Linear rod composite support insulator OLSK 16-20-A-4

They are intended for fixing and isolation of uninsulated and insulated wires of CIP-3, PZV and PZVG type on overhead power lines and switchgears of power stations and substations of alternating current voltage of 20 kV with frequency up to 100 Hz at ambient air temperature from minus 60 º? to plus 50 º?.
Climatic design and placement category UHL 1 according to GOST 15150.
The wire can be fixed in the trough or on the neck of the insulator. Fastening to metal structures of supports (traverses) is carried out by means of bolt connection. The design of insulators of modification "A" allows to roll CIP-3, PZV and PZVG wires directly on the insulators without the use of rollers. This shortens the installation time and reduces its cost. After rolling the wires on insulators modification "A" they should be fixed in the trough or on the neck of the insulator on straight sections of the line and on the neck - when turning the line..
