Functions and Advantages:
1. Complete functions and high reliability
Capable of cutting off short-circuit current and load current, thus to provide all-round protection for the transformer.
Multiple power supply methods are available for HV side, such as looped network, dual-power supply, terminal and HV measurement.
Having all functions of traditional civil transformer substation.
2. Less investment, less installation space occupation and quick delivery
Less investment: low cost compared with traditional civil transformer substation.
Less installation space: only one third of space is required.
Quick delivery: the substation could be delivered within one month.
3. High reliability
Hermetically sealed structure is adopted and the enclosure is reliably grounded, with no need for insulation distance and sufficiently ensuring operator's personal safety.
Protective fence is added for the transformer room, to avoid accidental entering into the transformer room.
4. Reliable temperature rise control and excellent heat dispersion performance
The ventilation structure of "Chimney effect" is adopted for the enclosure and optimized to enable the product with higher heat dispersion performance. The enclosure's temperature rising control measures meet the highest 10K-class standards specified in GB/T 17467-1998 and IEC1330.
5. Excellent environment adaptability
Multiple types of enclosure are available for customer's selection, for example, common steel plate enclosure, composite board enclosure, stainless steel enclosure and "Three-proof" enclosure.
The enclosure made of composite board has the following advantages:
a. High mechanical strength for anti-bending, anti-shocking and anti-pulling.
b. High capability of anti-insolation, anti-radiation and heat insulation.
c. Excellent performance for frostbite-prevention, cracking-proof and heat-insulation.
d. Damp-proof and self-extinguishing. No condensation will happen at sudden temperature drop or rise.
e. "All-weather" operation.
f. Nice appearance and harmonic with the environment.
6. Flexible structure
Multiple type of structures are available for customer's selection, with sub-assemblies arranged in different layout, thus to satisfy customer's special requirement.
