Support insulators IOL-10 are designed for rigid fastening of live parts in electrical apparatuses, switchgears, which are under voltage, to the main part of the structure and isolation of live parts from earthed elements. Insulators are used in electrical installations for voltage class up to 10 kV inclusive.
Climatic version "UHL", placement category 2 according to GOST 15150. IOL-10 insulators with letter "D" are designed to work together with a voltage indication device.
Thanks to the capacitive divider built into the housing, the device allows to receive data on the presence of voltage on the connecting current-carrying element. The corresponding light signal is reflected on the voltage display unit.
The voltage sensor is connected to the voltage indication unit via a threaded contact at the base of the insulator.
