The Laos SAVAN1 Phase 1 Onshore Wind Project is a renewable energy project located near Phin District, Savannakhet Province, Laos. The project forms part of the country's growing wind power infrastructure and requires reliable medium-voltage electrical collection and distribution systems.
China Energy Engineering Group Guangdong Electric Power Design Institute Co., Ltd. (GEDI), an experienced Chinese engineering company serving power and renewable energy projects, is the EPC contractor for the project.
Anhui Tiankang Group was selected as the cable and cable accessories supplier for the project's electrical collection system, providing a comprehensive package of 35kV power cables, cable terminations, joints, low-voltage cables and shielded control cables. The contract value exceeds RMB 15.3 million, with deliveries scheduled from June 2025.
Wind farms require reliable medium-voltage cable systems to collect electricity from individual wind turbines and transmit it to the substation. The 35kV cable system must withstand outdoor and buried installation conditions, including moisture, temperature variations and mechanical stresses.
The project required multiple 35kV cable configurations with conductor cross-sections ranging from 3×120 mm² to 3×400 mm², together with low-voltage power cables and shielded control cables for different applications across the wind farm.
The project required matched cable accessories, including indoor and outdoor terminations, straight-through joints and related installation accessories, to support reliable cable system installation and connection.
The 35kV cables were specified with waterproof construction, including PE/DSTA/PE-W configurations, requiring appropriate cable construction and manufacturing controls for outdoor and buried installation conditions.
Complete technical documentation, including datasheets, test reports, material certificates and quality assurance records, was required to support EPC review and project acceptance.
Cables and accessories were supplied from China to the Laos project site, requiring export packaging, shipping coordination and delivery scheduling aligned with the construction program.
