Green Transformer Program- BIOTEMP

• ABB Transformers Egypt participated in Cairo exhibition “ Electricx 2011 “ with its

produced BIOTEMP 500 kVA 22/0.4 KV. Indicating the following advantages :

1- BIOTEMP is human and nature friendly

2- BIOTEMP can withstand cont. over load 10 % starting from full load without more

cooling.

3- BIOTEMP fire point temperature is more than 300C.
