When the cable system is laid underground, in an underground passage or in water that is prone to water accumulation, in order to prevent water vapor and water from entering the cable insulation layer and ensure the service life of the cable, the cable should adopt a radial impervious barrier layer structure, which includes a metal sheath and a metal-plastic composite sheath. Plumbum, aeris, aluminium et aliis metallum materiae communiter usus est ut metallum vaginae ad funem; A metallum-plastic compositum tape et polyethylene vagina formare metallum, plastic compositum vagina funus. Metal-plastic composite sheathing, also known as comprehensive sheathing, is characterized by softness, portability, and water permeability is much smaller than plastic, rubber sheathing, suitable for places with high waterproof performance requirements, but compared with metal sheathing, metal-plastic composite sheathing still has a certain permeability.
In Europae medium voltage cable signa ut HD DCXX S2: MMIX, NF C33-226, MMXVI, une (CCXVI) XX: MMXX, una-latus latera plastic operimentum in potestatem tape adhibetur ut comprehensive waterproof operimentum in potestate est ut a comprehensive wathoof operimentum in potestate est ut a comprehensive wathoof operimentum in potestate est usus ut comprehensive waterproof operimentum in potestate est ut comprehensive wathoof operimentum in potestate est quasi comprehensive wathoof operimentum in potestate est ut a comprehensive waterproof operimentum in potestatem tape. Et metallum iacuit unius, adligataplastic iactaret aluminium tapeEst in directum contactus cum insulating clypeus et ludit partes metallum clypeus simul. In Europaeae vexillum, necesse est temptare ex nudos vim inter plastic iactaret aluminium tape et funem vagina et portare ex resistente probat ut metiretur radiale aquae resistentia cable; Simul, etiam necesse est ut metiretur DC resistentiam plastic iactant aluminium tape ut metiretur facultatem portare brevis circuitu current.
I. classificatio de plastic iactaret aluminium tape
Secundum diversum numerum plastic film iactaret aluminium subiecta materia, potest dividi in duas species longitudinalis coating processus: duplex, plastic iactaret aluminium tape et unum plastic iactaret aluminium tape et singulis plastic iactaret aluminium tape et singulis plastic iactaret aluminium tape et singulis plastic iactaret aluminium tape et singulis plastic iactaret aluminium tape et singulis plastic iactaret aluminium tape et singulis plastic iactaret aluminium tape.
Comprehensive Waterproof et humorem-probationem tutela iacuit medium et humilis intentione potentia cables et optical cables composito ex duplici postesque plastic iactantes aluminium tape et polyethylene, polyolefin et alias scandalis ludit partes radialis aqua et humorem et humorem pythonicus tapetibus et radiale aqua et humorem et humorem et tortamur. Single-seesed plastic iactaret Aluminium tape est plerumque propter metallum scutum communicationis cables.
In quibusdam Europae signa, praeter quod usus est in comprehensive waterproof vagina, una-seesed plastic iactaret aluminium tape est etiam usus est ut metallum scutum ad medium intentione costi, et aluminium tapens et scutum est obvious sumptus commoda comparari scutedensem.
II. Longitudinal Wrapping processus of plastic iactaret aluminium tape
Longitudinal Wrapping processus aluminium-plastic compositis habena refers ad processus transformans plastic iactaret aluminium tape ex originali plana figura ad fistulam figura per seriem fingunt deformatio et vinculum tape. Duo marginibus de plastic iactaret aluminium tape sunt plana et lenis, in marginibus sunt vinculum arcte, et non est aluminium-plastic cerva.
In processus of mutantur in plastic iactaret aluminium tape de plana figura ad tubulosam figura potest esse intellexit per usura a longitudinalis involuti mori composito ex longitudinalis involventes cornu mori, linea stabilientem et inebriati mori. Et fluxus diagram de longitudinalis involuti colendo mori de plastic iactaret aluminium tape est ostensum est in sequentibus figure. Duo marginibus in tubulosam plastic iactaret aluminium tape potest esse religari per duo processibus, calidum vinculum et frigus vinculum.
(I) calidum vinculum processus
In scelerisque vinculum processus est utor plastic iacuit de plastic iactant aluminium tape ad mollire ad LXX ~ XC ℃. In the deformation process of the plastic coated aluminum tape, the plastic layer at the joint of the plastic coated aluminum tape is heated using a hot air gun or blowtorch flame, and the two edges of the plastic coated aluminum tape are bonded together using the viscosity after the softening of the plastic layer. Crustulum duos margines de plastic iactaret aluminium tape firmiter.
(II) frigus vinculum processus
Frigus in duplici generis est duplex, unum est addere longum stabile mori in medio Caliper mori et extruder caput, ut plastic tape et in iniustitiam in capite et exit ex Extruder in M. et aluminium-plastic compositum, et in ineunte et ex Extruder est in Firmam, et ex Extruder in Firmam in Member Platicum, et ex Extruder in Firmam, et Aluminium, Plastic ex Extruder in M. et Aluminium, Plastic ex Extruder in M. et Aluminium, Plastic Compositum in Meme, et Aluminium, Plastic ex Extruder in M. et Aluminium, Plastic Compositum statim ingreditur, et ad extremum in plastic ex parte stabilis, et aluminium, et exitum est ex parte in stabulo, et aluminium, plastic compositum statim ingreditur, et ad exitum, ex parte stabilis, et aluminium, plastic compositum statim ingreditur in plastic compositum, et in iniecerunt in Die Core post tulit de firmum mori. Extrusionem pressura de vagina materiam custodit tubulosam structuram de plastic iactaret aluminium tape et altum temperatus ex extruditur plastic molles plastic iacuit plastic operis aluminium tape ad perficiendam in plastic operis. Hoc technology est idoneam duplici, laminis laminated plastic iactaret aluminium tape, productio apparatu est simplex operari, sed forma processui est secundum universa est facile ad resilit.
Another cold bonding process is the use of hot melt adhesive bonding, hot melt adhesive melted by the extrusion machine in the longitudinal wrap horn mold position squeezed on one side of the outer edge of the plastic coated aluminum tape, the two edge positions of the plastic coated aluminum tape through the stable line and sizing die after the hot melt adhesive bonding. Hoc technology est idoneam utriusque duplex postesided plastic iactant aluminium tape et unum, postesque plastic iactaret aluminium tape. Eius fingunt dispensando et productionem apparatu sunt simplex operari, sed ejus vinculum effectus valde affectus est qualis est calidum liquescit tenaces.
Ut ad curare reliability de operatione funem ratio, metallum scutum esse electrically connexa cum tortor clypeus cable, ita et unum adligata plastic tunicas aluminium tape debet esse ut metallum clypeus clypeus. Exempli gratia, in calidum processu de quibus in charta est tantum idoneam duplici postesqueplastic iactaret aluminium tape, Dum frigus vinculum processus usura calidum adoratur tenaces est magis idoneam ad unum, seesque plastic iactaret aluminium tape.
