EXPANSION JOINTS


Depending on load condition and the external environment, the conductors may have a tendency to contract/expand (Thermal expansion). Specially designed expansion joints are provided to suppress those effects.

Expansion joints are recommended on every 40  m runs of straight conductor and also when the busway crosses the building expansion joints. These joints are normally   designed   for +/-30mm   length.   Special designs are also available for up to +/-90mm.
