    摘要: A method for monitoring deformations in a tire of a vehicle wheel, the wheel including the tire and a rim, the method including: providing the wheel with at least two magnetic-field emitters mutually disposed so as to yield a composite magnetic field having one or more space portions where at least one component of the composite magnetic field is substantially null; disposing at least one main magnetic-field sensor substantially in one of the one or more space portions; monitoring variation of the at least one component of the composite magnetic field; and correlating the variation with tire deformations. At least one of the magnetic-field emitters is disposed in contact with the tire. A system for monitoring deformations in a tire of a vehicle wheel includes the wheel, the at least two magnetic-field emitters, and the at least one main magnetic-field sensor.

    摘要: An electrical cable having at least one conductor and at least one extruded insulating coating layer. The extruded insulating coating layer includes a polymeric composition having a polyethylene grafted with at least one unsaturated carboxylic acid of general formula (I): in which: R represents H or CH3; n represents 0 or 1. The grafted polyethylene is derived from polyethylene, a radical initiator and at least one unsaturated carboxylic acid of general formula (I) in free form; and the unsaturated carboxylic acid is present in an amount of between 0.0006% and 0.25% by weight. The amount is expressed as the weight content of —COOH groups relative to the total weight of the polymeric composition.

    摘要: A cable with recyclable covering, particularly for transporting or distributing medium or high voltage energy, in which at least one covering layer is based on a thermoplastic polymer material of a propylene homopolymer or a copolymer of propylene with ethylene or an α-olefin other than propylene in mixture with a dielectric liquid. The cable possesses superior mechanical and electrical properties, including high dielectric strength, in particular enabling it to be used at high operating temperature.
