200 kva transformer ultimate purchasing guide

Reference to a 200 kva transformer, it will think about a 200 kva power distribution transformer. It use to transfer voltages between two circuit without to change the power. A 200 kva transformer is a widely used to industrial, residential and commercial electricity demands.

Conso Electrical Science and Technology Co., Ltd is one of the professional manufacturer to produce 10 kv to 35 kv 200 kva distribution transformer and 200 kva compact substation. Conso Electrical produce 200 kva transformers according to the customized requirement from clients. That is to say, Conso Electrical sell brand new 200 kva transformers. In Conso Electrical, each 200 kva transformers will have a series of factory test, until it is ready to delivery.

What is the type of a 200 kva transformer could have?

In Conso Electrical, it is the major service to clients that to produce 200 kva three phase oil immersed transformers, 200 kva three phase cast resin transformers and 200 kva pad mounted transformers. Meanwhile, Conso Electrical also produce 200 kva compact substations and 200 kva single phase transformers.

What is the difference between a 200 kva transformer and a 200 kW generator?

To figure this question, it is necessary to clarify the meaning of the kVa and the kW. The kVa is the unit of apparent power and the kW is the unit of active power. the apparent power is combined by the active power and the reactive power.

However in most power supply system, the generator plays the role of backup power, such as in a hospital, school, and factory, because the costs of running and maintaining a generator is much higher than a distribution transformer.

How much active power could a 200 kva transformer supply?

The 200 kva is the total power of a 200 kva transformer could supply. However, it needs to multiple the power factor on the total power to get the active power. In most countries and areas, the power factor shall be greater than 0.9 to keep the power grid runs efficiently. Thus, a 200 kva transformer could supply 180 kW active power when in 100% loading.

By the way, the actual service life cannot reach to the designed service life if a 200 kva transformer 100% loaded all the service life. The suitable loading rate is 50% to 80%. it could make the energy consumption within a lower level.

The Main factor to impact the costs of a 200 kva transformer.

Conso Electrical provides the customized service to manufacture 200 kva transformers. We promise to offer a budget friendly quotation to our clients. However, the costs of a 200 kva oil immersed transformer would be various among different technical requirement. three factors will impact the material costs mostly.

Firstly, The average temperature and the installation altitude are the main factors to impact the costs. It will be reflected in the specification of the temperature rise. The high requirement of environment condition will have a lower value of temperature rise, because the sum of temperature rise (winding average) and local temperature cannot be greater than 105℃.

Secondly, it is the transformer losses. The lower transformer losses will have a higher material costs. A higher transformer losses will create more heat to drop the operation efficiency.

Additional, it is the winding material. The current price of copper is higher than aluminum. Thus, the costs of a copper transformer is higher than a aluminum transformer about 40% to 65%. most of clients prefer to purchasing 200 kva copper transformer as it bring out a better performance. However, the performance is same between a copper cast resin transformer and an aluminum cast resin transformer.  

How much does a 200 kva transformer cost?

In most of cases, a 200 kva transformer costs about $ 1800 to $ 9000. the price is variable because of the current price of components and the different requirement. Take a 10/0.4 kv three phase 200 kva transformer as an example:

1. A 200 kva oil immersed transformer might costs $ 3000;

2. A 200 kva dry type transformer might costs $ 3500;

3. A 200 kva pad mounted transformer might costs $6500.

How do I choose a suitable 200 kva transformer?

To pick a suitable 200 kva transformer, we need to know the strength and weakness among 200 kva onan transformer, 200 kva cast resin dry type transformer and 200 kva pad mounted transformer.

1. A 200 kva onan transformer is more popular than 200 kva cast resin dry type transformer and 200 kva pad mounted transformer. Firstly, the 200 kva onan transformer has a lower material costs. Secondly, the 200 kva onan transformer could be mounted on the electricity pole to supply power to a community. However, the mineral oil might damage to the local soil structure, if the operation is not correct in maintenance. 

2. A 200 kva cast resin dry type transformer is widely used in the place which has the serious requirement on fire protection, such as metro station, office building and supper market. It does not like a oil immersed transformer. The insulation material is flame retardant and eco-friendly. Meanwhile, the maintenance costs is lower than a 200 kva oil immersed transformer. However, the 200 kva cast resin transformer is designed as indoor usage, as the protection level of transformer body is IP00.

3. A 200 kva pad mounted transformer is combined by transformer body, primary voltage control unit, secondary voltage unit control unit and capacity bank unit. Normally, the transformer body is a oil immersed transformer. A pad mounted transformer is one of the best solution to a factory, or a city park.

How to select a capable 200 kva transformer manufacturer?

1. To check the company qualification of the 200 kva transformer manufacturer. The following certification has to be show up to clients:

a.         business licence;

b.         Type test report from the third party;

c.         ISO 9001 14001 and 45001 certification.

2. To check the producing and testing equipment of the 200 kva transformer manufacturer. The clients could ask 200 kva transformer manufacturer to send the related photos or the special value-added invoice.

3. To ask the 200 kva transformer manufacturer attach technical agreement or technical requirement document with the contract.

Conso Electrical Science and Technology Co., Ltd is one of the best manufacturers to produce 10 kV to 35 kV distribution transformers, compact substation and vacuum circuit breaker. The company mainly supplies 200 kva transformers to power grid corporation and the 200 kva compact substation to urban construction corporation. Conso Electrical has an experienced team to design and produce 200 kva transformers. We aim to build a long term relationship with our clients.
