PSE-PSL

Product catalog summary
Features
The document describes a cast resin bushing designed for both indoor and outdoor applications. It is constructed from cycloaliphatic resin with OT58 brass fittings and includes brass nuts, washers, an NBR O-ring sealing gasket, and screws for securing the bushing to a tank. The bushing is used to connect two Medium Voltage air-insulated ends in a system, with an operating temperature range from -25°C to +100°C.
Standards
The bushing complies with IEC 60137 and Enel 3053C standards (the latter applicable only to PSL models).
Routine Tests
Routine tests include visual and dimensional checks, glass transition temperature, dry power frequency withstand, and partial discharges.
Tests on Demand
Additional tests available on demand include dry lightning impulse voltage, bending stress, and high-temperature tests.
Specifications
The document provides detailed specifications for various models of PSE and PSL bushings, including maximum operating voltage, lightning impulse voltage withstand, power frequency voltage withstand, and rated current. For example, the PSE 12/250 model has a maximum operating voltage of 12 kV, a lightning impulse voltage withstand of 75 kV, a power frequency voltage withstand of 30 kV, and a rated current of 250 A. The specifications vary across different models, with the highest rated current being 1000 A for the PSE 36/1000 model.
