If low-pressure air is not applied, it is important to seal the interface between the camera housing and the
outermost protective sleeve (e.g. with Kapton tape) in order to prevent hot ambient air from entering the
insulation. This is shown in Fig. 3.5.

In many cases also less efficient insulation arrangements may be sufficient. As an example, in moderate
ambient temperatures it may not be necessary to insulate the camera housing. Therefore, if needed,
space can be saved by protecting only the cables with protective sleeves. This is shown in Figs. 3.6-3.8
(please note that the steps shown in Figs 3.2 and 3.3 have been carried out beforehand). In this example
effectively three layers of Thermosleeve B have been applied, but the appropriate number of layers can
be smaller or larger, depending on the ambient temperature and application.
