Knowledge on transformer: 

Cast coil transformers have windings (the primary one and the secondary one) that are solidly-cast in resin with the vacuum process. This manufacturing process guarantees the transformer windings covered in a strong epoxy resin with a high dielectric strength. It also protects the device from harsh or severe operating environments with high electrical demands. Cast coil transformers are well-suited for applications that require long service life and little maintenance. They represent a cost-effective alternative to medium-voltage, liquid-filled transformers that may pose environmental concerns and incur increased insurance costs. Specifications, materials of construction, application requirements, and certifications are important parameters to consider when these electrical and electronic components. Cast coil transformers also differ in terms of enclosure type, and provide features such as forced-air cooling.

Product specifications for cast coil transformers include primary voltages, secondary voltages, basic impulse level (BIL), and temperature rise. The primary voltage is applied to the terminals of the primary winding, the part of the transformer that is connected to the energy source. With cast coil transformers, primary-voltage values may range from 600 V to 35 kV.

Packaging & Shipping

1 Busbar Type Single Phase High Frequency Electrical Transformers are packed with wooden packages, and must always stand up according to the direction mark of the packages (except for the 220kV current transformers, they are always packing and transport by lying down).

2 You must remove the wood plates of the top and obverse when you open the package, and then dismantle the 4 pcs M16 bolts which fix in the frame of the package, lift up the voltage transformer vertically and slowly from the package.

3 The clients must check the packages when they receive the voltage transformers, if a package has been broken, they must open the package to check the product together with the forwarder, note down the process and send to the manufacturer.
