| 释义 | > as lemmaspressure cable pressure cable n. Electrical Engineering a paper-insulated cable containing gas or oil under pressure within the outer sheath or pipe, the pressure counteracting the tendency of the insulation to separate from the conductors in operating conditions and enabling higher voltages to be used.

Hochstadter et al. in Jrnl. Royal Soc. Arts 80 95 The utilisation of an impregnated paper cable..could be greatly increased if it were possible to get rid of the heterogeneity in the dielectric, or to render it harmless... It is possible to do this... (b) By radial compression of the cable in such a way that the radial ‘breathing’ is reversible at all temperatures, such vacuous spaces as tend to form being closed by the compression or the pressure in them raised to such an extent that no ionisation takes place. The latter alternative leads to the ‘Pressure Cable’. 1966 IEEE Trans.
