Abstract

An electric cable for high voltage applications, such as loads for fluorescent arc lamps, are built with an earthing layer comprising a sleeve of conductive mesh (II) between coaxial layers of electrical insulating material (I) and a protective sheath (III). Specifically claimed are leads where (I) is of polyethylene, (II) of copper and (III) of PVC. Lighter, in mass and opt. colour, and more flexible than conventional leads with lead sheathing, also cheaper and less hazardous to mfr. or joint. Pref. the polyethylene based insulation incorporates a fire-retardant, an UV-stabiliser and an antioxidant system.

Description

L'invention a pour objet un câble électrique souple pour haute-tension. The invention relates to a flexible electric cable for high voltage.

Ce type de câble électrique haute-tension s 'applique notamment à 1 ' alimentation électrique des enseignes lumineuses. This type of high-voltage electric cable applies in particular to the electrical supply of illuminated signs.

Ces enseignes lumineuses pouvant être des tubes fluorescents, le câble selon l'invention est destiné à relier lesdits tubes de l'enseigne au transformateur et à relier les tubes entre eux. These light signs can be fluorescent tubes, the cable according to the invention is intended to connect said tubes of the sign to the transformer and to connect the tubes together.

Les câbles actuels présentent de nombreux inconvénients. Current cables have many drawbacks.

Les câbles actuels sont composés d'une âme en cuivre, d'une première gaine isolante en polyéthylène, d'une seconde gaine en vinyl et enfin d'une gaine de plomb. Current cables are composed of a copper core, a first polyethylene insulating sheath, a second vinyl sheath and finally a lead sheath.

Les câbles actuels pourvus d'une gaine en plomb sont donc très lourds, d'où l'existence d ' une grande difficulté dans la manutention, la pose, lorsque l'utilisateur est sur une échelle ou sur un échafaudage pour poser le câble. Current cables provided with a lead sheath are therefore very heavy, hence the existence of a great difficulty in handling, laying, when the user is on a ladder or on a scaffolding to lay the cable.

Le câble actuel est cassant à la flexion, lors de la mise en place. The current cable is brittle when flexed during installation.

Le câble est d'un coût élevé puisque le plomb est onéreux. Cable is expensive because lead is expensive.

Le câble, du fait de sa gaine de plomb, est de couleur foncée, donc il se voit dans l'enseigne. The cable, because of its lead sheath, is dark in color, so it can be seen in the sign.

Enfin, il y a un gaspillage important en ce qui concerne les chutes de plomb qui sont souvent récupérées et revendues directement par les personnes chargées de la pose. Finally, there is a significant waste with regard to lead scraps which are often recovered and sold directly by the people in charge of the installation.

I1 existe donc un coulage de matière. I1 therefore exists a material flow.

L'invention évite tous ces inconvénients. The invention avoids all these drawbacks.

Le diamètre du câble, selon l'invention, est plus petit, le poids du câble est diminué d'un tiers environ. The diameter of the cable according to the invention is smaller, the weight of the cable is reduced by about a third.

Le câble est souple et la gaine extérieure peut être de différentes couleurs pour pouvoir être facilement dissimulée. The cable is flexible and the outer sheath can be of different colors so that it can be easily hidden.

Le coût de fabrication est réduit d'environ 50 % par rap port -au cable actuel. The manufacturing cost is reduced by around 50% compared to the current cable port.

Il n'y a plus de chute de matière, puisque la gaine de plomb est supprimée. There is no longer a drop of material, since the lead sheath is removed.

La tresse en cuivre est facilement raccordable sans soudure, ni collier.  The copper braid is easily connectable without welding or collar.

Le câble électrique pour haute-tension, selon l'invention, est composé d'une âme en cuivre, formée de brins de cuivre, d'une première gaine isolante, d'une gaine tressée faisant office de masse,. d'une gaine de protection mécanique. The electric cable for high-voltage, according to the invention, is composed of a copper core, formed of copper strands, of a first insulating sheath, of a braided sheath acting as ground. a mechanical protection sheath.

L'âme en cuivre est formée d'une trentaine de brins de cuivre de 0,2 mm. The copper core is formed by around thirty 0.2 mm copper strands.

La gaine isolante peut être en polyéthylène plein qui enrobe complètement 1 ' âme en cuivre. Cette gaine est auto extinguible et résiste aux ultra-violets. The insulating sheath can be made of solid polyethylene which completely envelops the copper core. This sheath is self-extinguishing and resists ultraviolet.

La gaine faisant office de masse peut être une tresse en cuivre. The sheath acting as a mass can be a copper braid.

Enfin, la gaine de protection mécanique peut être, par exemple, en chlorure de polyvinyl. Cette gaine est auto extinguible et résiste aux ultra-violets. Finally, the mechanical protection sheath can be, for example, made of polyvinyl chloride. This sheath is self-extinguishing and resists ultraviolet.

Les dessins ci-joints donnés à titre d'exemple indicatif et non limitatif permettront aisément de comprendre l'invention. The attached drawings given by way of indicative and non-limiting example will easily make it possible to understand the invention.

Ils représentent un mode de réalisation préféré selon l'invention.They represent a preferred embodiment according to the invention.

La figure 1 est une vue du câble actuel. Figure 1 is a view of the current cable.

La figure 2 est une vue du câble selon l'invention. Figure 2 is a view of the cable according to the invention.

Le câble actuel représenté dans la figure 1 est composé d'une âme 1, d'une première gaine isolante 2, d'une seconde gaine de protection en vinyl 3 et d'une gaine pour faire office de masse et de gaine de protection en plomb 4. The current cable shown in Figure 1 is composed of a core 1, a first insulating sheath 2, a second protective vinyl sheath 3 and a sheath to act as a ground and protective sheath in lead 4.

Le câble selon l'invention, représenté dans la figure 2, est composé d'une âme en cuivre 5, d'une gaine isolante en polyéthylène 6 qui enroble complètement l'âme 5, d'une tresse faisant office de masse 7 en cuivre et enfin d'une gaine de protection mécanique 8, par exemple en chlorure de polyvinyl. The cable according to the invention, represented in FIG. 2, is composed of a copper core 5, of an insulating polyethylene sheath 6 which completely covers the core 5, of a braid acting as a mass 7 of copper and finally a mechanical protection sheath 8, for example made of polyvinyl chloride.

La souplesse du câble, selon l'invention, sa facilité de mise en place et de branchement permettent aisément de comprendre l'intérêt commercial et technique qu'il peut apporter aux installateurs de matériel électrique et notamment d'enseignes lumineuses. The flexibility of the cable according to the invention, its ease of installation and connection make it easy to understand the commercial and technical advantage that it can bring to installers of electrical equipment and in particular of illuminated signs.

La gaine extérieure 8, qui a pour fonction de protéger mécaniquement le câble, peut être en chlorure de polyvinyl. The outer sheath 8, which has the function of mechanically protecting the cable, can be made of polyvinyl chloride.

La gaine isolante 2 qui enrobe l'âme 5 du câble peut être en polyéthylène avec, un composant auto extinguible, un composant permettant de résister aux ultra-violets et un anti oxygène.  The insulating sheath 2 which coats the core 5 of the cable can be made of polyethylene with a self-extinguishing component, a component making it possible to resist ultra-violet rays and an anti-oxygen.
