Primary conductors are the veins and arteries of electrical switchgear, whether it be copper / aluminium busbar or at lower ratings covered flexible cable, without them the life blood of electricity will not flow.
All very dramatic sounding but it in essence it is a correct analogy as the equipment would not come to life without it.
To ensure our current transformers function within required parameters they need the help of correctly specified busbar.
As a guide we have included a link to Properties of HC Copper Conductors
Other parameters which need to be taken into consideration as part of the specification:
