Appendix C low and medium voltage switchgear and associated equipment Updated.xlsx

This file is a pricing and service specification appendix for a maintenance contract covering low-voltage and medium-voltage electrical switchgear and associated equipment at a U.S. diplomatic facility in Frankfurt, Germany. The appendix details quarterly facility management meetings, 365-day on-call service availability (including weekends and holidays), project management, certified staff requirements, and estimated incidental expenses of €5,000. The maintenance scope encompasses annual visual inspections and cleaning of low-voltage switches (77 3WE circuit breakers, 30 3WL circuit breakers, 15 3VL circuit breakers, and 5 inspection stations), medium-voltage field inspections at four stations (25 total fields), and verification that short-circuiting and grounding devices comply with rated values.

Additional maintenance requirements include periodic protection testing every four years for 18 pieces of medium-voltage equipment, comprehensive battery system checks (charging, density, connections, cell state, charger functionality, and voltage detector adjustments), transformer maintenance comprising cleaning of insulating parts and rooms, Buchholz protection functional inspections, oil measurements, and insulating agent inspection per VDE 0370 Part 2 standards. The contract also requires visual inspection and documented assessment of 16 KV boxes, with findings recorded via structured checklists and photographic evidence to identify condensation, moisture, corrosion, foreign matter, and loose connections. All personnel must hold valid manufacturer-specific certifications for Siemens systems (8DJH/8DH10 MV, SIVACON/SENTRON LV, GEAFOL/Tumetic transformers) and industrial battery systems, with core maintenance tasks and functional testing restricted to after 18:00, weekends, or public holidays to avoid disrupting diplomatic operations.
