Description

DESCRIZIONE del modello di utilità avente per titolo: DESCRIPTION of the utility model having as title:

LA GIUNZIONE PER CAVI ELETTRICI DI BASSA TENSIONE, IN LINEA O IN DERIVAZIONE, PER IMPIEGO INTERRATO, AEREO O SOMMERSO, CON ISOLAMENTO IN GEL E CON • SEPARATORE FERMACAVO (ved.fig. 1) VUOLE EVITARE LO SCORRIMENTO DEI CAVI ALL’INTERNO DELLA GIUNZIONE E MIGLIORARE LA SEPARAZIONE DELLE CONNESSIONI. NEI GIUNTI IN GEL, UNA FORZA, APPLICATA SULLA SCATOLA DI PROTEZIONE DELLA GIUNZIONE PARALLELAMENTE ALL’ASSE DEL CAVO, PUÒ’ PROVOCARE LA TRASLAZIONE DELLA SCATOLA RISPETTO ALLA GIUNZIONE. THE JUNCTION FOR LOW VOLTAGE ELECTRIC CABLES, IN LINE OR BY SHAFT, FOR UNDERGROUND, PLANE OR SUBMERSIBLE USE, WITH GEL INSULATION AND WITH • CABLE SEPARATOR (see fig. 1) WANTS TO AVOID THE SLIDING OF THE CABLES INSIDE THE JUNCTION AND IMPROVE CONNECTION SEPARATION. IN THE GEL JOINTS, A FORCE, APPLIED TO THE JUNCTION PROTECTION BOX PARALLEL TO THE CABLE AXIS, MAY CAUSE THE BOX TO MOVE WITH RESPECT TO THE JOINT.

INFATTI, AFFINCHÉ’ LA GIUNZIONE SIA RI ACCESSIBILE, IL GEL NON DEVE INDURIRE. QUINDI, NON AVENDO LA CAPACITA’ MECCANICA DI IMPRIGIONARE SOLIDAMENTE LA GIUNZIONE NEL CONTENITORE DI PROTEZIONE; RENDEREBBE POSSIBILE LA TRASLAZIONE DELLA GIUNZIONE NELLA SCATOLA ESPONENDO LA GIUNZIONE ELETTRICA AGLI AGENTI ATMOSFERICI ED AI CONTATTI CON L’ESTERNO SENZA ASSICURARE PIU’ L’ISOLAMENTO DELLE PARTI ATTIVE. IN FACT, FOR THE JOINT TO BE ACCESSIBLE, THE GEL MUST NOT HARDEN. THEREFORE, NOT HAVING THE MECHANICAL CAPACITY TO SOLIDLY IMPRISON THE JUNCTION IN THE PROTECTIVE CONTAINER; IT WOULD MAKE POSSIBLE THE TRANSLATION OF THE JOINT IN THE BOX BY EXPOSING THE ELECTRIC JOINT TO THE ATMOSPHERIC AGENTS AND TO CONTACTS WITH THE OUTSIDE WITHOUT ENSURING THE INSULATION OF THE ACTIVE PARTS.

UN SEPARATORE SOLIDALE ALLA SCATOLA DI PROTEZIONE DELLA GIUNZIONE, INTERPONENDOSI FRA LE FASI PER TUTTA LA LUNGHEZZA DELLA ZONA SGUAINATA, IMPEDISCE LA TRASLAZIONE DEL CAVO ALL’INTERNO DEL GIUNTO ED ASSICURA UN MIGLIORE ISOLAMENTO FRA I CONDUTTORI SGUAINATI. A SOLID SEPARATOR TO THE JUNCTION PROTECTION BOX, INTERPOSING BETWEEN THE PHASES FOR THE ENTIRE LENGTH OF THE DRAWN AREA, PREVENTS THE TRANSLATION OF THE CABLE INSIDE THE JOINT AND ENSURES BETTER INSULATION BETWEEN THE UNDRAWN CONDUCTORS.

Claims

CLAIMS 1) - THE GEL JOINT WITH SEPARATOR CAN HAVE ANY SHAPE SUITABLE FOR MAKING BOTH IN-LINE AND DERIVATION JOINTS, BOTH TANGENT AND "T" (see fig. 2) 2) - THE SEPARATOR HAS THE FUNCTION OF LOCKING THE JOINT AND SEPARATION OF THE ACTIVE PARTS BARE FOR THE REALIZATION OF THE JOINT. 3) - THE SEPARATOR MAY HAVE SLOTS FOR THE PASSAGE OF THE DERIVATIVE CABLES. 4) - THE SEPARATOR CAN BE MADE IN ONE PIECE WITH THE MOLD OF THE JOINT SHELL OR IT CAN BE MADE SEPARATELY AND SUBSEQUENTLY ASSEMBLED AND LOCKED, WITH SUITABLE SYSTEMS, IN THE SHELL ITSELF. 5) - THE SEPARATOR CAN TAKE ANY SHAPE PROVIDED THAT IT IS SUITABLE FOR THE PURPOSE OF SEPARATING THE CABLES AND AVOID THEIR SLIDING IN THE JUNCTION. 6) - THE SEPARATOR CAN BE MADE IN TWO PIECES, NOT NECESSARILY SYMMETRICAL, ONE IN THE BASE AND THE OTHER IN THE COVER OF THE JOINT SHELL. 7) - THE SEPARATOR CAN BE MADE IN ONE PIECE WITH THE BASE OR WITH THE COVER OF THE JOINT SHELL. 8) - THE SEPARATOR CAN BE MADE IN SEVERAL PIECES, PRINTED WITH THE SHELL OR SEPARATELY. 9) - THE SEPARATOR CAN BE FIXED OR REMOVABLE.
