Bars of double body systems for the same phase have balanced at each
connection joint to ensure equal current distribution. Special components for
phase compensation are not permitted.
Heat is dissipated by the housing. The temperature rise of the housing at the
particular rated current must not exceed 55 °, regardless of the installation
position.
The busbar system must ensure protection type IP55 / IP65. It must be possible
to use the same busbar system to implement protection type IP68 for energy
transport, even within one busbar run. Busbar elements with protection type IP68
are also built using sandwich construction and are then filled with casting resin.
The manufacturer of the busbar system must maintain and demonstrate a
certified quality management system conforming to EN ISO 9001.
The following qualifications for the entire system must be verified by certificates
or declarations of conformity:
-
IEC / EN 61439-1 and -6
-
Fire protection, tested to EN 1366-3
-
Silicone and halogen free
-
Sprinkler test
-
Functional endurance (on demand)
Special, additional properties of system components must be positively verified.
