Vietnam: NPT has started construction of five 220 kV transformer substations

On December 25, 2016, the Central Power Management Board (CPMB),
Contractors, Local Administrators and relevant agencies started construction
of five 220 kV transformer substations (TS) planed in 2016 as Luu Xa (Thai
Nguyen), Nong Cong (Thanh Hoa), Phong Dien (Thua Thien - Hue), Phu My (Binh
Dinh) and Dak Nong (Dak Nong province).

Luu Xa 220/110/22 kV TS includes a 250 MVA transformer, a 220 kV double
circuit line (conductor of 2xACSR/43) with a length of 0.94km from Luu Xa TS
to 220 kV Thai Nguyen - Phu Binh line, 727.8 m of 22kV line, supplying self-
use electricity for Luu Xa TS. The total investment level of the project is
VND 269.67 billion.

Nong Cong 220/110/22 kV TS includes a 250 MVA transformer in the first stage
(full scale of 2x250 MVA), two 220 kV double circuit lines from 220 kV line
Nghi Son - Thanh Hoa to Nong Cong TS of which a line of 1,353 m and another
one of 1,398 m. The total investment level of the project is VND 434. 694
billion.

Phong Dien 220/110/22kV TS includes a 125 MVA transformer (full scale of
2x125 MVA) appointed from other place, a 220 kV double circuit line from 220
kV Dong Ha - Hue to Phong Dien substation with a length of 1,346m and a 22kV
double circuit line for TS self-use with a length of 936m. The total
investment level of the project is VND 205. 140 billion.

Phu My 220/110/22kV TS includes a 125 MVA transformer (full scale of 2x125 +
250 MVA), 8 cupboards of 220 kV distribution system and 15 cupboards of
110kV distribution system, a 220 kV double circuit line with a length of
1.712km for connecting with 220 kV being constructed Quang Ngai - Quy Nhon
(Phuoc An) and a 22 kV line with a length of 668m for supplying TS self-use.
The total investment level of the project is VND 241. 311 billion.

Dak Nong 220/110/22kV TS includes 2x 125 MVA transformers, a 220 kV double
circuit line (conductor of 3xACSR330/43) with a length of 1.19km for
connection with 220 kV double circuit line from Dak Nong 500/220 kV TS to
220 kV TS of Aluminum Electrolysis plant, and a 22 kV line with a length of
0.45km for supplying TS self-use. The total investment level of the project
is VND 364.085 billion.

These projects invested by credit loans and own capital of the EVN National
Power Transmission (EVNNPT), and managed by CPMB on behalf of EVNNPT expect
to be completed from Quarter IV/2017 to Quarter II/2018.
