In this paper, we study the effect of insulating and non-insulating cost allocations on internal trade in a model of incomplete information. From the perspective of firm-wide profit, the allocation scheme that results in the least amount of rationing (forgone profitable trade) is the optimal one. If one thinks of internal trade as a form of cooperation, one might expect non-insulating allocatio...

This work analyzes and discusses analytically a method of controling the insulating properties of an assembly. It establishes the feasibility of utilizing gas layers within the insulating assembly separated by flexible soft seals. The volumetric thermal expansion of the main gas layers within the insulating assembly are determined taking into consideration the variation in the gas pressure due ...

The coating impedance size can reflect the aging degree of to a certain extent; therefore, measurement monitor in real time. Since is traditionally considered as an insulating medium, its value before high 108Ω or more, it difficult achieve accurate measurement, and current generated by loading voltammetry at low voltage very weak easily affected external electromagnetic interference noise, acc...

A novel strategy for manufacturing of the main insulation high voltage rotating machines is presented. The developed process based on established electrostatic powder coating equipment. Using complete automation enables precise and reproducible application homogeneous layers. Individual layers can be stacked by repetitions to achieve a desired layer thickness. This alters particle deposition in...

Under the thermal action on wood when applying a protective screen made from fire-retardant fabric, process of temperature transfer is natural. It has been proven that depending properties coating fire-proof this could lead to varying degrees heat transfer. Therefore, it becomes necessary study conditions for establishing low conductivity and mechanism inhibits wood. Given this, mathematical mo...

Room-temperature vulcanized rubber is an excellent polymer material with electrical insulation and mechanical properties, which can be used for field of high-voltage bare wire.
