3 Construction and characteristics
3.1 Characteristics of the busbar system
-
Compliance with the IEC 61439-1 and 61439-6 international standards, as
well as all European and national standards derived from them; CE-marking.
-
Voltages up to 1000 V, frequency 50/60 Hz
-
Protection type IP55 / IP65 or IP68 (cast resin system, only for energy
transport), also feasible combined within one busbar run
-
The inner conductor of the busbar elements is made either from a tinned
aluminium alloy or from 99.9% pure ETP-copper conforming to EN 13601
-
Housing made from 1.5 mm galvanised steel or an aluminium housing,
painted in RAL 7035 (special colours possible)
-
Housing is used as PE protective conductor
-
Heat is dissipated by the surface of the housing. The temperature rise of the
housing remains below 55 ° even at the rated current, irrespective of the
installation position and orientation
-
Ambient temperature: min. -5 °C, max. 35 °C, 24-hour average 35 °C
-
System components are free of silicones and halogens
Flexibility and expandability
-
Horizontal and vertical mounting is possible, with no reduction in nominal
capability (with N conductor in bottom position for horizontal mounting and
flat installation position)
-
Busbar elements available in various geometric shapes for changing direction
-
Straight busbar elements available with or without plug-in in lengths up to
3 m
-
Straight busbar elements available in selectable lengths 410 - 3000 mm
-
Individual busbar elements can be removed without having to remove the
adjacent busbar elements (protection type IP55 / IP65).
-
The joint block in the connection joints of the busbar elements enables
efficient assembly and later checking or tightening of the torque (protection
type IP55 / IP65).
-
State-of-the-art single bolt clamps with torque indicated by the shear-off
bolt.
-
Torque with the joint block in the connection joints of the busbar
elements: approx. 60 Nm
-
Feeder units for transformers, terminals and cable feeders
Tap-off units for plug-in or connection joints
-
Tap-off units can also be installed later by electrical specialists
-
Tap-off units available with HRC fused switch disconnector, or with circuit
breakers (MCCB)
-
Tap-off units up to 630 A for plug-in on straight busbar elements can be fitted
while voltage is applied (taking account of EN 50110 and national regulations)
-
Tap-off units 250 A - 1250 A available for connection joints with a special
joint block
