250KVA Single Phase Pad Mount Transformer Distribution System 4160v
240v Outdoor 304 Stainless Steel
Single phase pad mounted transformer is oil-immersed distribution
transformer.The traditional transformer is designed in a box-type
shell. It has the characteristics of small size, light weight, low
noise, low loss, safety and reliability.It is widely used in
residential quarters, commercial centers, hospitals, parks,
schools, etc.Single phase pad mounted transformers are self-cooled,
available in loop or radial feed, and are dead front,Meet or
exceeds ANSI /CSA/IEEE standards.
Performance Characteristic
1)Combination Transformer Substation, The top of cabinet is with
steel plate clamp rock wool structure which has ventilation duct,
can reduce the solar radiation effectively and ensure the heat
dissipation.
2)The surface of whole cabinet shell sprays special primer and
paint which has strong anti-corrosion ability.
3)The inside can be divided into high voltage chamber, transformer
chamber and low voltage chamber respectively.
4) Also it is be equipped with temperature control automatic
exhaust device to ensure the temperature range.
5)Each unit has impeccable control, charged display and lighting
system.
6)The apparatus equipment are accord with IP33 protection
requirement, have reasonable design,structure and technology, with
good quality and easy maintenance.
