Down conductor
| Глоссарий по архитектуре и конструкциям |
The vertical portion of an electric conductor used in a lightning protection system to provide a lightning current path from the air terminals to ground. downdraft, brit. downdraught 1. a downward current of air in a chimney or flue, often carrying smoke with it. 2. a downward current of air resulting from the passage of air across a window surface, which cools it and increases its density so that it moves downward. down-feed system 1. a piping arrangement for a heating (or air-conditioning or refrigeration) system, in which the heating (or cooling) fluid is circulated through supply mains that are above the levels of the heating (or cooling) units they serve. 2. a water distribution system in which the water distribution main is located at the top of the pressure zone; the distributionmain supplies the risers that distributes water downward to the lowest point of the zone.

Conductor, английский
- A substance which permits the flow of current.
- A wire or combination of wires not insulated from one another, suitable for carrying an electric current.
- 1. a substance or object which allows heat, electricity, light or sound to pass along it or through it 2. a tube with a groove in it along which a knife is slid to cut open a sinus
- A thick metal wire, generally of copper, extending from above the main truck downwards into the water, or in the form of a chain with long links. its use is to defend the ship from the effects of lightning, by conveying the electric fluid into the sea.
- A relatively short length of pipe driven through the unconsolidated zone of top soil as the first step in collaring a borehole. also called conductor pipe, stand pipe.
- In petroleum drilling, the piping carried through overburden to bed rock or the first string of casing placed in a borehole.
- The material through which electricity is transmitted, such as an electrical wire, or transmission or distribution line.
- A material used to transfer, or conduct, electricity, often in the form of wires.
- The material through which electricity is transmitted, such as an electrical wire,
- Us term for train staff member whose duties vary with different administrations but who is primarily responsible for train and passenger safety. often also involved with ticket inspection. in uk parlance was often referred to as the `guard` but the same term is now common.

Conductor rail, английский
- An additional rail (or rails) provided on those electric railways where power is transmitted to trains from the track. often referred to as the `third rail` or `current rail` , it is normally at positive potential and is mounted on insulators to the outside of and slightly higher than the running rails. the return of the circuit is via the running rails. the current is collected by the train through `shoes`, attached to the bogies, which slide along or under the rail. varieties of the system include top, side and bottom contact rails. top contact rails are susceptible to ice and snow contamination in cold climates and present a certain risk to persons walking on the track. for this reason, bottom contact rails are preferred for modern systems. illustrations and descriptions here. the continuity of conductor rails must be broken at junctions in the track to allow continuity of the running rails. such `gaps` may cause momentary loss of power to the train. there are cases from time to time of trains becoming `gapped` at complex junctions, i.e. they stall over a gap and have to be rescued by another train. london underground has a fourth rail (negative) for a completely insulated circuit. it is known as a four rail system.
- A rail through which dc electricity is supplied to electric trains operating on the third rail system.

- The distribution of a set of numerical data is how their values are distributed over the real numbers. it is completely characterized by the empirical distribution function. similarly, the probability distribution of a random variable is completely characterized by its probability distribution function. sometimes the word "distribution" is used as a synonym for the empirical distribution function or the probability distribution function. if two or more random variables are defined for the same experiment, they have a joint probability distribution.
