Generally speaking, with busbar supports being used within live systems, they are often handling higher temperatures. In line with the limits set out in IEC 61439, insulating components in contact with conductors may be required to continuously operate at an average of 140 °C (Maximum 145 °C). Termate’s glass-reinforced polyamide busbar supports meet this requirement, the material for them being assigned thermal class F established using methods similar to IEC 60085. Busbar supports installed in enclosures are not subjected to weathering extremes or significant variations in humidity or moisture, so there is little risk of damage occurring to the components from such events.
