Insulators OLK-4-20 UHL1

OLK series rod line insulators suitable for electrical insulation and installations of wires and anti-lightning rods for overhead lines and open high voltage power distributing units. OLK insulators have special construction intended for fastening 10kV wires on traverse or no traverse fastening to support. The distance between upper end with wire and lower probe is more than 100mm. Because of that insulator is brake resistant inside of glass-plastic composite which has electrical resistance more than 40kV to 1 cm. A possibility of installation in remote regions (swamps, mountains, forests…) makes them irreplaceable for using in oil and gas industry. In extreme situations OLK insulators can be dropped down from helicopters from height up to 15 meters right in factory packages. Breakage is not possible under conditions of normal transportation. Low weight and comfortable package allow to move decent quantities of insulators right in working places by hands, without using of machinery. The construction of insulators is patent protected.
 
Advantages of insulators OLK

Factory performed operation of joining insulation part to the probe of insulator excludes hard working in field environment. This eliminates a possibility of staff mistakes – “human factor”. The absence of polyethylene cap, that is losing mechanical properties under low temperatures, allows to operate OLK insulators down to – 60 C°.

Application and design recomendations

While designing electrical power supply lines it is necessary to apply typical solutions for insulating traverse on a basis of OLK insulator. The selection of typical solutions factory is able to send up on a written inquiry. Some important features and drawings are also placed in the ending part of this catalogue. The difference that traverse has is lack of installation probes, instead traverse has corresponding openings for fastening insulators of OLK type.
