An
advanced approach to busbar insulation.
New designs of switchgear for voltages upto 36kV follow the
principle for reducing size as much as possible. Insulated
busbars are necessary to provide maximum protection,
particularly in confined spaces, against flashover &
accidentally induced discharge. Choosing the right busbar
insulation can be difficult.
To solve this problem, Raychem has developed a series of
heat-shrinkable tubing in the Raysulate product line, for use on
both aluminum & copper busbars of circular & rectangular
cross section. BBIT/BPTM tubing is highly flexible and has
been installed on a wide range of curved & bent busbars
without cracking or creasing.
BBIT/BPTM tubing can easily be installed in factories in large
scale production using a hot air oven or on site using a simple
electrician's torch or hot air device. On application of
heat in excess of 1250C the tubing shrinks onto the busbar,
closely confirming to the busbar profile & ensuring that the
required minimum wall thickness is always obtained. |
