Other Installation Considerations
Pipe Hanger
When using a pipe hanger, ensure that the heating cable is
not pinched between the pipe and the hanger. Damage to
the cable can result in electrical arcing, arc faults, and arc
flashes.
Slab Penetrations
Before installing heating cables on a pipe that penetrates a
concrete floor or wall, be sure that the hole comfortably fits
both the pipe, cable, and insulation. Do not damage or cut
the heating cable during installation. Make sure that the cable
is not pinched between the pipe and the concrete floor and
wall when the hole is sealed. When fire stopping around floor
and wall penetrations, aviod damaging or cutting the heating
cable. The heating cable should be protected by a tube or
conduit and should not be installed directly into the sealing
material.
Bending the Heating Cable
Do not attempt to bend the heating cable in the flat plane,
as it may be damaged. The minimum bending radius for all
Chromalox heating cables is six times the minor diameter.
Heat Sinks
Refer to the design specs or Table 3 to determine the amount
of heater cable you need to install on each heat sink. Install
the heater cable on the heat sinks as explained in installation
details AD5-AD12. However, remember that the detail is just
a guide. It is important to get the proper amount of heater ca-
ble on the heat sink, rather than exactly as the detail shows.
