PRECISION COMPRESSION MOUNTING CLAMP SYSTEMS
Wakefield Engineering compression pack heat sinks and clamp systems provide electrical and
industrial equipment manufacturers with complete system solutions for proper installation and
heat dissipation for high-power compression pack semiconductor. All components for device
mounting and cooling are available separately for all standard compression requirements from
800 lbs (362.9 kg) to 16,000 lbs (7,257.5 kg) force in both natural and forced convection ap-
plications.

These high-quality mounting clamp assemblies are the worldwide standard for mounting,
compression, and clamping press-pack SCR, thyristor, rectifier, and other high power disc
packaged devices utilized in power distribution equipment, industrial controls, transportation
systems, and power supply and conversion systems.
Clamp assemblies will accommodate devices with overall case diameters to 5.25 in. (133.4
mm) maximum. Vertical device mounting space available for assemblies is determined by se-
lecting an appropriate series crossbar by length which, when a series spring assembly is se-
lected (based on maximum clamping force required), will provide the necessary vertical clear-
ance space. For the 130 and 139 Series, this determination is made by subtracting the chosen
spring assembly “Z” dimension (refer to dimensional tables) from the crossbar assembly “X”
dimension minimum and maximum values, to calculate the available device mounting space
clearance for the particular assembly combination. Spring assembly “Z” dimension is the di-
mension measured from the spring assembly device mounting surface to the spring assembly
top surface. Some series have fixed dimensions for alpha characters. All spring assemblies are
designed with a force indicator gauge.
