Warmly welcome, dear friends!   Wish you shall have a nice time here!

Here is the detailed info for  CHIIB SC(B)10-30~20000KVA/35KV, hope you like it.

CHIIB Epoxy Resin Insulation Three-phase Dry-type Transformer SC(B)10-30~20000/35.


Customer can order the dry type transformer which always include a case ( stainless steel case ). But, he can order the Ontology too. The transformer within 110KVA ~ 10KVA is without fan and temperature controlling, as its lower power and lower speed temperature rising.

First, the specification:


Model implication: SC(B)10-30~20000/35

S -------------------------------- Three-phase

C -------------------------------- Epoxy resin insulation

B -------------------------------- Low voltage case coil

10 ------------------------------- Performance level

30~20000 --------------------- Rated capacity (KVA)

35 ------------------------------- Rated voltage (KV)


The series of epoxy cast dry-type transformers value high-quality materials, formulation science,

advanced manufacturing and testing equipment is made according to strict production process. Products with high reliability and long life characteristics. Depending on the use of the environment, can be configured to 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.


1. Security, fire, pollution-free, can be run directly on the load center.  

2. HTT using German technology, high mechanical strength, resistance to short-circuit capability, partial discharge, thermal stability, high reliability and life of plants. 

3. Low loss, low noise, energy-saving effect, maintenance-free.  

4. Thermal performance, overload capability, forced air cooling can increase the capacity to run.

5. Moisture resistant, and adapt to high humidity and other harsh environments.  

6. Can be equipped with temperature monitoring and improve the protection system.

7. Temperature control system using intelligent signal, automatically monitor and display three-phase winding road of their operating temperature, can automatically start and stop the fan, and has an alarm, trip and other functions set.  

7. Small size, light weight, small footprint, low cost of installation.  

8. High quality cold-rolled silicon steel core, 45-degree miter joints ladder structure, the use of three core cut to the corner two red and five cross-cutting process step ladder and stacked cut sheet iron craft, improved the seams of the flux distribution, reducing the core of the vibrational energy.

9. One core to the surface with insulating resin curing and sealing process, effectively reducing the load loss, load flow and core noise.  

10. High voltage coil insulation class F high-quality wire and advanced insulation materials around the system, with a larger capacity cooling coil along the axial airway.

11. This structure has good resistance to current impact, temperature resistant, anti-cracking and excellent heat dissipation.

12. Multi-level sub-cylindrical structure, strong ability to withstand over-voltage and low partial discharge level.

13. Coil fitted after the casting mold by vacuum drying, the whole process of casting and curing process in accordance with pre-programmed to complete the curve, precise process control to ensure that the coil no holes, holes.  

14. Foil using low-voltage coil structure, effectively low-voltage, high current coil ampere-turns using wire-wound type of imbalance, but there is no axial foil coil winding turns and axial spiral angle, effectively eliminating transformer short-circuit axial force to ensure that the coil current density within the high voltage ring load can be distributed freely along the axial adjustment to reduce the sudden short-circuit when the low radial force.

15. After winding the coil end of the curing resin seal, to avoid the entry of foreign matter and moisture.
