PURPOSE:To stably hold a current detector in a fixed position by providing a tension member anchor or the like on the outside of the case of the current detector. CONSTITUTION:A tension member anchor 4 is attached to the outside of a case 1a of a current detector 1, and the terminal of a tension member 5a of an optical fiber cable 5 for signal transmission fixed to an iron tower is detained by this anchor 4. Clamping metal fittings are used to fix the cable to an optical fiber composite overhead earth wire 3 also for the purpose of increasing the fixing capability of the detector 1. The cable 5 extended from the detector 1 is connected to an optical cable led out from the overhead earth wire 3 in a connection box. By this device, the cable 5 tenses to detain the detector 1 and the detector 1 is prevented from slipping down even if the clamping part of the detector to the earth wire 3 is loosened. Since the anchor 4 is provided on the outside of the case 1a of the detector 1, enlargement of the detector 1 is avoided.
