EI Transformer for Parking Management System

Parking Management system transformer is also named as Jacking system transformer. It is an AC voltage converting device. Usually use it to conver the network voltage into genearl output voltage. For example, 400V in to 220V out, 380V in to 220Vout, 220V in to 110V out. The transformes should be low instantaneous start current, no static current sound, no vibration and sufficient instantaneous power.

Product Feature:
1. The tranformer has wiring terminal, it is very easy to install.
2. Low loss and low noise.
3. It is made with high permeability silicon steel and high quality copper wire.
    And it can be made with temperature proector to ensure the safe operation of the transformer.
4. Can design accorinding to customer's working environment and working space.

 EI  Transformer Process

• EI lamination has 0.35mm and 0.5mm thickness, material has Z11/H12/H14/H18/H50 of option.
• The insulation for coil has 0.075/0.125mm thickness polyster film. 0.18/0.25mm DMD insulation paper and T410 Nomex paper. The brand of polyster film is DUPONT. The layers of overlap is deponds on the safety agent requirements.
• Primary and Secondary winding wire is polyesterimid enameled, have 130/155/180/200degree for option.
• Primary lead wire from type UL1617 double insulation for 600V voltage and 105 degree or UL3321 XLPE for 600V and 150degree.
• Secondary lead wire from type UL1015 for 600V voltage and 105 degree.
• Outer insulation is overlap 1 layer 0.075/0.125mm thickness polyester film or 0.18/0.25mm DMD insulation paper or T410 Nomex paper.
