Product Decrbition

The series of epoxy resin casting dry-type transformers high-quality materials, scientific formula, advanced production and testing equipment is made according to strict production process. Products with high reliability,long life characteristics. Depending on the use environment can be configured with different levels of protection or do not configure the shell casing.For high-rise buildings, commercial centers, airports, tunnels, chemical plants, nuclear power plants, ships and other important places or special environment.

 

Product Design:

1) Using a proprietary dry-type transformers PD control process for casting internal stress control technology, the cast-type transformers insulated internal control in the ideal state, ensuring key performance dry-type transformers;

2) in the design process to field a strong product analysis and calculation,by adjusting the parameters field so that all components are the starting field in the insulating material 75% or less, to ensure the performance of advanced technology products;

3) Related links will introduce in advance of relevant performance parameters

the design of the product design so that the product design input requirements are included to make the output better in line with requirements.

 

Features:

1) security, fire,pollution, can be run directly on the load center;

2) by the German high HTT technology, mechanical strength, resistance to

short-circuit capability, partial discharge,thermal stability, high reliability, long life;

3) low loss, low noise,energy-saving effect, maintenance-free;

4) good heat dissipation, high load capacity, can increase the capacity run time forced air cionogd; moisture resistance, adapt to high humidity and other harsh environment operation;

6) equipped temperature detection and protection systems. Intelligent signal temperature control system can automatically detect and display the three-phase winding their tour operating temperature, can automatically start and stop the fan, and alarm,trip settings and other functions;

7) small size, light weight, small space and low costs of installation .

 

Structural features:

1) The core is made of high quality cold-rolled silicon steel sheet, 45 degree miter security joints disintegration structure, using three cut two punch core to cut corners and five cross-cutting process step ladder iron clip and stack technology, improving the seams magnetic flux distribution, reducing the vibration energy core. Core integrally curing and surface of the insulating resin sealing process, effectively reducing the load loss, no-load current and core noise;

2) high-voltage coil using high-quality Class F insulated copper wire with the international advanced insulation material around the system, larger capacity with cooling coil in the axial airway. This structure has good resistance to current impact resistance to temperature changes, resistance to cracking and excellent thermal performance. Using multistage cylindrical structure, strong ability to withstand over-voltage and low partial discharge level. After circling Die vacuum drying casting, casting and curing the entire process is completed in accordance with programmed technology curve, sophisticated process control to ensure the coil nonporous, hole;

3) low-voltage coil using the foil structure, effectively solve the low voltage, high current coil is wound types of ampere-turns imbalance, but there is no axial foil coil winding turns and the axial helix angle, effectively eliminating transformer short circuit axial force to ensure that the current density within the coils can be distributed freely adjust the axial load voltage coil, reducing the radial force low pressure bursts are short circuit.Coil end winding resin-sealed after curing, to avoid a variety of foreign matter and moisture from entering.
