RSN-10 AND RSN-35 SERIES SWITCHGEARS |
 |
|
Metal-clad switchgears of RSN-10 and RSN-35 series are intended for reception and distribution of three-phase 50Hz electrical power in networks with isolated and grounded via an arcing ground suppressor neutral.
RSN-10 and RSN-35 metal-clad switchgears are used for electric power supply of industrial companies, oil and gas industries and electric power plants.
Metal-clad switchgears RSN-10M of marine design are used in power supply systems for marine vessels, floating structures and gas and oil platforms. Metal-clad switchgears RSN-10M have a corresponding certificate of type approval from the Russian Maritime register of shipping.
Main features:
-
panels of metal-clad switchgears are manufactured of galvanized steel thickness 2mm and have rigid steel design due to double bend technology;
-
panel’s enclosure consists of breaker, bus bars, cable and relay compartment. All 3 main compartments are independent and separate; this provides localization of emergence of short circuit through an arc within any panel’s compartments.
-
inside the compartment of busbars fully isolated silver-plated D-type copper buses are installed; due to this they have increased mechanical resistance.
-
metal-clad switchgears have all necessary mechanical and electrical interlocks to ensure safety of staff.
