Product Overview
The 630 kVA epoxy resin transformer is an energy saving dry type transformer. The coils are encapsulated in epoxy resin, which has the advantages of being flame retardant, fireproof, explosion proof, maintenance free, pollution free, and small in size. At the same time, the scientific and reasonable design and casting process ensure that the partial discharge of the product is far below the international standard.
630 kVA epoxy resin transformer has strong heat dissipation capabilities and is equipped with an intelligent temperature control system with functions such as fault alarm, over temperature alarm and tripping. It also has the function of centralized monitoring and control by connecting to a computer via RS485 serial interface.transformer 630 kvaIt also features centralized monitoring and control capabilities via an RS485 serial interface for connection to a computer. The 630 kVA epoxy resin transformer possesses these advantages, making it widely used in power transmission and transformation systems, such as airports, high rise buildings, commercial centers, residential communities, and industrial plants.
Product Characteristics
|
Characteristics |
Product Technology Advantages |
|
Low local power emission |
Using epoxy resin vacuum casting process, the partial discharge quantity is ≤5pC, which is far below the standard requirement and significantly extends the insulation life. |
|
Anti short circuit ability strength |
The coil is cast as a rigid block, which can withstand the huge electrodynamic force generated during a sudden short circuit, without the risk of displacement or cracking. |
|
Tide resistant |
It can be stored and operated in high humidity environments without pre drying; when used with a protective shell, it is suitable for dusty or corrosive environments. |
