Features
PLS is an SF6-insulated pole mounted switch disconnector designed for overhead line installations up to 40.5kV 630A/1250A.
This outdoor switch disconnector is suitable for both remote control and manual operation with excellent load breaking and fault making capacity.
The tank fulfills the requirement of “sealed pressure system” meaning that there is no need to add gas during its expected lifetime.
The moving contact rotation with double swiching guarantee high dielectric strength during normal operation.
Construction Characteristics
The stainless steel tank is particularly suitable for providing protection against the extremes of heat, snow, corrosion, moisture and salt in the most demanding climatic conditions.
PLS is easy to install due to its reduced dimensions and weight and it is almost maintenance free.
