The pre-fabricated substation consists of an HV switch, transformer, LV switch, auxiliary equipment, connection parts, etc. as a set of booster equipment. The type of transformer can use an oil-immersed transformer or a dry-type transformer. This product is mainly used for outdoor and booster place with non-excitation pressure regulators.
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.
Application: Power grid, solar power plant, wind power plant, hydro power plant, nuclear power plant, infrastructure, real estate, etc…
After-sales Service: We have a professional aftersales engineer team, each one aftersales engineer has more than 3 years’ experience. And we also have localized technical backup to offer timely support in Malaysia, South Africa, Egypt, Dubai, UAE, Brazil.
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.
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 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.
