Seondo Electric
Description
Apply Pole Mounted SF6 Load Switch is installed on the concrete electric poles in order to the load in the distribution sector on the 25.8kV 400A processing line.
Insulation and breakage by SF6 Gas
As an insulation medium, by using SF6 Gas, this switch has excellent capacity for insulation, compared with air or oil. Since the outer surface and other parts are made of stainless steel, it is a witch not requiring any repair and usable almost permanently.
High Reliabilty
Since the electric conduction part in it is completely sealed, and it has excellent insulated electric lines, the switch is easy to function as well as is free from accidents resulting from the contact with salt, air pollution, and strange materials.
Safety
In case of abnormal rise of interior pressure of the switch, it is equipped with pressure-proof equipments which can prevent the vessel from being destroyed or being hattered.
Easy Installation
By using hanger type, Light-weight design for easy pole mounting
