Voltage detector with combined signalling VHV 123 kV

Type: 840.123

for outdoor use

Voltage detectors are designed for detecting the presence of very high voltage (frequency of 50 Hz). Presence of voltage is indicated by light and acoustic signal during direct contact with hot part. Insulating pole is made of glass – fibre laminate which is suitable for its high electrical and mechanical resistance and stability. It fulfills the requirements on the protective equipment for outdoor use. The detector is determined for outdoor use under normal climatic condition. The indication head is resist of water. The handle is equipped with a protective rubber ring (hand guard) and insulating part with rubber rings to stop water (rain shed). Voltage detectors comply with standards ČSN EN 61243-1, IEC 61243-1.
