Electrical ballast - Wikipedia

An electrical ballast is a device placed in series with a load to limit the amount of current in an electrical circuit.. A familiar and widely used example is the inductive ballast used in fluorescent lamps to limit the current through the tube, which would otherwise rise to a destructive level due to the negative differential resistance of the tube's voltage-current characteristic.

Fluorescent Ballasts - Electrical 101

Fluorescent tubes have two common shapes, straight and u-shaped. The most common types are T12, T8, and T5. The T stands for tubular and the number indicates the diameter in 1/8 of an inch. Lamp diameter is determined by ballast type. A fixture with a T12 ballast must use a T12 bulb. A fixture with a T8 ballast must use a T8 bulb, etc.

Survey of Railway Ballast Selection and Aspects of ...

Ballast is the main structural part of railroad where the sleepers (or ties in US) are laid. Its main function is to transfer the loads coming from the super structure to the subgrade without failure and providing good drainage.

Failures of Railway Concrete Sleepers During …

Sleeper, after rail, is the most important component of track superstructure in conventional track. Keeping track geometry, bearing loads acted from rail and transferring to the ballast is the main duty of sleeper. Their quality conditions have considerable influence on geometry quality. Moreover, track maintenance costs affected by this element due to their higher number.

The current study highlights the influence of particle breakage on the resilient modulus of latite ballast (commonly used in railway track in New South Wales, Australia). Aggregate degradation is represented by the ballast breakage index (BBI). Laboratory test results indicate that the BBI has a profound influence on the resilient modulus of ballast. The resilient modulus increases with BBI ...

Tamping machine - Wikipedia

A tamping machine or ballast tamper is a machine used to pack (or tamp) the track ballast under railway tracks to make the tracks more durable. Prior to the introduction of mechanical tampers, this task was done by manual labour with the help of beaters. As well as being faster, more accurate, more efficient and less labour-intensive, tamping machines are essential for the use of concrete ...
