333kva Single Phase Pad Mounted Distribution Transformers 34500grdy
To 240v Meets Ansi Ieee Standards
Single-phase base transformers have the characteristics of small
size, light weight, safety and reliability. The single-phase base
transformers we specialize in fully meet or even exceed the
standards of ANSI/IEEE and DOE CSA, with a capacity of
10KVA-250KVA. We independently invest in the production of key
components such as oil tanks and cores, with a monthly delivery
capacity of more than 600 units, and can be delivered quickly
within 35 days.
product structure
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.
