Three-phase pad-mounted transformer

SH Power offers full life-cycle support for its transformers,covering solution design, model optimization, and on-site commissioning—all handled by our experienced technical team. We provide tailor-made solutions for various applications to ensure efficient operation and maximize energy savings.

Description

Three-phase pad-mounted transformers are installed in locked steel cabinets on concrete pads and are used in conjunction with underground distribution lines at the point of supply. One transformer can serve a large building or many homes. Technical
Transformer Type:	Three-phase pad-mounted transformer
Transformer Capacity(kVA):	15-5000
Primary Voltage(V):	35000
Secondary Voltage(V):	—
Frequency (Hz):	50~60
Winding Material:	Aluminum,Iron
Anti-corrosion Grade:	C5+

Product functions

Three-phase pad-mounted transformers have rated AC frequency: 50Hz/60Hz; maximum operating voltage: 35kV; capacity: approximately 15kVA ~ 5000kVA.
Compact, safe and reliable structure: the transformer (main part) is enclosed with high-voltage control and protection components (e.g. high-voltage load switches and fuses) in the transformer oil tank.
Small-sized, only about 1/3 of European box transformers of the same capacity, thus covering a smaller area.
Excellent heat dissipation and strong operating capabilities under overload.
Simple configuration of high-and low-voltage units, low cost, and high economic applicability.
Fully enclosed oil tank without conservator, reducing the workload of regular maintenance and observation.
Optical fully shielded and insulated elbow arrester : it can be directly installed on the two-way sleeve joint, without occupying any area.
High voltage quality, low noise and excellent lightning protection performance, without neutral drift or tank heating.
Anti-corrosion and painted tank surface, applicable to harsh conditions, such as storms, rain, snow, and pollution-intensive areas.
