Zusammenfassung: | The utility model relates to an oil leakage detection cable and an oil leakage detection device. The oil leakage detection cable comprises a cable core, an oil absorption expansion sleeve and a protection sleeve, the cable core comprises an isolation wire, two signal wires and two sensing wires, the isolation wire and the two signal wires are annularly arranged, the signal wires are provided with first insulation sleeves, the sensing wires are arranged between the signal wires and the isolation wire, the two sensing wires are spaced, and the protection sleeve is arranged between the two sensing wires. The oil absorption expansion sleeve sleeves the wire core, the sensing wires are separated from the oil absorption expansion sleeve, and the oil absorption expansion sleeve is in contact with the two sensing wires to form a conductive loop after being expanded; the protective sleeve is arranged on the oil absorption expansion sleeve in a sleeving mode, and holes are formed in the protective sleeve so that oil ca |
