High Efficency Dry Type Transformer Made With Epoxy Resin 2500 Kva-50 Kva​

Dry Type Transformer Advantages:

Cast resin dry type transformer, eco-friendly, high efficiency.

  1. Low loss, low noise, low partial discharge, high reliability. Best for general users , such as hospital, tower, hotel, etc.
  2. Strong capability with anti-short circuit, high anti-lightning impulse capability.
  3. HV coil is vacuum casted with epoxy resin with pressure, capabilities for better the cast without pressure. Subject to customer need, both HV and LV coil are fully vacuumed.
  4. Simulating analysis being used in the core model, the resonance can be avoided and the noise is reduced. Simulation calculation and analysis of lighting impulse wave are applied to the HV Coils; anti-lighting impulse capability is improved.

Accessories : IP protective enclosure


The standard transformers produced by our company are without the case and their protection level is IP20.We can also provide IP30 or IP40 if you require.The case can be made by common steel plates,stainless steel plants or aluminium alloy and can be acid-washed,parkerised and powder-painted.


Accessories :Temperature controller

The temperature control displays are installed on the low voltage side of the case ,which are reliable and convenient for users to check.

Installation

1 Before equipment installation, please first refer to the following materials carefully: this manual, nameplate and overall dimensional drawings, thus to get familiar with the product’s total weight and installation methods and prepare corresponding lifting facility and special tools.


2 The transformer should be kept at least 300mm away from walls and other equipment during installation. Transformers installed side by side should have at least 300mm clearance.


3 The minimum safe distance between conductors and ground should conform to IEC76-3-1 POWER TRANSFORMERS-INSULATION LEVELS AND DIELECTRIC TEST-EXTERNAL CLEARANCES IN AIR.


4 The minimum safe distance between the HV coil and ground is listed as follows:


HV voltage£1kV6kV10kV15kV20kV35kV
Net distance (mm)406090120160250

5 Usually, the transformer can be placed directly onto the service site and then be put into operation after installation and inspection. If the transformer must be fastened in place for shock-proof purpose or if there are other special requirements, bolts should be embedded into the foundation. The position of the bolts should be in line with the installation holes of the transformer according to outline drawings. To secure the transformer, remove the wheels and bolt the transformer to the foundation.


6 The connections between live parts must be secure. The torque to be applied is listed as below:
