Tx8 & Tx9 Transformer and Switchgear New Building - Retender
The building of a new enclosure over existing housings which contain the High Voltage (HV) Transformers, known as Tx8 and Tx9, together with the Low Voltage (LV) Switchgear which converts the HV supply into LV power which can be fed into the distribution boards in the buildings they serve.
