Substations & Transformers
DESIGNED PRIMARILY WITH THE SAFETY OF PEOPLE AND RELIABILITY OF SERVICE IN MIND.
DESCRIPTION
IGP internal arc-protected miniature substations are manufactured in-house and are available in a range of configurations to suit almost any client requirement. Designed primarily with the safety of people and reliability of service in mind, IGP miniature substations contribute to improving electrical distribution in medium voltage networks. Stringent quality control and test procedures in our manufacturing facilities assure the highest levels of quality in IGP miniature substations
PRODUCT INFORMATION
May be ordered with any oil, air, vacuum or SF6 Ring Main Unit. Our units are designed to accommodate any Ring Main Unit. A wide variety of transformers from 315kVA to 1250KVA. Transformers may be specified as oil-fitted or dry-type for mining applications. Off-load tap switches may be specified to SANS, IEC or NRS specifications. Voltages range from 6.6kV to 33kV. Custom-built miniature substations available up to 2MVA. All components can be installed to specifications.
CONSTRUCTION CHARACTERISTICS
High-quality, folded sheet metal customizable housings manufactured at our in-house sheet metal factory (mild steel or 3CR12 – coastal). Re-enforced hot dipped galvanised steel channel bases. Fully automated power-coating plant allows for the provision of any colour or texture. Fully segregated compartments for the Medium Voltage Ring Main Unit, transformer and Low Voltage compartments. Robust, removable roofs ensure easy access by authorized personnel.
COMPLIANCE WITH TECHNICAL REGULATIONS AND STANDARDS
All transformer substations are manufactured in accordance with client requirements and installation area, therefore all miniature substations will comply to regulation legislation required (SANS, IEC, BS, NRS). Applications: Utilities, Housing & Commercial developments, Mining, Industrial facilities .etc

Cast Resin Transformers
Ruhstrat offers cast-resin transformers with power outputs up to 20 MVA and series voltages up to 36 kV, as power converter, distribution or special transformers. Ruhstrat cast-resin transformers feature numerous functions which make them a very reliable and safe solution. To ensure optimal products, materials from first-class suppliers are used, such as grain-oriented electric sheets, aluminium and copper coil material using band and foil technology, as well as high-quality insulating materials (cast resin, Mylar, Nomex).
CAST-RESIN TRANSFORMER TYPES
DistributionTransformer for 6, 12, 18 or 24 pulse rectifier operation Double-stack transformer and multi-winding transformer Step-up transformer Transformer for wind power Starting transformer Test transformer, e.g. in combination with a variable transformer
RUHSTRAT CAST-RESIN TRANSFORMERS
Ruhstrat cast-resin transformers are manufactured in accordance with IEC 60076-11:2004, VDE 0532-76-11:2005-04, DIN EN 50588-1:2016-03, Regulation (EU) Nr. 548/2014 as well as special country-specific regulations and customer requirements. Due to compliance with climate class C2, environmental class E2 and fire class F1, they fulfil the most stringent requirements for safe installation in residential and work environments.
ADVANTAGES
Individual solutions, which fulfil special requirements with respect to the operating mode, low-noise and low-loss design, connection technology, cooling, transport and setup are possible at any time.
