SINGAPORE, Sept 30 (Reuters) - Buyout firms and asset managers are moving in on billions of dollars of infrastructure assets across Southeast Asia, lured by the sector's growth prospects and stable, long-term returns, bankers and analysts say.

Merger and acquisition deal volume is up in the sector so far this year, data shows, and a healthy pipeline of deals could make Southeast Asia a rare bright spot for global funds as they grapple with rising finance costs and slumping markets.

The industry is also flush with potentially available assets, after a boom in infrastructure development fed by rapid economic growth.

Telecom operators including PLDT in the Philippines and Indonesian carriers, grappling with tight margins and burdensome debt, have done sale and lease back transactions for thousands of cell phone towers.

"Southeast Asia is a highly sought-after market given the compelling growth outlook for infrastructure assets," said Ee-Ching Tay, head of investment banking for Southeast Asia at Barclays.

About 210 deals targeting Southeast Asia's industrial and telecoms sector have been announced so far this year, exceeding the 184 from the same period a year earlier, Refinitiv data shows, in contrast with a 9% drop across all sectors in the region, although deal value in the sector has declined.

Last year was a record for the sector, with some blockbuster deals, and analysts say the near-term pipeline is strong.

Possibilities include the data centre business of Malaysia's Time Dotcom Bhd, which has attracted bids from DigitalBridge Group and U.S. data centre firm Equinix and could be valued at about $600 million, sources familiar with the matter said.

The sources declined to be named because the discussions were confidential.

DigitalBridge declined comment, while Equinix and Time Dotcom did not respond to requests for comment.

In another deal that could be worth up to $3 billion, sources familiar with the matter told Reuters last week that Canadian pension fund and buyout firms are among potential suitors for a toll road business put up for sale by CVC Capital Partners and its Hong Kong-listed partner with assets in Indonesia and China.

"Infrastructure assets are generally underpinned by long-term contracts, providing certainty of cashflows, which allows them to attract debt at high gearing to improve returns to investors," said Gilles Pascual, who leads EY's activities in Southeast Asian power & utilities sectors.
