Heating pipe and electrical cable conduit - has respective conduit regions for heating pipes and electrical cables separated from one another via hollow space for thermal insulation

摘要

The conduit allows reception of heating pipes (41,42), carrying a heat transfer medium and electrical cables (51,52,53), for supplying electrical loads. The heating pipes and the electrical cables are received in respective regions (4,5) of the conduit, separated from one another by a hollow space (2). Pref. the hollow space is filled with a thermal insulation material, e.g. an insulation foam, with a thermal conductivity ensuring that the temp. within the conduit region (5) receiving the electrical cables does not exceed 25 degrees C.
