Overview: (low loss type three-phase dry type safety isolating transformer (F class 155 insulation grade)

The transformer is the device transform AC voltage, current and impedance, when there is communication through the primary coil current, the core (or core) will be generated in the exchange flux, the secondary coil induces a voltage (or current). With the continuous development of transformer industry, more and more companies use transformers, more and more enterprises enter into the transformer industry, transformer from the core (or core) and the coil of the coil is two or more than two windings, which then called the primary coil winding power, the rest is called the secondary coil windings.

Transformer is the main component of all kinds of power supply and electrical equipment. The isolation transformer is composed of cylindrical winding and laminated iron core. The core is made of new high quality high silicon silicon steel lamination and fully inclined joint. The company adopts advanced manufacturing technology, has imported Spanish winding machine and a full set of vacuum pressure impregnation equipment; winding adopts the whole winding method; vacuum impregnation of transformer, so that the transformer insulation level reached F or H class. The output and input voltage of the transformer can be designed according to the customer's requirement. There are many kinds of specifications, such as single phase, three-phase or multiple input and output.

Material description of transformer:

Iron core

The new high-quality high silicon steel sheet, the main material is 0.35 thick H18, H14, H12, Z11 quality silicon steel sheet, we according to customer requirements and use conditions, choose the most suitable materials, so that the transformer performance design to achieve the best. (conventional material is new quality silicon steel sheet).

Wire rod

By PEW, UEW, EIW, SEIW, FEAI and enameled glass envelope, high temperature grade F (155 C), H (180 C), HC (200 c), C (220 C). (conventional temperature tolerance grade F grade 155).

 Insulating material

High temperature resistant insulating paper is used as insulating material. It has high temperature insulation, flame retardancy and moisture resistance.

Wiring terminal row

Low power use terminal row, beautiful appearance, excellent pressure resistance, temperature resistance, flame retardant performance. High power high quality copper.

 Iron foot

Mainly uses the numerical control bending cold tie board, has the multicolored (golden), the blue zinc (Yin Bai), the white zinc (ivory white), the surface anode treatment (black) and so on the environmental protection galvanization may choose.

Cooling method

Temperature controlled air cooling

1, scientific and reasonable design, the voltage fluctuation rate is controlled within 1~1.5%.

2, the use of high-quality new silicon steel sheet system, effectively reduce iron loss, improve efficiency.

3, using high temperature resistant high quality wire system, the loss of its own to the lowest, greatly improve the efficacy.

4, using H class insulation, high temperature resistant insulation material, improve the high pressure strength, insulation grade, extend the service life.

5, high efficiency design, more than 98%.

6, patent appearance design, beautiful, novel, large power density, small size, high space utilization.
7. according to the product structure is divided into open type and door type two, protection type is the use of the steel plate box shell, inside the transformer box shell, shell box outside the outlet holes for the installation of power lines. If necessary, the voltmeter, ammeter, temperature control alarm system and steering wheel can be added according to the user's requirements so as to move.

Use condition:

1 for altitude: 3000m
2 environmental temperature: -15 ~ +45
3 relative humidity: less than 90%
4 the installation site shall have no gas, steam, chemical deposition, dirt, conductive dust and other explosive, flammable and easily corrosive substances that seriously affect the insulation strength of the transformer.

Order requirement:

When purchasing a product, please specify the following points:

1. Basic type, specification, capacity and quantity of transformer;

2. Primary and secondary voltage of transformer;

3, when the secondary voltage is supplied, it is better to provide the capacity allocation of each output voltage;

4, the outline and installation size are for reference only. If the required size needs to be changed, it must be explained when ordering.

Note: if the user has special requirements, the company can design and manufacture for it.
