SNC-DB series Metal Clad switchgears are manufactured in three types;

SNC – 0.DB: with fixed SF6 gas-insulated or vacuum circuit Circuit Breaker

SNC – 1 .DB: with withdrawable SF6 gas-insulated or vacuum circuit Circuit Breaker

SNC – 2.DB: with withdrawable SF6 gas-insulated or vacuum circuit Circuit Breaker and Voltage Transformer

Metal Clad Switchgears consist of 4 independent compartments for SNC – 0.DB and SNC – 1. DB types, 5 independent compartments for SNC-2.DB type;

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 the busbar compartment is possible with special safety procedures and tools.

Switching Compartment: This section contains the following equipment in accordance with the project requirements.
– SF6 gas or vacuum circuit breaker with front mechanism
– Withdrawer unit (excluded SNC-0.DB)
– Automatic shutters for busbar and cable connections
– Mechanical interlocks between the circuit breaker, withdrawer unit, shutter and door.

Cable Compartment: This compartment contains 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 a voltage transformer, a voltage transformer withdrawer unit and fuses.

SNC series Double Busbar Medium Voltage Metal Clad Switchgears are used in safe facilities for needs with high-level safety and energy continuity. Cassette-type withdrawable circuit breaker and withdrawable voltage transformer provide easy and fast operation and minimise the installation and maintenance time of your facility. Actif SNC series Double Busbar Metal Clad Switchgears provide a high level of security against fault manoeuvres with mechanical and electrical interlocks.

Aktif SNC series Double Busbar Metal Metal Clad Switchgears save space with their minimised dimensions and compact designs, and are 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 personnel and other devices in the room.

Aktif SNC series Double Busbar Medium Voltage Metal Clad Switchgears can be produced for tropical ambient conditions.

Aktif SNC series Double Busbar Metal Clad Switchgears are manufactured in compliance with successfully passed type tests successfully in the accredited international laboratories in Europe according to IEC 62271-200 and TSE EN 61271-200 standards. SNC series Medium Voltage Double Busbar Metal Clad Switchgear have TSE, ISO 9001, ISO 14001 and ISO 45001 quality certificates and a domestic goods certificate.

With a 5-year guarantee option, SNC series Metal Clad switchgears provide a high level of reliability for facilities.
