摘要： A cable for use in a predetermined voltage class, has a conductor; an insulating layer surrounding the conductor, the insulating layer having a thickness selected to provide a predetermined electrical stress when the cable is operated at a nominal voltage in said predetermined voltage class; and a protective element around the conductor having a thickness and mechanical properties selected to provide a predetermined impact resistance capability, the protective element having at least one expanded polymeric layer. The insulating layer thickness and the protective element thickness are selected in combination to minimize the overall cable weight while preventing a detectable insulating layer damage upon impact of 50 J energy. A method for designing a cable is also disclosed.

摘要： A process for manufacturing an electric cable. In particular, the process includes the steps of: a) feeding a conductor at a predetermined feeding speed; b) extruding a thermoplastic insulating layer in a radially outer position with respect to the conductor; c) cooling the extruded insulating layer at a temperature not higher than 70° C.; and d) forming a circumferentially closed metallic screen around the extruded insulating layer. The process is carried out continuously, i.e., the time occurring between the end of the cooling step and the beginning of the screen forming step is inversely proportional to the feeding speed of the conductor.

摘要： A system for carrying electrical energy in connections in underground cables. In particular, it relates to a method of laying cables and a trench filler having a low thermal resistivity, used for laying underground cables for carrying electrical energy. More particularly, it relates to the use of an inert filler to be disposed in an area around the cables or the parts of the system, such as joints, which are disposed underground. The method of laying cables disposed in a trench includes: removing the original soil to prepare the trench; disposing a first layer of a first composition in the trench; disposing the cables on top of the first layer; disposing a second layer of the first composition on top of the cables; disposing a third layer on top of the second layer formed by a second composition to fill the trench. The first composition comprises: 60-90% by weight of crushed sand; 4-15% by weight of silt; 2-12% by weight of cement; and 4-15% by weight of water.

摘要： A method and system for transporting electric power in a link and for the analysis of the status of an electric power transmission link and the relevant current rating capability control. The method includes dividing the link into a predetermined number of segments, each segment having an associated prediction model and at least two associated temperature sensors. Upon receiving sensor values, an expected operating condition in one of the segments is determined based on the sensor value and the electric current value. Next, an actual operating condition in the segment is determined and compared with the expected operating condition. If there is a difference between the conditions, a second predetermined prediction model is associated with the segment.
