cable tray

For example, see cable tray movement in a German test.

However they managed it, three of the largest were now picking their way along the cable tray, heading in this direction.

For example, different sizes of cable tray used within one run can be connected with reducers.

Walls and ceilings may have to support a heavy cable tray system or busbars.

Regular housecleaning is important for safety, as cable trays are often installed in hard to reach places.

Ferrous cable trays expand with the increasing heat from accidental fire.

In industrial applications cables may be laid in cable trays.

Cable trays are used in industrial areas where many insulated cables are run together.

Pathway fill is provided for cable tray.

Data cabling is typically routed through overhead cable trays in modern data centers.

For example, when long runs of aluminium are pulled through conduit and cable trays, they can stretch and neck-down.

Hemyc, which is produced in blanket form, is often wrapped around cable trays or junction boxes and stitched together.

In the electrical wiring of buildings, a cable tray system is used to support insulated electric cables used for power distribution and communication.

Lighter cable trays are more appropriate in situations where a great number of small cables are used, such as for telephone or computer network cables.

Various clamping, supporting and splicing accessories are used with the cable tray to provide a complete functional tray system.

Common cable trays are made of galvanized steel, stainless steel, aluminum, or glass-fiber reinforced plastic.

Combustible cable jackets may catch on fire and cable fires can thus spread along a cable tray within a structure.

Electrical power cables are often installed in raceways, including electrical conduit and cable trays, which may contain one or more conductors.

Providing fireproofing for cables, cable trays, or electrical conduit, is meant to keep cables operational during a specified fire exposure and time.

Structural steel pipe racks typically support pipes, power cables and instrument cable trays in petrochemical, chemical and power plants.

Pipe racks carry process and utility piping and may also include instrument and cable trays as well as equipment mounted over all of these.

Since power distribution often requires large numbers of electrical cables, special measures for fire resistance of cables and cable trays may be also specified by regulations.
