Prefab TNB Compact Substation

Prefabricated TNB Electric Transformer Substation for Electrical Grid Systems

 

 

Product Description

 

Voltage levels

 

• Typically used for medium voltage distribution up to around 12kV on the primary side.

• Step down voltage to 400V or 690V on the secondary side.

• Suitable for applications with transformer capacities up to around 1600kVA.

 

Design Specifications

 

• Enclosure protection rating of IP54 or higher to protect against dust and occasional splashing of water.

• Insulation class of at least E (140°C) for transformers and switchgear.

• Equipment and components meet IEC standards for electrical substations.

• Optional protective devices like surge arresters, instrument transformers, etc.

 

Temperature Control

• Natural or forced air cooling systems to dissipate heat from components.

• Temperature sensors to monitor ambient and internal temperatures.

• Temperature control units to regulate fan speeds, activate alarms, etc.

• Heat exchangers or liquid cooling for high ambient temperatures.

• Optional air conditioning for extreme conditions.

 

Operational Safety

• Integrated protection relays and circuit breakers for overcurrent, overload and short-circuit protection.

• Optional protective relaying for earth faults, over/under voltages, reverse power, etc.

• Islanding prevention to automatically disconnect from the grid during outages.

• Fire suppression systems and protective earthing.

• Alarms, indicators and control panels for monitoring and operation.

• Security measures like locking doors and intruder detection.
