TSTY Participated in 10 Substations Transformation in Thailand

September 24, 2020

On April 12, 2016, 10 substation transformation projects in Thailand participated by TSTY have all been put into operation. The smooth operation of the project has further accumulated a good reputation for TSTY's products and services in the Thai market.

TSTY Participated in 10 Substations Transformation in Thailand

The substation adopts our company's most competitive S11 oil-immersed transformer, ZGS box-type substation and series of high and low voltage switch cabinets.

TSTY’s S11 series fully sealed oil-immersed power transformer has the advantages of low loss, low noise and high efficiency, which can achieve good energy-saving effects and reduce pollution;

Compared with ordinary oil-immersed transformers, fully sealed transformers eliminate the oil conservator. The change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated oil tank. The transformer is isolated from the air to prevent and slow down the deterioration of oil and insulation aging so as to enhance operational reliability, and maintain normal operation without maintenance.

The transformer core is laminated with imported cold-rolled silicon steel sheets, which greatly reduces the no-load loss and no-load current. The core is bound to ensure the tightness of the core and reduce noise. High and low voltage windings are made of oxygen-free copper, and low voltage windings of 500kVA and below adopt double-layer cylindrical structure. 630kVA and above adopt double helix or four helix structure, high voltage winding adopts multilayer cylindrical structure.


The transformer connection group uses Dyn11 to reduce the impact of harmonics on the power grid and improve the quality of power supply. And it as a fully sealed structure, which prolongs the service life, does not require hanging cores and maintenance. The measured noise value is lower than the standard. After this series of transformers have been transported normally, the relevant parts can be installed without core inspection, and they can be put into operation once the acceptance test is qualified.

TSTY Substations Transformation in Thailand


TSTY’s box-type substation puts the transformer body, high voltage load switch, fuse and other components together in the transformer tank. Because of the immersion in oil, the volume of the components is greatly reduced, the structure is more compact, and the installation is convenient and flexible. It is fully insulated, and has fully sealed structure, safe and reliable, easy to operate, and maintenance-free.

TSTY’s 10 substations of the project are distributed around Bangkok, the capital of Thailand, providing a solid guarantee for the stability of the Bangkok power grid.
