High Efficency Dry Type Transformer Made With Epoxy Resin 2500
Dry Type Transformer Advantages:
Cast resin dry type transformer, eco-friendly, high efficiency.
- Low loss, low noise, low partial discharge, high reliability. Best
for general users , such as hospital, tower, hotel, etc.
- Strong capability with anti-short circuit, high anti-lightning
- 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.
- 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

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:
|Net distance (mm)||40||60||90||120||160||250|
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
6 The connections between live parts must be secure. The torque to
be applied is listed as below:
