In the electrically used swelling layer which as a carrier of strength cable conduits for conducting can be carried out by means of a conductive swelling bandage made of conductive swelling with a plastic inner sheath, April / May 1987, pages 54 to
Pri kábloch na stredné napätie vysoké napätie so zosieťovanou izoláciou a s drôtovým tienením obklopujúcim vonkajšiu vodivú vrstvu je ďalej potrebné upraviť medzi vonkajšiu vodivú vrstvu a drôtové tienenie tlmiacu vrstvu.In the case of medium-voltage cables of high voltage with cross-linked insulation and with wire shielding surrounding the outer conductive layer, it is also necessary to provide a damping layer between the outer conductive layer and the wire shielding.
Tato tlmiaca vrstva môže byť vyhotovená napríklad z laminátu vytvoreného z vypenenej látky/rúna, ktorý sa ako pásik navinie s prekrývajúcimi sa okrajmi na vodivú vrstvu. Pre prípad, Že má byť oblasť tienenia upravená ako vodotesná v pozdĺžnom smere, to je má zabrániť prenikaniu vody v pozdĺžnom smere, môže sa ako tlmiaca vrstva použiť elektricky vodivé polyesterové rúno, pričom na tienenie sa umiestni nevodívé napúčavé rúno (DE-Z “Draht, 1982, Heft 4, strana 203).This damping layer can be made, for example, of a laminate formed from a foamed fabric / web, which is wound as a strip with overlapping edges onto a conductive layer. In the event that the screening area is to be made waterproof in the longitudinal direction, i.e. to prevent water in the longitudinal direction, an electrically conductive polyester web may be used as a cushioning layer, with a non-conductive swellable web (DE-Z 'Draht) , 1982, Heft 4, page 203).
Úlohou vynálezu je vytvoriť silnoprúdový kábel; ktorý má oblasť tienenia vyhotovenú tak, že v jednej výrobnej operácii je zaistené pripevnenie tieniacich drôtgv (najmä tieniacich drôtov spletených do tvaru SZ), dobré vyhotovenie tlmenia tienenia a zaistenie vodotesnosti v pozdĺžnom smere.It is an object of the present invention to provide a power cable; which has a shielding area designed in such a way that in one manufacturing operation it is ensured that shielding wires (in particular shielding wires braided in the shape of SZ) are secured, good shielding damping and waterproofing in the longitudinal direction.
Podstata vynálezu (Jvedenú úlohu splňuje silnoprúdový kábel s tienením vyhotoveným z drôtov, ktoré je umiestnené pod vonkajším plášťom na vodivej vrstve vyrobenej pretlačovaním, pričom medzi vodivou vrstvou a drôtmi tienenia je usporiadaná výplňová vrstva z vodivých a napúčavých páskov, ktorého podstatou je, že výplňová vrstva (5) z vodivých a napúčavých páskov pozostáva zo zložených vrstiev (51, 52) z rúna a vypenenej látky, kde vypenená látka leží smerom von, pričom medzi oboma vrstvami (51, 52) je usporiadaná vrstva (53) akt ivovateľného napúčavého prášku.SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a power cable with a shield made of wires, which is located below the outer sheath on a conductive layer produced by extrusion, and a conductive and swellable tape filler layer is provided between the conductive layer and the shielding wires. (5) The conductive and swellable strips consist of composite layers (51, 52) of nonwoven and foamed fabric, wherein the foamed fabric lies outwardly, wherein a layer (53) of activatable swellable powder is disposed between the two layers (51, 52).
Výhodou riešenia podľa vynálezu je, že v jednej výrobnej operácii je zaistené pripevnenie tieniacich drôtov (najmä tieniacich drôtov spletených do tvaru SZ) dobré vyhotovenie f tlmenia tienenia a zaistenie vodotesnosti v pozdĺžnom smere.An advantage of the solution according to the invention is that in one manufacturing operation, the securing of shielding wires (in particular shielding wires braided in the shape of SZ) is ensured by a good design of shielding damping and ensuring water-tightness in the longitudinal direction.
