A padmount or pad-mounted transformer is a ground-mounted electric power distribution transformer in a locked steel cabinet mounted on a concrete pad. Since all energized connection points are securely enclosed in a grounded metal housing, a padmount transformer can be installed in places that do not have room for a fenced enclosure.
A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel- reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving ( see below ).
A section through Zibold's dew condenser. (a) is a truncated cone of beach pebbles 20 metres (66 ft) in diameter at the base and 8 metres (26 ft) in diameter at the top. (b) is a concrete bowl; a pipe (not shown) leads away from the base of the bowl to a collecting point. (c) is ground level and (d) is the natural limestone base. [11]

Initial costs are greater, and they are unsuitable for change of gauge, unless this is already taken into account. Concrete sleepers are up to 300 pounds (136.1 kg) heavier than their wooden counterparts. As a result, larger sized ballast is required to both support and hold in place the sleepers on the roadbed.
Hush kit for the Pratt and Whitney JT8D-1 through -17 engines Two JT4As installed on a KLM DC-8. A hush kit is an aerodynamic device used to help reduce the noise produced by older aircraft jet engines. These devices are typically installed on older turbojet and low-bypass turbofan engines, as they are much louder than later high-bypass ...
