Voltage indicator UNN-1E SZ VLE ELEKTRO TREID ET-UNN117

UNN-1E SZ VLV voltage indicator is designed to check the presence or absence of voltage on AC overhead lines with a frequency of 50Hz and DC voltage of 25-600 V. When supplied with two SHO-10E-4-7,0 poles, 7,0 m in length, the indicator allows determining the presence of voltage on overhead lines from the ground surface without climbing the VLV support.
