China Shenhua Energy Co, the nation's largest coal producer, attracted at least 2.6 trillion yuan of orders for its Shanghai share sale, a record, said sources.

The offer drew over 1.9 trillion yuan from retail investors and more than 700 billion yuan from institutions, they said, citing preliminary tallies and asking not to be identified before an official announcement.

Beijing-based Shenhua will sell as many as 1.8 billion shares at between 34.99 yuan and 36.99 yuan each, it had said.
