摘要

The ESA consists of an outer layer (1),insulation layer (2),metal layer (3) in the form of an armour, middle part with filling (5),metal screens (4, 6),single metal core (7),fibre optic (8). At least one tube (9) with at least one single mode filament lamp (10) shall be fitted to the filling (5),and a tube (11) with at least one filament (8) is placed in the metal core for temperature measurements.
