1322883 Heat generating pipes CHISSO CORP 18 Jan 1972 [18 Jan 1971] 2338/72 Heading H5H A heat-generating pipe arrangement, similar to that of Specification 1,179,031, is distinguished by having in the ferromagnetic pipe 1 a gas under superatmospheric pressure, the pressure being such that the corona initiation voltage of the insulated conductor 3 is greater than the maximum service voltage of the conductor. A gas pressure of 3 to 7 kg/cm.<SP>2</SP> is appropriate for a source voltage of 1000 V. The gas is air supplied via an inlet near the source 8, Fig. 3 (not shown). |
