The project is constructed to replace the
existing 220kV transmission line which has operated over 20 years and become
degraded. It aims at increasing transmission and connection capacity of
regional power system, strengthening reliability, providing a stable and
uninterrupted power supply for the Southern West areas.
The project has total cost of over VND 911
billion, invested by National Power Transmission Corporation (EVNNPT), SPMB is on behalf of EVNNPT to manage the project, Power
Engineering Consultation Company No. 2 (PECC2) is responsible for project
design; Power Construction Company No. 1 (PCC1) is responsible for
implementation; the project will be assigned to PTC4 for management and
operation after its completion.
The scope of project “Improving and Upgrading
the 220kV Phu Lam – Cai Lay 2 transmission line” is as follows:
- Project 1 – Improving, upgrading
the 220kV Phu Lam – Long An transmission line: From 500kV Phu Lam
substation, tensioning 220kV double circuits in 3 circuit tower of 500kV Phu
Lam – O Mon transmission line (1 circuit at 500kV and 2 circuits at 220kV); the
remaining section will be in right of way of the 220kV Phu Lam – Cai Lay 1
transmission line in order to improve to 2 circuits at 220kV running to the
220kV Long An substation.
- Project 2 – Improving, upgrading the
220kV Long An – Cai Lay 2 transmission line: Improving the 220kV Long An –
Cai Lay 2 transmission line from 1 circuit to 2 circuit in the existing
transmission line right of way (RoW), replacing some equipment of 2 220kV feeders
connecting to 220kV Cai Lay substation at existing 220kV Long An substation.
The transmission line has a length of 30 Km, running
through Binh Tan precinct, Binh Chanh district, Ho Chi Minh city; Ben Luc, Thu
Thua districts and Tan An city of Long An province; Chau Thanh, Cai Lay
districts of Tien Giang province.
This is one of urgent projects aiming at
reducing power loss and overload for the existing transmission line. The
project requires high efforts and determination by SPMB, with frequent presence
by leaders and staff, even in weekends and holidays, to settle occurred
problems, because this is an improved project, implemented in existing old and
in-operation transmission line, with many difficulties faced in power cut-off
for foundation digging, tower erection and conduction tension.
The energized project 1 will contribute to
ensuring a stable, secure, un-interrupt power supply for serving socio-economic development,
especially ensuring power supply to Ho Chi Minh city, Long An province and
surrounding areas./.
