A sensored insulation plug for a separable connector in a MV/HV power distribution network of a national grid, operable to sense the MV/HV elevated voltage. The sensored insulation plug includes a plug body formed by a solidified insulating material, a contact piece, and a discrete coupling capacitor embedded in the insulating material and operable to harvest energy from the elevated voltage of the contact piece and optionally operable to superimpose a communication voltage signal over the elevated voltage. The sensored insulation plug further includes an integrated sensing capacitor, operable as a high-voltage capacitor in a sensing voltage divider for sensing the elevated voltage. The sensing capacitor comprises a high-voltage electrode comprising the coupling electrode and the contact piece, a tubular sensing electrode, and a dielectric comprising a portion of the insulating material.

The invention relates to a method for producing a hollow electrical insulator having the following steps:—providing a core,—winding first wound layers (2) of a first fiber element onto the core,—winding second wound layers (7) of a second fiber element (8) onto an end region (10) of the core, wherein—the first wound layers (2) comprise turns of the first fiber element which include a first winding angle with a main direction of extension (R) of the core,—the second wound layers (7) comprise turns (18) of the second fiber element (8) which include a second winding angle (α2) with the main direction of extension (R) of the core, which second winding angle is larger than the first winding angle, and—an inner region (11) of the core remains free of second wound layers (7). The invention also relates to a hollow electrical insulator and the use thereof.

Embodiments of the present invention generally relate to a novel system, device, and methods for providing an isolator for components and instrumentation to isolate vibrations, shock, static or quasi-static loads, thermal loads, and electrical currents. The novel isolator has an asymmetrical shape, experiences uniform motion under quasi-static loading, and reduces the effective modal mass across a range of frequencies. The novel isolator outperforms conventional vibration isolators in terms of cost, schedule (manufacturing time and lead time), heat dissipation, and performance.

A method for manufacturing a grommet, which is fixed to a wire harness W inserted into an opening portion of a panel P and which is fitted and attached to the opening portion to thereby support the wire harness W on the panel P. The grommet includes peripheral walls that surrounds the wire harness W to form a sound shield space S around the wire harness W, and a soundproof wall that is formed in the sound shield space S so as to cross a longitudinal direction of the wire harness W. The soundproof wall is designed by use of an expression of TL=20 log(p×f)−42.5 where TL designates transmission loss of the soundproof wall, ρ designates surface density of the soundproof wall, and f designates a frequency.
