Hermetically-sealed amorphous alloy distribution

transformer adopts the amorphous alloy iron as its

magnetic material. It is eco-friendly and energy

conservation, which complies with the standard of

China energy conservation outlineissued by National

Economic Committee.

Product introduction

b. JB/T10318-2002 Technical parameters and requirements for hermetically-sealed and oil-immersed amorphous alloy

distribution transformer

Applicable standards

a. Iron's magnetic material adopts amorphous alloy, which consists of materials such as iron and boron, etc.

b. The iron structure of amorphous alloy transformer adopts three phases and five columns.c. This kind of transformer has similar body assemblystructure of oil tank, and protection devices with hermetical oil-

immersed transformer.

d. This kind of transformer has same load-loss with S9 series, but the no-load loss of SBH-15 transformers are decreased

by approx. 75% by comparing with S9 series. It can save electricity and decrease the loss cost. Generally, we can take back

the extra investment in four years compared with the silicon-steel iron transformer.

e. Under the normal operation, it does not need to change oil, which decreases the transformer's maintenance cost and

prolongs the service life.

Production introduction

1. A multilayer cylinder structure is used for all high voltage windings in order to improve the voltage impulse distribution of

windings.

2. For the capacity range of low voltage windings is from 30kVA to 2000kVA, the cylinder type or spiral structure is used to

ensure the high mechanical strength, ampere lure distribution, and excellent short-circuits proof performance.

3. The securing structure is set in the transformer body, which is used for ensuring that no displacement will occur during the

transportation; meanwhile, the turnbuckles are mounted in fasteners, which is for assuring that fasteners will not be loose

during the long term operation.

4. Corrugated tanks are used in the transformer for replacing the conservator. The tank enclosure and rim are completely

sealed by welding or bolting up, which prolongs the service life of transformer oil.

5. The transformer surface are painted with primer and finish coats after degreasing, derusting, and phosphorizing; which can

meet the special operation requirements in metallurgic and petrochemical industries, as well as, in moist and dirty places.

6. The press relief valves, signal thermometers, and gas relays are equipped in the oil tank of hermetically sealed transformer

in order to the standard requirements for safe operation. The transformers are attractive and competitive due to the compact

shape, excellent design, and maintenance-free.

The product conforms to the technical parameters

and requirements of China National Standard GB1094

and GB/T6451, and a series of significant innovation is

applied in aspects of material, design and structure. It

has the features of high efficiency and low loss. It can

save a lot of operation cost, and the social benefits are

very significant. In conclusion, it is a nationally promoted

new product and it is deeply favored by customers.

Installation type: indoor/outdoor type

Ambient temperature: -25+40

Altitude: 1000m

Installation site: in places without corrosive gases

and obvious dusts.


1. The features of this product are high efficiency and low loss. It can save a lot of operation cost, and the social benefits are

very significant.

2. The iron cores are made of the imported high-conduction magnetism, cold-roll, and grain-oriented silicon-steel sheets. The

iron cores and windings adopt the vacuum drying and vacuum oil-filling processes, which make the internal moisture down

to the very low level.

3. The conservator is hermetically sealed, which make the internal running oil to insolate with oxygen and moisture efficiently.

4. The above features guarantee the transformer does not need to replace the oil during the normal operation, greatly

decrease the maintenance cost, and prolong the service life.

The dry-type transformers are casted with epoxy

resin, which are made of high quality materials by

means of a strict process with advanced production

and testing devices. The product features high reliability

and long service life. In accordance with different

operation environment, it can be equipped with different

protection casings or without casing. It can replace the

oil-immersed transformer and be used in the high

buildings, business centers, airports, tunnels, chemical

plants, nuclear power stations and watercrafts etc.


GB6450-1986 Dry-type power transformer

GB4208-1993 Casing protection grade (IP code)

GB/T10228-1997 Technical parameters and requirements for dry-type power transformer


1) Altitude should not be over 1000m: indoor type

2) Highest ambient temperature should not over: 40; Highest daily average should not over temperature: 30

3) Highest annual average temperature should not over 20, lowest temperature should not below -5

We can provide transformer operated in special conditions according to user's requirement.

Normal service conditions

1. The product is safe, fire-proof, pollution free, and can be used in the load center directly.

2. High mechanical strength, strong short-circuit proof capacity, small partial discharge, excellent thermal stability, high

reliability, and long service life.

3. Low loss, low noise, energy saving and maintenance free.

4. Excellent heat dissipation, great overload capacity and a larger operating capacity is available when ONAF is applied.

5. Good humidity resistance, it's suitable for operating in the highly humid and harsh environment.

6. An intelligent signal and temperature control system is adopted, which can automatically monitor and display all working

temperature of the three-phase windings. The blowing fan can give an alarm, switch on and off automatically and conduct

tripping operation to protect the transformer.

7. Due to the structure is compact and weight is light, it can save space and decrease the cost of installation.

1. Excellent heat dissipation, long thermal life, good overload capacity, without forced air-cooling under a long-term 120%

overload and IP45 condition. It can operate for a long time at full load.

2. Extremely high safety fire resistance performance, smoke-free while burning under a temperature as high as 800.

3. Extremely high thermal shock resistance capacity.

4. 100% water-proof, excellent moisture -proof.

5. Unique winding structure and field strength calculation makes partial discharge impossible.

6. Low loss and significant energy saving effect. Compared with SC9 series of dry-type transformers, the no-load loss falls

10% and load loss falls 5% in average.

7. The insulation material and copper conductor can be dismantled easily and recycled after the service life. Therefore, no

pollution will occur.

transformer


Installation type: indoor/outdoor type

Ambient temperature: -25+40

Altitude: 1000m

Humidity: daily average value 95%, monthly average value 90%

Installation site: in places without corrosive gases, obvious dusts and water-vapour; the gradient is no more than 3% and

no fierce shock.

Normal service conditions

1. Compare with type "9" transformer, the product's no-load loss is reduced by 30% and thus the average annual operating

costs can be reduced by 20.03%.

2. The transformer body, high voltage load switch fuses and no-excitation tapping switches are all put into the fully-sealed

oil tank, which make good use of the space. Therefore, the overall size of the product is only 1/3 of that of the similar product.

3. The plug-in and out cable connection is easy for operation.

4. An obstacle protection is of two-stage fuses structure (backup current-limiting fuse and plug-in type fuse) which ensures

a safe and flexible operation and more convenient for replacing of fuse.

5. The oil tank is fully-sealed, in which the oil is totally isolated from the outside. No leakage and maintenance free.

6. Excellent short-circuit proof capacity and high reliability.
