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.
