About Insulated Glass Units | Vitro Residential Glass glass units, or IGUs, are designed to keep homes warmer in the winter and cooler in the summer. An insulating glass unit commonly consists of two (sometimes more) panes of glass separated by a spacer material and sealed together at the edge. The insulating airspace is filled with air or a noble gas, such as argon or krypton inside.
Gas-Insulated Switchgear | High Voltage Experts Insulated Switchgears and substations (GIS) were designed to overcome the limitations of air and oil insulated power systems. GIS requires only 10% of the clearance specified for phase to phase and phase to ground for all equipment; and is widely c onsidered to be safer, more reliable and requires less maintenance than air or oil insulated ...
