Product Description

This pole mounted distribution transformer 200kva mainly adopts a three phase design. The conventional rated voltage combinations include 10/0.4kV, 11/0.4kV, 11/0.433kV, 22/0.433kV, 33/0.4kV, etc., covering various options suitable for different regional power grids. The equipment is standardly equipped with no excited voltage regulation, with a voltage regulation range of ±5% or ±2×2.5%. The connection group can be selected as Dyn11 or Yyn0.

Under 50Hz conditions, the rated current on the 10kV high voltage side is approximately 11.55A, on the 11kV high voltage side it is approximately 10.50A, and the rated current on the 0.4kV low voltage side is approximately 288.68A. The conventional short circuit impedance is 4%. At the same time, it can be customized according to user requirements for voltage, connection group, etc. Energy efficiency can be selected from ordinary loss, low loss, and amorphous alloy series products.

Advantages:

Are there any differences between the pole mounted distribution transformer 200kva and the pad mounted type?

1.The pole mounted distribution transformer 200kva is fixed on the utility pole, at a certain height above the ground. It does not occupy valuable land resources and has little impact on the ground space. The pad mounted transformer is placed on a concrete base, which requires a certain area.

2.Because it is suspended in the air, people and animals are less likely to come into contact with it, making it relatively safer. However, even so, there is no need to be overly nervous when passing by. Maintaining a normal distance is sufficient. The pad mounted transformer is installed in a relatively concealed manner.

3.Each single transformer has a limited power supply range, typically ranging from 5 kVA to 167 kVA. It is mainly used to supply power to a small number of users on a single line. However, the pad mounted transformer has a relatively larger capacity, ranging from 75 kVA to 3000 kVA.

4.Compared to the equipment buried underground, this overhead installation method has lower material costs and construction difficulty. It is a very economical and practical power supply solution.

5.The pole mounted distribution transformer 200kva is usually a cylindrical oil tank, filled with cooling oil for insulation and heat dissipation. The top is the high voltage connection terminal, and the bottom is the low voltage connection terminal. The design is very compact. To ensure safety, it often integrates lightning arresters and fuses to prevent lightning strikes and short circuits.
