Description

technical field

[0001] The invention relates to the field of optical cables, in particular to a cable testing device. Background technique

[0002] Compared with conventional cables, superconducting cables need to meet the three basic critical parameters of critical temperature Tc, critical magnetic field strength Hc and critical current density J in order to maintain their superconductivity and ensure reliable, safe and effective operation of superconducting cables. The temperature conditions for the operation and testing of high-temperature superconducting cables are generally met by liquid nitrogen cooling, and liquid nitrogen impregnation is usually used to meet the critical temperature of high-temperature superconducting cables. Therefore, as liquid nitrogen storage containers for short samples of high-temperature superconducting cables Pressurized test equipment is essential for intercept tests.

[0003] At present, the common AC superconducting cables mainly include ...
