22kV - 630kVA Cast Resin Dry Type Transformer, Three Phases, Power Distribution
General scope:
Application for power distribution system and large power plant, etc.
Executed standards
IEC60076-11, DIN42523, China GB, international IEC or industrial standards.
Parameters: Rated Voltage: 33kV.
Rated Capacity: 630kVA.
Advantage :
1.Self-extinguishing and inflaming retarding, 
2. Low losses, high efficiency
3. Compact structure and free maintainance.
4.High security, great overload capability to withstand short-circuit 110 % overload in sudden situation.
5.Low noise. Best for indoor opeartion.
Features & Advantages
1. Fire-proof and explosion-proof, pollution-free and no toxic gas being generated.
2. Excellent damp-proof performance, capable of working under 100% relative humidity and other harsh conditions, with no damp-removing measures needed.
3. Thin resin structure realizes chap-free surface and excellent heat-dispersion performance.
4. Nice appearance, small-size, less installation space occupation and low engineering cost.
Each transformer shall be equipped with four bi-directional wheels. These wheels shall be
adjustable for either transverse or longitudinal movement and equally spaced in both directions.
The undercarriage shall be sufficiently sturdy to permit the use of crowbars etc., place against it
during movement to the transformers final location.
The enclosure shall be fabricated from Galvanized Sheet Steel with minimum thickness of 2.3
mm and shall be self-supporting when assembled. The degree of protection against persons,
foreign objects and ingress of water shall be IP21 in accordance to IEC 60529.
