UNKA ENGINEERINGEPC CONTRACTORPlant electrical architecture developed from load list, reliability target and utility interface.
Incoming supply, transformation, MV/LV distribution, protection and emergency power. The operating sequence, recycle paths, start-up/shutdown cases and normal/turndown behavior are defined before equipment finalization.
Transformers, switchgear, bus ducts, generators/UPS and distribution boards. Materials, design margins, maintainability, isolation, access, lifting and spare philosophy are coordinated with the approved operating cases.
Plant load/I/O lists, voltage and network philosophy, hazardous-area classification, availability targets, control narratives, package interfaces and cybersecurity requirements.
Load list, SLD, short-circuit/coordination, cable schedule, layouts and protection settings. The package also includes line/equipment lists, relief and utility summaries, layouts or 3D interfaces, vendor-document requirements, inspection plans and commissioning inputs as applicable.
Protection/selectivity, redundancy, fail-safe states, alarm management, segregation, earthing, functional-safety validation, FAT/SAT and controlled software backups.
Process plants, utilities, terminals and industrial facilities. Capacity, product quality, consumption and emissions commitments are confirmed only after the representative feed and project Design Basis are approved.
IEC 60076/60947/62271, IEEE where specified and local grid codes. The contractual code basis is selected by destination and client specification. ASME/API/TEMA, EN/DIN and GOST/EAC requirements are not mixed without an approved code-equivalency and authority review.
