Diamond dotted paper - Hitachi ABB Power Grids from insulation press paper and partially coated with epoxy resin on one or both sides and dried. The advantage with partially coated insulation press paper lies in the internal strengthening of the coil from adhesion to the conductor; this provides passage for quick evacuation of air and moisture during the drying process.
Density of SF6 Measurement: Gas Density Indicator GDI-100-D decades, the transmission and distribution (T&D) sector has relied on WIKA's analog GDI-100 gas density indicators to detect leaks and maintain proper gas pressure. Hermetically sealed, robust, and temperature-compensated, this device remains the go-to gauge for monitoring SF 6 gas in closed-tank electrical switchgear. However, there are certain capabilities that only a digital instrument can offer.
