Busbar elements
Busbar trunking unit BTU.
Busbar trunking units / busbar elements can take various geometric shapes, such
as, for example
-
Straight length: straight busbar element
-
Change directions
-
T-elements
Busbar trunking run / BTR
If a busbar trunking system BTS consists of connected busbar trunking units, one
speaks of a busbar trunking run.
Busbar trunking system BTS
(BTS: busbar trunking system). A bus trunking system BTS is used according to
EN 61439-6 as a self-contained switchgear combination for distributing and
controlling electrical energy
-
for all types of loads,
-
for industrial, commercial or similar applications.
According to EN 61439-6, a busbar trunking system BTS is a self-contained
switchgear combination in the form of a conductor system. The conductor
system contains busbars in a duct, a trough or a similar housing. The busbars are
kept apart by insulating material.
The busbar trunking system BTS may consist of many mechanical and electrical
resources including, for example:
-
Busbar trunking units (busbar elements) without plug-in,
-
Busbar trunking units (busbar elements) with plug-in,
-
Tap-off units,
-
Outgoing and adaptation units...
As a self-contained switchgear combination, the busbar trunking system BTS is
encased so that a defined degree of protection is achieved.
The EN 61439-6 standard must be applied for busbar trunking systems BTS
