An electric cable comprising: a cable core having a radius and comprising an electric conductor and an insulating system; a first metal layer in radially outer position with respect to the cable core; and a semiconductive protecting layer between the cable core and the first metal layer. The insulating system comprises an insulating layer based on a propylene copolymer and the protecting layer is made of non-expanded material and has a thickness of from 0.5% to 3% the radius of the cable core. The cable is apt to safely operate at thermal cycles of from 20 C. to at least 90 C. (for example up to 130 C. or more), with substantially no deformation of the metal layer and of the overall cable structure.

For the purpose of improving energy efficiency or improving sound quality, there is provided a cable, a power supply tap, a battery, a printed circuit board, a LSI/IC and the like comprising a hygroscopic fiber, an inorganic ion exchanger influence fiber, a supercritical influence fiber, a composite fiber obtained by mixing two or more among the mentioned fibers, or a hygroscopic resin, an inorganic ion exchanger influence resin, a supercritical influence resin, and a composite resin obtained by mixing two or more among the mentioned resins, and a power supply method of supplying power to a device or a battery.

A cable connection (16) for a dosing module (6) for exhaust gas reduction, with a dosing module end (16b), which is designed for connection to the dosing module (6), and an end (16a) distant from the dosing module, comprising at least one electrical cable (19a, 19b) having at least one electrical conductor (28a, 28b) and a cable insulation (15a, 15b) surrounding the at least one electrical conductor (28a, 28b). The cable connection (16) is crimped in one region (26a) at the dosing module end (16b) of the cable connection (16). In the crimped region, a space (36) between the at least one electrical conductor (28a, 28b) and the cable insulation (15a, 15b) surrounding the at least one electrical conductor (28a, 28b) is filled with a silicone material (17a, 17b).

A signal cable structure includes a set of strands, an outer insulation tube and a water swellable powder. The set of strands includes a plurality of twisted pairs. The twisted pairs are enclosed to form a center portion, and each of the twisted pairs includes two wires intertwined with each other. The outer insulation tube sheaths the set of strands; an outer ring portion is surrounded outside the set of strands and formed between the outer insulation tube and the set of strands. The water swellable powder is distributed in the outer ring portion, and the center portion of the set of strands is not distributed with the water swellable powder. Thereby, a signal cable with waterproof performance is provided.

An electrical conductor comprises three or more solid segments of identical shape. In cross-section, each segment comprises two sides, which are configured for flush bearing against correspondingly opposing lateral surfaces on another segment. The cross-sectional surface through all the constituent segments of the electrical conductor is describable by a closed curve having a stepless characteristic. All the constituent segments of the electrical conductor are stranded in combination.

Embodiments of a telecommunications equipment enclosure are provided herein. The telecommunications enclosure includes a first portion having a first sealing surface and a second portion having a second sealing surface. The first portion and the second portion define an internal cavity when the first portion and the second portion are in a closed configuration. The telecommunications enclosure also includes a first gasket mounted to either the first sealing surface or the second sealing surface and superabsorbent polymer (SAP) located on at least one of the first portion and the second portion for restricting ingress of water into the internal cavity
