Thermal Contraction and Expansion of Cable Tray
All materials expand and contract due to temperature changes. It is important that cable tray installations incorporate features which provide adequate compensation for their thermal contraction and expansion.
Thermal Expansion & Contraction of Steel Cable Trays
If not properly accommodated, the accumulated length change can: Buckle or deform the tray system in summer (expansion). Pull apart joints or shear bolts in winter (contraction). Crack
