Description
Oppfinnelsen angår en kabel med beskyttelse mot gnagere. Fra britisk patentsøknad nr. 20 26 191 A, er det kjent en kabel hvor glassfiberbånd er viklet rundt en indre kappe av plast som beskyttelse mot gnagere. Utenfor disse er det anbragt en ytre kappe av plast. I tysk DE-OS nr. 31 16 964 vises det til en kabel omviklet med metallband som beskyttelse mot gnagere. The invention relates to a cable with protection against rodents. From British patent application no. 20 26 191 A, a cable is known in which glass fiber tape is wrapped around an inner sheath of plastic as protection against rodents. Outside these, an outer sheath made of plastic is placed. German DE-OS No. 31 16 964 refers to a cable wrapped with metal tape as protection against rodents.
Hensikten med oppfinnelsen er å tilveiebringe et gnagerskade-beskyttende lag som kan tilpasses alle typer kabler, og som er lett å produsere. The purpose of the invention is to provide a rodent damage protective layer which can be adapted to all types of cables, and which is easy to produce.
De vesentligste særtrekk ved oppfinnelsen er definert i kravene. The most significant features of the invention are defined in the claims.
Det er å foretrekke at beskyttelseslag mot gnagerskader er produsert ved ekstrudering. Kabelen er ikke påvirket av høy-spenning, lynnedslag osv. når kabelkappen i tillegg til kabelkjernen er fri for metall. Beskyttelseslaget mot gnagerskade har ingen negativ effekt på tetning av kabelen mot langsgående vannpassasje. It is preferable that the protective layer against rodent damage is produced by extrusion. The cable is not affected by high voltage, lightning strikes etc. when the cable jacket as well as the cable core is free of metal. The protective layer against rodent damage has no negative effect on sealing the cable against longitudinal water passage.
Ovenfor nevnte og andre formål og særtrekk ved den foreliggende oppfinnelse vil klart fremgå av den etter-følgende detaljerte beskrivelse av to utførelser av oppfinnelsen sett i sammenheng med figurene. The above-mentioned and other purposes and special features of the present invention will be clear from the following detailed description of two embodiments of the invention seen in connection with the figures.
Fig. 1 viser en kabel med en kabelkjerne som har et sentralt strekkelement bestående av en strekkresisterende kjerne 1, et fyll-lag 2 rundt kjerne 1, samt et utenpå-liggende svellebånd 3 i plast. Fig. 1 shows a cable with a cable core which has a central tensile element consisting of a tensile-resistant core 1, a filling layer 2 around the core 1, and a plastic swelling band 3 on the outside.
Åtte optiske bølgeledere 4 er plassert rundt det sentrale strekk-element. Rundt disse finnes et annet svellebånd 5 av plast som tetter kabelkjernen mot utsiden. Rundt dette er det et indre lag 6 av plast, deretter et beskyttelseslag 8 mot gnagerskader og ytterst en kappe 7 av plast. Eight optical waveguides 4 are placed around the central tensile element. Around these there is another swelling band 5 made of plastic which seals the cable core to the outside. Around this there is an inner layer 6 of plastic, then a protective layer 8 against rodent damage and at the outer end a sheath 7 of plastic.
I de foretrukne konstruksjoner av kabelen er den strekkresisterende kjernen 1 laget av plastmateriale med glassfiber-forsterkning og fyll-laget av polyetylen. De optiske bølgeledere 4 er løse enkeltfiber-rør eller mul ti fiber-rør. I en viss grad kan disse erstattes med blindrør. Svei 1ebåndene av plast 3, 5 sørger for tetning mot langsgående vannpassasje. Ytre kappe av plast 7 er laget av polyesterelastomer eller f1uorpolymer. In the preferred constructions of the cable, the tensile-resistant core 1 is made of plastic material with glass fiber reinforcement and the filling is made of polyethylene. The optical waveguides 4 are loose single fiber tubes or multi fiber tubes. To a certain extent, these can be replaced with blind pipes. The plastic welding strips 3, 5 provide a seal against longitudinal water passage. The outer sheath of plastic 7 is made of polyester elastomer or fluoropolymer.
