Single core power cable laying system
专利汇可以提供Single core power cable laying system专利检索，专利查询，专利分析的服务。并且PURPOSE: To detect insulation fault points and facilitate repair by enabling a cable with cross-bonded sheaths to occupy the extended laying position which was occupied by that with pre-cross-bonded sheaths.
CONSTITUTION: The two insulating joint box IJs for each phase are set up and the sheaths RA1 to TB3 are cross-bonded between the termination box EB of a cable line consisting of three-metal-sheath-single-core power cables R, S, and T and the normal joint box NJ and between the adjacent normal joint boxes NJs. No DC ground is performed at the start and end of each cross-bonding section, but AC ground is done. A cable with cross-bonded sheaths occupies the extended laying position which was occupied by that with pre-cross-bonded sheaths. Measuring leads U, V, and W are individually lead to the anticorrossive layer insulation monitor K from a sheath series circuit.
