35 KV grade epoxy transformer
Detailed Description
The voltage is 35 KV, the capacity of the distribution transformer SC (H) B 10 is 100 -3150 KVA, and that of the power transformer SC (H) 10 is 800-25000 KVA. The new generation H Grade insulation transformer is developed on the basis of the advanced technology; both of the design and the production process are fully in accordance with the standard of IEC60076, GB6450 and GB/T10228. And therefore this type of transformer is widely used in the places such as electric plants, power plants, industrial and mining enterprises, and the power distribution stations and other distribution systems.
Features of products:
1. Low loss: this type of transformer is fully in accordance with the standard of the nation and the requirements of the energy-saving.
2. the partial discharge is lower than 10Pc
3. The insulation level is H-grade, and the bearing temperature is 180℃, the temperature fluctuant of the operation is low and high overload ability. It can runs for a long time under the circumstance of 120% overload of the cooling system, and even 150% overload of the force cooling system.
4. Low noise, the noise is 20dB lower than the national standard.
5. Reliable, safety, easy-maintenance, high mechanical property and high ability of withstanding short-circuit.
1. The transformer applies the H-class new insulation materials. It uses the mixed insulation system of the C-class insulation NOMEX material and the H-class insulation resin, and therefore the products has the features of high ability of withstanding overload and the thermal shock.
2. the high and low voltage coil applies the new H-class epoxy, and it uses the static mixing for the mixture, and casts under the 1-2 mbar vacuum circumstance and therefore the products has low partial discharge.
3. The high voltage conduct applies the H-class enameled wire insulation, with a vertical cylinder airway sub-structure, and it adopts a unique round system to reduce the intergovernmental and inter-voltage level and therefore improve the impact-resistant level.
4. The transformer adopts a new structure to lower the noise. The core uses the pull board, and the widening band structure. The material is the high-quality magnetic silicon conduct, and it uses the five lap step process and therefore greatly reduces the noise and the no-load current of the products, the running noise id 20dB lower than the national standard, and has reached the first level of the national citizens’ requirements.
