Abstract: There is disclosed a coupling device for operations on live elements to attain equipotential conditions. The device comprises two conductive jaws connected to a preferably nonconductive handle. The jaws are adapted to be switched between a closed configuration, in which they are in mutual contact and surround an area adapted to receive a live element, and an open configuration in which the contact portions of the two jaws are spaced apart from each other. The two jaws have respective entry tapering portions adjacent to the contact portions and mutually converging to cause the contact portions to move apart from each other when the live element is pressed against the entry tapering portions, thereby causing the jaws to switch from the closed configuration to the open configuration against the action of an elastic member.

Abstract: Headgear for a shielding garment for operating on components exposed to high voltage, or for operating at a safe distance proximate to high voltage parts, or for activities involving exposure to high electric and/or electromagnetic fields at any frequency and voltage is disclosed. The headgear comprises a cover element which is configured to cover the head of an operator and has an opening at least at an upper portion of the operator's face. The headgear further comprises a transparent face shield made of an electrically conductive fabric. The face shield is removably coupled to the cover element to close the opening and is electrically connected to the shielding garment. The fabric has a density ranging from 25 to 40 g/m2 and comprises a plurality of yarns having a yarn count ranging from 10 to 30 deniers, and each comprising a respective core externally covered with a coating made of a conductive metal.

Abstract: The present invention relates to an electrically conductive textile yarn for production of protective garments, comprising a first element which is made electrically conductive by means of a layer of silver, and a second element which is different from the said first element, and is provided with good resistance to fire; the first element can be in the form of filaments or fibers. The present invention also relates to a garment produced by means of a yarn of this type and to a method for production of the yarn itself.

Abstract: The present invention relates to integral protective overalls for operations on uncovered high-voltage cables, comprising a first electrically conductive layer whose surface area is substantially equal to the surface area of the overalls and that is obtained from a polymer fibre covered with silver. The overalls of the present invention can also include a second layer connected to the first layer in a stable manner.
