Compact substations are self-contained units available in different designs and dimensions and cater for power supply requirements for residential and industrial consumers.
Each unit comprises of three individual main assemblies, and a typical substation would include:
- One hermetically sealed transformer.
- One metal clad high voltage Ring Main Unit.
- One metal clad low voltage distribution panel.
Construction
Metal clad with polyethylene housing or with glass reinforced plastic housing.
Powder coating with excellent finish.
Lifting lugs for mounting the substations from the base. Easy assembly.
Maximum degree of protection-IP43.
High Voltage Switchgear
SF6 insulated ring main unit circuit breaker/Fused switch.
Oil insulated ring main unit with fused switch.
Oil/SF6 insulated isolator.
Air or vacuum insulated fused load break switches
Low Voltage Switchgear
Incoming breaker or isolator up to 3200A (Motorized or manual draw out).
Outgoing breakers/Fused switches.
Computerized load monitoring relays (Available on request).
Instrument transformers/meters from reputable manufacturers.
Transformer
Hermetically sealed oil immersed transformer with corrugated fins or with radiators, or vacuum cast resin transformer.
Note: For compact substations projects, it is absolutely necessary to provide detail drawings for quotation.
Other compact substations.
Underground prefabricated substations
Combined transformers and prefabricated substations used for wind power generation.
