3.6‑36 kV indoor/outdoor special‑use RMU, optional IRTU‑integrated automation solution, self‑powered protection relay support, 50 Hz, inland/coastal anti‑corrosion design, for Eskom distribution‑automation & IPP projects.
This is Eskom’s utility‑grade procurement specification for factory‑assembled metal‑enclosed ring‑main‑units, targeting EPCs, tenderers and design institutes for tender response and pre‑award evaluation.
It references prevailing SANS and IEC standards, defines mechanical construction, protection‑relay functional matrix, remote‑control logic, anti‑corrosion grades, cabinet marking rules, type / routine / witness‑test requirements, tender deliverables and acceptance clauses.
It covers both inland and harsh coastal site conditions, supporting custom configuration and project‑specific FAT. Contact us for compliance‑check templates and complete qualification documents.
Maintenance-free 24kV to 33.5kV zero gas switchgear. Eco-friendly design for medium-voltage distribution systems ensuring safe and stable power.
Original manufacturer of 30-35kV solid insulated RMU. SF6-free, compact, low-maintenance, and high-safety design. Supports ring/dual/radial configurations for smart grids.
Two corrosion grades are defined: medium‑pollution inland condition and very‑heavy‑pollution coastal condition. Cabinet material, surface‑treatment and component selection must match site classification. Please contact us for environment‑adaptation advice.
Vendors may supply either self‑powered protection relay without external auxiliary supply, or advanced protection IED with rich setting characteristics; both shall satisfy defined protection logic and test requirements. Please contact us for protection‑scheme‑checklist.
Standard units adopt basic switching configuration. IRTU‑integrated version adds built‑in remote‑terminal‑unit, comprehensive protection logic, multi‑protocol SCADA interconnection and event recording for distribution‑automation and IPP scenarios. Please contact us for function‑selection guidance.
