Workers install the undersea power cable to Vinpearl Land off the coast of Nha Trang’s Khanh Hoa Province.

Electricity has been delivered from the mainland to a famous five-star tourism island off the central coast of Khanh Hoa Province by underwater cable that cost more than VND25 billion (US$1.4 million).

The 3,400 meters of cable with 12 megavolt amperes capacity, from Phu Quy Port to Vinpearl Land, is replacing the island’s power generators.

It is the first underwater cable in the national power grid.

The 22 KV, three-phase XLPE cable is installed 1-2 meters deep in the mud and fixed with concrete anchors 10-20 meters apart.

Nguyen Trong Hien, general director of Vinpearl Land Company, said the cable is “a big success” in improving infrastructure at Vinpearl Land to make it more attractive to tourists.

The power will also facilitate security and marine activities on Tre Island, Hien said.

Vinpearl Land is expected to recoup the money invested in the cable project in one year, he said.
