Metal-clad switchgears RSN-10 and RSN-35 |
 |
|
Metal-clad switchgears RSN-10 and RSN-35 are intended for reception and distribution of electricity of three-phase AC frequency 50Hz with isolated and grounded via an arcing ground suppressor by a neutral.
Metal-clad switchgears RSN-10 and RSN-35 are used for electric power supply of industrial companies, oil and gas industries and substation of electric networks.
Basic differences:
-
Panels of metal-clad switchgears are manufactured of galvanized steel thickness 2mm and have rigid steel design thanks to double bend technology;
-
Panel’s enclosure consists of breaker, bus bars, cable and relay protection and automation compartment. All 3 main compartments are independent and separate; these limit their interplay and provide localization of emergence of short circuit through an arc within any panel’s compartments.
-
Full isolated silver plated D-type copper buses are installed into the compartment of bus bars, at the expense of it they have increased mechanical resistance.
-
Metal-clad switchgears have all necessary mechanical and electrical interlocks for safety precautions of staff.
