Product Description:

.jpgJBK1 series transformer is applicable to AC 50~60HZ circuit,rated output voltage no more than 1140V,and rated input voltage no more than 1140V,which could be widely used in the control power supply of machine tools,mechanical equipments,local lighting ,signal lamps and others.

.jpgIt has characteristics of excellent performance,reliable operation,low energy consumption,small volume,safe wiring and wide application,and as it can work for a long term under rated load ,it is an ideal variable voltage power supply.








We were established in November of 1994.Until now,It has been developed to be a professional transformer manufacturer after 20 years' development,who integrates R&D,producing and marketing,Meanwhile,Xinping is the earliest transformer manufacturer which gets CQC certificate in China.

The main products of Xinping include different kinds of transformers,such as EI transformer,encapsulated transformer,switch power supply transformer,inductance transformer,BK&JBK transformer,toroidal transformer,intelligent servo transformer,three-phase dry type transformer,QZB transformer,special transformer and others.

It is located in Dezhou,Shandong Province which is the domestic key traffic hub in China,(In 2015,Dehou has been regarded as the cooperation development city with Beijing,Tianjin and Hebei).Now there are more than 400 employees in the company,15% employees are special technicians.We covers an area of about 53,000 square meter,and the floor area is more than 30000 square meter.

Xinping does a lot of tests during design,developing and the application of raw material and uses high quality raw material finally.So the transformer has the advantages of low no-load loss,high efficiency and low temperature rise.It has been widely used in househole appliances,intelligent meters,solar meters,automatic equipment,special equipment and others.

In the process of manufacturing and business,We always sticks to the principle of honoring contract,keeping credit,complying with business ethics and seeking the perfect quality.Being the leader of transformers and electronic components industry is the development goal of Xinping.Comparing price under the same quality and comparing quality&service under the same price is the business concept of Xinping.Devoting to your requirment,We will supply you excellent service from products concept to designing ,sample making,confirmation,producing,testing and delicering.Wewoule like to cooperate with you and build a bright future together.

Q:Transformers have any way of cooling
According to the requirements of the transformer selection guide, the choice of cooling method is recommended as follows: 1, oil leaching from the cold    31500kVA and below, 35kV and below products;    50000kVA and below, 110kV products. 2, oil-immersed air-cooled    12500kVA ~ 63000kVA, 35kV ~ 110kV products;    75000kVA below, 110kV products;    40000kVA and below, 220kV products. 3, forced oil circulation air-cooled    50000 ~ 90000kVA, 220kV products. 4, forced oil circulation water cooling    General hydropower plant up and down 220kV and above, 60MVA and above products used. 5, forced to guide the oil circulation air cooling or water cooling (ODAF or ODWF)      75000kVA and above, 110kV products;    120000kVA and above, 220kV products;    330kV level and 500kV grade products.
Q:Which is good for the transformer?
and other electrical equipment. Product design novel, small size, handsome in appearance, with low loss, low noise, impact resistance and so on. Widely used in industrial and mining enterprises, textile machinery, printing and packaging, petrochemical, schools, shopping malls, elevators, post and telecommunications, medical machinery and other needs of the normal voltage guarantee occasions.
Q:What is the reason why the dry transformer is loud
500kva below the dry-type transformer noise 56 to 58 dB or so, 630kva above 62 to 65 dB or so! This is our factory data. The dry-type transformer sound is great. Big like cattle called the same, because the core is loose!
Q:Is the transformer output DC or AC?
Is the exchange, after the diode rectifier into a DC.
Q:50KVA transformer each phase current maximum band
Normal current does not exceed 72A per phase current. Of course, in the event of an accident or to strengthen the transformer cooling can be short-term overload operation.
Q:What does S11-M-500/10 transformer mean?
The first floor has been very accurate to answer my answer that M is sealed!
Q:Rules for the operation of cooling devices for oil - cooled transformers
A, cooler should take their own independent dual power supply, and can automatically switch, when the work of power failure, automatically put into standby power, and issued a sound signal;  B, the transformer upper oil temperature reaches 55 ℃ or the current reaches 70% of the rated value, the auxiliary cooler automatically input;
Q:Transformer 1KVA can load how much security, how to calculate the formula
You only give a parameter, that is, KVA, you have to give two dollars to count
Q:Transformer winding maximum temperature at?
National standard "dry-type transformers" GB6450-1986 on the dry-type transformer temperature limit to make the provisions. 1, the dry-type transformer coil, when the use of A-class insulation material, the ultimate operating temperature of 105 ℃, the maximum temperature rise should be less than 60 ℃; when the use of E-class insulation material, the limit operating temperature at 120 ℃ , The maximum temperature rise should be less than 75 ℃; when using B-class insulation material, the extreme working temperature at 130 ℃, the maximum temperature rise should be less than 80 ℃; when using F-class insulation material, the limit operating temperature at 155 ℃ , The maximum temperature rise should be less than 100 ℃; when the use of H-class insulation material, the limit operating temperature at 180 ℃, the maximum temperature rise should be less than 125 ℃; when using C-class insulation material, the extreme working temperature at 220 ℃ , The maximum temperature rise should be less than 150 ℃.
Q:What is the difference between AC transformers and DC transformers?
Transformer is made of electromagnetic induction principle can change the voltage of the equipment. Transformer has a core and coil composition. Transformer coil sub-primary and secondary coil. In the primary coil in the AC power. Transformer core to produce alternating The secondary coil senses the same alternating current as the primary frequency, and the number of turns of the transformer coil is equal to the voltage ratio, for example, the primary coil of a transformer is 880. The secondary is 88. At the primary access 220V. It will output 22V AC voltage. Transformer can not only buck can also be boosted. Long-distance transmission are generally used to increase the voltage transformer. Reuse in the power transformer to the voltage we need
