This switch is a switch for a 22.9kV overhead distribution line,and instead of the existing SF6 gas insulation method,it adopts an epoxy insulation method and a vacuum cutoff method,and it is a structure that does not require maintenance due to gas leakage or replenishment. Insulation leakage distance has been significantly increased by means of epoxy,and due to the excellent insulation performance of epoxy,it can be applied not only to general areas but also to areas that are salty and dirty,and the main body tank and control box are made of stainless steel,which is resistant to corrosion. The clamp type connection method is applied instead of the rescue line to increase the convenience during installation. The Spring Toggle method is adopted as an operation method,and it can be used as an automatic type by adopting a manual type or motor mounting and FRTU integrated digital control method. Performance verification has also been completed by an international testing and certification body.

responsibility

-Internal vacuum cut-off method adopted

-Improved switching performance and increased rated current 630A capacity

safety

-Prevents three-phase short circuit accidents with separate structure for each phase

-Resolve the risk of explosion of high pressure tank in SF6 gas insulation method

Environmentally friendly epoxy insulation

-Expanded leakage distance to 645mm with epoxy mold insulation structure

-Use of epoxy bushings that are resistant to contaminated environments can be applied to areas that are salted and contaminated.

-Maintenance-free structure that does not require gas and pressure release locking device [Maintenance Free]

Other technical notes

-The accuracy of voltage,current,and measurement has been improved to 1.0%,improving the reliability of line operation.

-Reduced installation load and improved ease of work by reducing the weight by more than 50% compared to the existing SF6 gas insulated load switch
