The high voltage isolation transformer is flame retardant, explosion proof, no pollution to the environment.Insulation materials such as glass fiber winding coil have self-extinguishing characteristics, which will not produce electric arc due to short circuit, and resin will not produce toxic and harmful gases under high heat.


Product Introduction

1)High reliability,advanced level of performance,reasonable economical indicators.

2)The core joints are of stepped shape with 3steps,and the surface of the core is coated with cured paint to lower losses and noise.

3)The winding has novel structure and its oil passage is reasonable designed.Its newly designed insulation structure helps enhance its mechanical strength and the short circuit withstanding ability.

4)The oil tank is various types,all have good outlook.

Delivery time

Normally, if with MR or ABB tap changer, the max. Deliver time about 120 days after technical drawings confirmed, if with Chinese brand tap changer, max. 90 days for any capacity and voltage range transformer.

Packing

The transformer main body usually in nude, and the accessories are packed in plywood case with steel structure, it’s worthy for ocean transportation.

Transportation

Usually, the total weight under 45 tons, it’s available by kinds of container, above 45 tons, it’s available by bulk ship.

After service

Usually, we will dispatch experienced technicians to client’s installation site for the supervision service within 15 working days after getting official information.


FAQ

1.What are the other functions of ac reactors?

Maintain the power engineering electronic components of the drive organization ;Enhance power factor ; Avoid the power failure caused by the working voltage of the main switching power supply.

2.What is the function of the adapter?

The electronic power adapter that converts the alternating current into alternating current is usually embedded in the indoor space. Usually, the adapter has a large volume. The small-volume equipment is all external, so as to save indoor space, and the second is easy to replace.

3.What is the reason of abnormal noise on transformer fire floor?

AC current working voltage is not stable, integrated ic damage, turn-to-turn short circuit fault, component damage, etc.


Latest News

The core of the coil core transformer is one overall, the core is not knocked out, and the electromagnetic coil cannot be taken out. It is difficult to remove the whole core and the electromagnetic coil. Since the weight of each 1OOKvA transformer is more than 350kg, the net weight of the 150kVA transformer is 63Okg. It is not easy to put silicon steel sheets and copper core wires. The items of value are separated. Therefore, the winding core transformer has good anti-theft performance.
