam mediae voltagenae retinacula (≤35kV), scopum gel contentum ≥85% per ASTM D2765 est . ZC-3111 gel contentum typicam tradit 86%. Incompleta crosslinking eventus in imminutis viribus mechanicis, inferioribus dielectricis peractis, augetur periculum funis defectum sub lacus scelerisque. Monitor gel contentus ad omnem massam productionis.
Peroxide crosslinking moderatio accurata temperatura per extrusionem et gradus sanandi requirit. Suadeo dolium temperatum pro ZC-3111 est:
| Zona | Pascentium Section | Compressiones | Homogenization Section | Model Section |
|---|---|---|---|---|
| Temperatus (°C) | 90-100 | 100-110 | 105-115 | 110-120 |
CV (vulcanization continua) temperatura tubi 160-190°C servanda est pro peroxide integra compositione et crosslinking . Compositum compatible cum tribus-circulis construentibus lineae conventionales cum ducta ratione 20 ad 30:1.
Insulatio munditia composita critica est ad medium funem voltationis faciendum. Impura et contaminantium missionem partialem causare possunt, praematuram defectum inducens. ZC-3111 in systemate clauso producitur cum detrimento-in-gravium pastorum ut accuratio stabilis et minimalis contaminatio curet. Impuritas particulae magnitudo per batch verificabitur distributio. Pro 35kV funes, gradus ultra-mundi cum strictiore particula computa limites commendantur.
Peroxide connexio generat volatilia per-producta (exempli gratia, acephenone, alcohole cumyl) quae per processum decolorans removeri debet. Degassing imperfecta causare potest evacuationes, odores, et effectus dielectrici reduci. Degassing typice peragitur ad 60-80°C pro 24-72 horis, secundum crassitudinem velit. Pro 35kV retinacula cum 10.5mm velitatione extensa requiri degass.
Adustione (praematura crosslinking in extrusionem) causare potest defectus superficies et apparatu venenatis. Compositum debet habere ustum tempus (ts2) ex >8 minutis ad processus temperatus . Copia ZC-3111 ad cella temperies in mundo, sicco et in ambitu ventilato. Optime utendum est intra sex menses a die productionis. Packaging est 500kg per sarcinam, interiore structa cum plastic sacculo obsignato cinematographico, lobortis limato cum lance in fundo.
