Miniature Substations: Compact, Integrated Power Excellence
Miniature Substations are the ultimate space-saving energy hubs, engineered to deliver robust power distribution in both urban and remote environments. Manufactured in strict accordance with Eskom and SANS 1029 specifications, our mini-subs integrate the transformer, high-voltage switchgear, and low-voltage protection into a single, secure, and weatherproof enclosure.
- Power Rating & Capacity Standard units are rated from 100 kVA up to 2000 kVA, catering to a wide range of residential and heavy industrial load requirements.
- Voltage Capability Engineered to handle voltages up to and including 22 kV, providing the necessary stepping for localized distribution networks.
- Manufacturing Integrity Produced 100% locally at our Proton Industrial Park facility, ensuring high-quality benchmarks and superior lead times compared to imported units.
- B-BBEE Empowerment Recognition As a Level 1 B-BBEE contributor, iPower offers 135% procurement recognition, enabling our partners to meet their local content and transformation goals seamlessly.
Your Main Heading
- Eskom & SANS 1029 Strict Compliance Every iPOWER mini-sub is manufactured in strict accordance with the latest SANS 1029 and Eskom technical specifications. This eliminates all regulatory risks for contractors and developers, ensuring your equipment passes municipal grid inspections seamlessly on the first attempt.
- Self-Contained & Weatherproof Engineering Designed for South Africau2019s harshest outdoor conditions, our enclosures feature high-durability anti-corrosive coatings and specialized ventilation. These units are engineered to protect critical switchgear and transformers against extreme UV exposure, high dust, and moisture for decades of reliable service.
- Versatile Switchgear & Custom Integration We offer the flexibility to choose the best protection for your project. Our mini-subs can be configured with SF6, Vacuum, or Oil-insulated switchgear, allowing for bespoke engineering that matches your specific operational safety requirements and existing infrastructure constraints.
