Product Description

Application

Xucky’s high quality FLN36-12 Indoor High-voltage Sulfur Hexafluoride Ioad Switch is a medium-voltage switchgear developed by our company with reference to international new technology and according to the relevant standards of China's power system, and its performance indicators meet the national standard GB/T3804-2017 "3.6kV-40.5kV high-voltage AC load switch",which is the main switching element of the ring main unit.

The FLN36-12D/FL(R)N36-12D series indoor high-voltage sulfur hexafluoride load switch is a collection of brake, opening, grounding as one of the multi-functional medium voltage switchgear, in a fully sealed,with a reinforced structure of epoxy resin shell filled with O.O5MPa SF6 gas, with the least parts to achieve the above three functions,to ensure the quality of the product, improve the reliability.

It is maintenance-free and can operate safely for more than 20 years under normal conditions.
