1. Complete functions and high reliability
Capable of cutting off short-circuit current and load current, thus providing all-around protection for the transformer.
Multiple power supply methods are available for the HV sides, 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 substations.
Less installation space: only one-third of space is required.
Quick delivery: the substation could be delivered within one month.
3. High reliability
A hermetically sealed structure is adopted and the enclosure is reliably grounded, with no need for insulation distance and sufficiently ensuring the operator’s personal safety.
A 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 the “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
6. Flexible structure
Multiple types of structures are available for customer selection, with sub-assemblies arranged in different layouts, thus satisfying the customer’s special requirements.

Construction:

Transformer Core:
1.The core is made of high-quality grain-oriented cold-rolled silicon steel of high magnetic conductivity, by using 45°five-stepping all-leaning lamination way to laminate. So the no-load losses and the no-load current are reduced efficiently.

Transformer Windings:

LV windings:
1. LV winding is manufactured with a high-quality foil conductor or copper wire, and the ampere-turn is balanceable. The additional loss is low and the ability of anti-short is improved.
2. Oil drains of heat dispersion are scientifically used in the winding, and the surface of heat dissipation is increased, so the temperatures are reduced and the ability to over-load is improved.
HV windings:
HV winding is manufactured with high-quality copper wire and an excellent design structure. It improves the distribution of electric filed. With lighting impulse analysis, the ability of anti-lighting impulse has been improved.

Workshop:

Established in 1958, located in Guangzhou City, Pearl Electric Co., Ltd is one of the most prominent power transformer manufacturers in China which design, produce and supply power transformers in domestic and abroad with almost 660 employees, more than 260 sets of specialized manufacturing equipment.
Pearl Electric is Top brand in China for Class 1E dry type transformer of nuclear power plant application and industrial-leader for new energy application substation transformer and energy conservation transformer, covering an area of 100,000 m2 among more than 70,000 m2 of modern factory workshop.
