- Low Voltage Compartment : This compartment contains all secondary circuits for measurement, protection, control, monitoring, communication and other associated systems.
- Busbar Compartment : This compartment contains electrolytic copper busbars and disconnector switches according to rated current. Access to busbar compartment is possible with special safety procedures and tools.
- Switching Compartment : This section contains the following personels in accordance with the project requirments.
– SF6 gas or vacuum circuit breaker with front mechanism,
– Withdrawer ers (excluded SNC-0.DB),
– Automatic shutters for busbar and cable connections,
– Mechanical interlocks between circuit breaker, withdrawer ers, shutter and door. - Cable Compartment : This compartment contains of instrument current, voltage transformers, surge arrestor, AktifSES series earthing switch, capacitive voltage divider, cable gland and fittings.
- Withdrawable VT Compartment : In this section, which is in the SNC-2.Dbseries Metal clad switchgear, there are voltage transformer, voltage transformer withdrawer ers and fuses.
SNC series Double Busbar Medium Voltage Metal Clad Switchgears are used in ersonel facilities needs high level safety and energy continuity. Cassette type withdrawable circuit breaker and withdrawable voltage transformer provides easy and fast operation and minimizes the installation and maintenance time of your facility. Actif SNC series Double Busbar Metal Clad Switchgears provide a high level of security against fault maneuvers with mechanical and electrical interlocks.
Aktif SNC series Double Busbar Metal Metal Clad Switchgears save area with their minimized dimensions and compact designs and suitable switchgears to be used in indoor applications.
With the arc pressure relief channel option, the arc, pressure and harmful gases that occur at the time of failure are discharged to the outside without damaging the ersonel and other devices in the room.
Aktif SNC Series Double Busbar Medium Voltage Metal Clad Switchgears can be produced for tropical ambient conditions.
Aktif Elektroteknik has TSE, ISO 9001, ISO 14001 and ISO 45001 quality certificates. Aktif SNC double busbar metal clad switchgears offer economic and long-lasting solutions for your facility and reliability is supported by a 5-year warranty option.

What are the working principles of SNC-DB series Metal Clad Double Busbar switchgears?
In double busbar systems, there are 2 busbars and main supply independent of each other. With SNC-DB series Metal Clad Double Busbar LSC-2B type switchgears, loads can be supply in such a way that energy can be taken from both busbars. In this way, in case of malfunction or maintenance in any busbar, transformer or breaker feeding the busbar, the energy transfer can be transferred to the other busbar without interruption. In addition, load sharing between the busbars, load transfers, system expansions can be done as desired without power interruption. With the double busbar system, isolation of special output loads from the network can also be provided.
