30-31500 kva three phase transformer

30-31500 kva three phase transformer product description:

30-31500 kva three phase transformers guarantee dielectric strength to withstand impulse voltage thanks to high-technology design which ensures low capacitance between winding and the ground and proper coordination of insulating material and solves creepage problem.

Reliability of three phase transformers manufactured by us is excellent because of winding and tank design which distributes mechanical force evenly in case of short circuit and supports short-circuit strength effectively.

30-31500 kva three phase transformer production display:

30-31500 kva three phase transformer windings are composed of two parts, namely, a conductor and insulation material. For the conductor, we use high grade electrolytic copper or aluminium. Our Oil Immersed Transformers obtain high thermal capacity with the use of Epoxy coated Insuldur Kraft Paper, which has higher short time overload capacity than any other Kraft paper type.

30-31500 kva three phase transformer core design is essential because it determines the transformer’s efficiency and noise level. For high dimensional accuracy, the core cutting processing of us is controlled by a computerized system. By Step-Lap core stacking, Our Oil Immersed Transformers attain to optimal characteristics for each customer.

Three phase transformer will be furnished with panel or corrugated radiators assuring that the temperature rise of the windings or oil will not exceed their specified limit when the transformer continuously operates at the rated full load.

30-31500 kva three phase transformer FAQ:

1. Can the price be negotiated?

A: Yes, the price is negotiable. It can be changed according to your quantity or package.

2. What is the capacity of your three phase transformer?

A: We can supply three phase transformers with a capacity below 31500 kva.

3. What is the altitude of your transformer used?

A: We are able to supply ordinary three phase transformers(The altitude is less than 1000m) and plateau transformers(The altitude is greater than 1000m) according to your requirements.

4. What is the difference between copper core and aluminum core of three phase transformer?

A: The mechanical strength of aluminum coil is worse than that of copper coil;

The thermal stability of aluminum wire is poor, so aluminum wire ring is easy to be burned;

The production cost of aluminum wire is lower than that of copper wire.

5. What is the connection mode of your three phase transformer?

A: We mainly produce Dyn11 and Yyn0 three phase transformers, which can be designed and manufactured according to your requirements.

30-31500 kva three phase transformer detection and storage:

ZTELEC company was founded in 1958, as a national enterprise offering electric insulation systems and components for national motor and power companies, military and aviation enterprises. Nearly 60 years production and R&D experience, developed to now Zhongtian group mainly provides insulation materials, special materials, power transmission and transformation whole set, transformers, enameled copper wire etc high-end products.

Ztelec insists on testing every production link, and each 30-31500 kva three phase transformer is factory tested. Guarantee the safety of each customer’s property.

In order to ensure that each 30-31500 kva three phase transformer can be protected from secondary pollution after production, we will put a moisture-proof dust bag on each three phase transformer. The transformer will be transported to a constant temperature and moisture-proof warehouse for storage.