Beskyttelseslaget 8 består av plastmateriale på en silikon-, polyuretan-, polyolefincopolymer-basis med glasspartikl er innsatt. Glasspartikl ene er tilført i form av hule mikrokuler av glass, glasspulver, glassfliser og/eller korte glassfibre med en lengde av flere millimeter. Dette laget 8 er produsert ved ekstrudering. Som en ekstra beskyttelse kan man benytte en sammensatt konstruksjon innenfor eller utenfor beskyttelseslag 8 som forklart i forbindelse med figur 2. The protective layer 8 consists of plastic material on a silicone, polyurethane, polyolefin copolymer basis with glass particles inserted. Glass particles are supplied in the form of hollow glass microspheres, glass powder, glass tiles and/or short glass fibers with a length of several millimeters. This layer 8 is produced by extrusion. As an additional protection, a composite construction can be used inside or outside protective layer 8 as explained in connection with Figure 2.
Ved en annen utførelse av oppfinnelsen består beskyttelseslaget 9 av et ekstrudert plastbelegg påført glasspartikl er. Dette belegget kan kombineres med den sammensatte konstruksjonen, men det skal da være utenpå denne. In another embodiment of the invention, the protective layer 9 consists of an extruded plastic coating applied with glass particles. This covering can be combined with the composite construction, but it must then be outside this.
Forskjellen mellom kabelen i fig. 2 og den i fig. 1 ligger i konstruksjonen for beskyttelse mot gnagere. Referansenummere for kabelkjernen, indre kappe 6 og ytre kappe 7 er brukt uforandret i tillegg til de relevante beskrivelsene. Beskyttelse mot gnagere består av en sammensatt konstruksjon av vevet bånd 10, med glasstrådb-ånd 11, og et lag eller hinne av varmeherdende klebemiddel 12. Båndet 10 består av glassfiber forgarn og vevde glasstråder. Dette glassbåndet er enten satt på langs eller viklet rundt den indre plastkappe 6. Over dette er det tilsatt en hinne eller lag av termoplastisk klebemiddel 12. Det siste sørger for den sammensatte konstruksjo-nens interne sammenheng. Ytre lag av den sammensatte konstruksjon er formet ved vikling av glass-fi 1ament bånd 11 slik at den overlappes. Tykkelsen til den sammensatte konstruksjonen skal være minst en millimeter. Det beskyttende lag mot gnageskader 9 som består av plast påført med glasspartikl er er anbragt på glassfi 1ament-bandet 11 og tjener som et bindende ledd. The difference between the cable in fig. 2 and the one in fig. 1 is in the construction for protection against rodents. Reference numbers for the cable core, inner jacket 6 and outer jacket 7 are used unchanged in addition to the relevant descriptions. Protection against rodents consists of a composite construction of woven band 10, with glass fiber band 11, and a layer or film of heat-setting adhesive 12. The band 10 consists of fiberglass yarn and woven glass threads. This glass band is either placed lengthwise or wrapped around the inner plastic sheath 6. Above this is added a film or layer of thermoplastic adhesive 12. The latter ensures the internal coherence of the composite construction. The outer layer of the composite construction is formed by winding the glass filament band 11 so that it overlaps. The thickness of the composite construction must be at least one millimeter. The protective layer against abrasion damage 9, which consists of plastic applied with glass particles, is placed on the glass fiber band 11 and serves as a binding link.
Denne oppfinnelsen er også tilpasset elektriske kabler. Avhengig av den respektive kabelkjernen kan man klare seg uten indre plastkappe 6. Kabelens strekkstyrke kan forbedres eller forsterkes ved å forsyne den ytre kappe 7 med ekstra styrke-elementer. This invention is also adapted to electric cables. Depending on the respective cable core, one can manage without an inner plastic sheath 6. The cable's tensile strength can be improved or reinforced by supplying the outer sheath 7 with extra strength elements.
Ovenstående detaljerte beskrivelse av noen utførel-seseksempler av foreliggende oppfinnelse skal bare betraktes som eksempler og må ikke oppfattes som begrens-ninger av beskyttelsens omfang. The above detailed description of some embodiments of the present invention should only be considered as examples and must not be understood as limitations of the scope of the protection.
