EL KONTROL commissioned Substations Mayak 110 kV and Kavarna 110/20 kV, located in northwest Bulgaria. 

The two Substations are part of a common Project of NEK, concerning erection of a new junction 110 kV Substation Mayak, and also reconstruction and enlargement of 110/10 kV Substation Kanvarna.

110 kV Substation Mayak is a junction Substation destined to ensure a steady power supply able to sustain the increased loading of the northern Black-Sea area power distribution network during summer tourist season.
The Substation was erected from zero-level entirely by EL KONTROL.

In July 2013 we finished implementation of the Reconstruction and enlargement of 110kV Switchyard in 110/20kV Substation “Aytos”.

The site is located on the land of Aytos town, Bourgas Region. It has been assigned to EL KONTROL by the National Electric Company EAD.

On 23th April 2013 EL KONTROL took part in the "Apprentices" Еxhibition held by the Career Centre at the Technical University of Sofia.

The exhibition is traditionally popular with the students and gave us an opportunity to promote EL KONTROL amongst the young and ambitious engineers-to-be who seek good prospective for their realization.

The erected equipment successfully passed 72-hourly test-run and the construction site was taken-over by an Acceptance Committee with a Certificate Nr.15.

Under this project was implemented reconstruction of 110 kV Switchyard in the Substation by means of substitution of all 110 kV electrical equipment, and substitution of reinforced concrete constructions.

Works for modernization of 110/20/6 kV Substation Iztochna situated in Troyanovo-Sever Mine of Maritsa-East Mines were fulfilled.

In the Substation all the 6.3 kV Indoor Switchgears were substituted with new ones produced by ABB and equipped with SF6 circuit breakers.
