In order to provide personnel protection from high voltages, the substations have three separate compartments:
- HV Compartment
- LV Compartment
- Transformer compartment
Our Substations are factory assembled compact units and are designed to provide a completely self contained load centre.
Each unit is comprised of three individual main assemblies and a typical substation would include:
- One metal clad 11kV, gas insulated, circuit breaker ring main unit available from our range;
- One 11/0.4kV 500kVA , 1000kVA or 1500kVA dry or sealed transformer.
- One low voltage distribution board with ratings of 800A, 1600A & 2500A according to transformer size.
The Enclosure is of galvanised sheet steel, free standing, outdoor type on steel base. Steel plate and channels are used for the fabricated base structure and finished with polyester electrostatic powder paint. Lockable doors are provided for access to the transformer, HV and LV compartments. Ventilation louvers are provided to supply adequate ventilation for the transformer compartment.
The compact substations are designed to be lifted either from the underbase or from the top.
