Power Supply Power supply modes
The power supply mode is double circuit feeding. TEDA can provide
dedicated power supply
lines to consumers who consume
large amount of electricity or have special demands.
Electricity charges vary according to different power
supply scenarios.
Power supply capacity
TEDA has already in place a power grid network of three
different voltage levels: 110KV, 35KV
and 10 KV. The
power supply capability of the grid is 550,000 KVA, and
the annual capacity of
1.5 billion kw. TEDA has 1 220KV
transformer station, 3 110-KV transformer stations, 11
35-
KV transformer stations, and 28 10-KV transformer
stations and transformer boxes.
Technical specifications
The power supply variation is 50HZ±0.2HZ. Consumer
transformers with the total capacity
exceeding 100KVA
are fed by 10-KV. Low-voltage is possible if conditions
permit. Consumer
transformers with the total capacity
exceeding 3,000-KVA are fed by 35-KA. 10-KV is also
possible, subject to actual conditions and technical
analysis.
For 35KV consumers, the voltage variance does not exceed
±5% of the approved voltage. For
10KV consumers, the
voltage variance does not exceed ±7% of the approved
voltage. For low
voltage lighting, the voltage variance
is between +5% and 10% of the approved voltage.
