Frequently Asked Questions

Turn-key electrical contracting means that a single EPC contractor assumes total responsibility for design, procurement, installation, testing, and commissioning. The client receives a fully operational facility without managing multiple vendors. At AYÇE Endüstriyel, we manage the entire project lifecycle end-to-end under single-point accountability.

ATEX compliance is mandatory for any environment where flammable gases, vapors, or combustible dusts are present in explosive atmospheres. Key examples include petrochemical refineries, paint and solvent manufacturing plants, LPG bottling facilities, pharmaceutical plants, and flour/sugar storage facilities. ATEX zone classifications are determined through comprehensive site assessments conducted by certified engineers.

The execution process follows key sequential stages: needs assessment & load calculation → preliminary utility grid approval (e.g., TEDAŞ/DSO) → engineering design → equipment procurement → civil works & electromechanical installation → testing & commissioning → final grid connection approval. Depending on scope and scale, execution typically takes between 4 and 16 weeks.

Low Voltage (LV) systems operate below 1,000 V and cover intra-plant power distribution, lighting networks, and general power outlets. Medium Voltage (MV) systems cover installations operating between 1 kV and 36 kV, encompassing transformer substations, switchyards, and main bulk power distribution networks.

Yes. Under local high-voltage regulation standards (such as EKAT), facilities operating MV/HV equipment must formally designate a certified electrical engineer as their High Voltage Operation Responsible Person. This engineer must be registered with the Chamber of Electrical Engineers (EMO) and formally accept duty notification with the regional grid operator. AYÇE Endüstriyel provides outsourced HV Operational Responsibility services.

Harmonic analysis is required when adding variable frequency drives (VFDs), UPS units, or high-power motors; experiencing unexplained energy billing surges; encountering abnormal equipment overheating or failures; or when mandated by grid operators. Additionally, harmonic measurements are mandatory prior to installing power factor correction (PFC) systems.

Timeline depends on facility size and system complexity: small-scale SCADA deployments typically take 4 to 8 weeks; medium-scale projects take 8 to 16 weeks; and large, complex industrial projects range from 3 to 6 months. This timeline includes architecture design, control panel manufacturing, PLC/SCADA programming, installation, and commissioning.

For MV/HV installations: visual inspections should be performed monthly, functional testing quarterly, comprehensive preventative maintenance annually, and official statutory inspections every 3 years. For LV installations, annual comprehensive maintenance is generally sufficient. Under Occupational Health & Safety regulations (e.g., Law No. 6331), facility owners are legally obligated to maintain these records.
