33kv Electrical Combination Prefabricated Compact Cubicle Power Distribution Transformer Substation
33kv Electrical Combination Prefabricated Compact Cubicle Power
Distribution Transformer Substation Introduction:
The needs of the wind power plant developed a special combination
of a series of wind power substation, the product will be issued
690V voltage electricity through wind generator step-up transformer
becomes 35KV or 10KV voltage level, the power grid into the system
or user to complete the task of wind power, wind power is the best
system of complementary products.
2.Features of 33kv Electrical Combination Prefabricated Compact Cubicle Power
Distribution Transformer Substation
A, energy-saving, no-load loss and load loss lower than similar
products, to maximize the protection of the full use of wind
energy.
B, safe, and reliable protection of personal safety, the use of
anti-theft box structure.
C, high-temperature, over-load operation capability, small,
compact, safe and convenient, can be used for ring terminals for
easy conversion.
D, environmental protection, lifetime without oil filter, oil
change, pollution.
3. 33kv Electrical Combination Prefabricated Compact Cubicle Power
Distribution Transformer Substation Normal environmental conditions
