Aktif SME-1 series Medium Voltage Metal Enclosed Switchgear is the switching and control cubicle which is manufactured between 1 kV and 40.5 kV voltage level. Metal Enclosed Modular switchgears are usually referred to as Metal Enclosed swicthgears. It is manufactured up to 40.5 kV voltage level at electrical values up to 1250 A, 25 kA / 1s. LSC-2A type Metal Enclosed Modular Switchgears consist of 3 independent compartments;

  1. Low Voltage Compartment : This compartment contains all secondary circuits for measurement, protection, control, monitoring, communication and other associated systems.
  2. Busbar Compartment :  This compartment contains electrolytic copper busbars according to rated current. Access to busbar compartment is possible with special safety procedures and tools.
  3. Switching Equipment Compartment
  • Switching equipment (withdrawable SF6 Gas insulated circuit breaker,  load break switch, SF6 gas insulated or SRS series air insulated rotary disconnector switch, vacuum contactor)
  • Current transformers
  • Voltage transformers
  • Surge arresters
  • Grounding
  • Capacitive voltage divider
  • Cable connection couplings

Withdrawable type SF6 gas insulated circuit breaker on the trolley in SME-0 series switchgears are removable before disconnecting their electrical connections. SMK series Monoblock concrete kiosks are SME series Modular Metal Enclosed Switchgears suitable for use in indoor applications such as SPK series prefabricated concrete kiosks, SCK series steel kiosks, industrial facilities and buildings. Medium Voltage Metal Enclosed Switchgear has a Modular compact design that allows any future extension. Aktif SME Metal Enclosed Switchgears can be produced in compliance with tropical ambient conditions.

Medium Voltage Metal Enclosed Switchgear is manufactured in compliance with passed type tests successfully in the accredited international laboratories according to IEC 62271-200 and TSE EN 61271-200 and TEDAŞ-MYD/95-007.E standards. They have successfully passed seismic type tests according to IEC62271-210, EN60068, IEEE693, GR-63-Core-Zone4 standards and are manufactured in accordance with type tests. SME series Medium Voltage Metal Enclosed Switchgear have TSE, ISO 9001, ISO 14001 and ISO 45001 quality certificates and domestic goods certificate.
