S13 oil immersed transformer

Overview:

The three-phase oil-immersed distribution transformer produced by our company adopts a new insulation structure to improve the short-circuit resistance; the iron core is made of high-quality cold-rolled silicon steel sheets; the high-voltage windings are made of high-quality oxygen-free copper wire and adopt a multi-layer cylindrical structure; all fasteners are specially treated to prevent loosening.

SH15 Amorphous Alloy Transformer

Product Overview:

This product is an oil-filled sealed type. The principle is the same as that of a sealed power transformer. The basic elements of amorphous alloys are iron, nickel, cobalt, silicon, boron, carbon, etc. It is an isotropic soft magnetic material with low magnetization power and no structural defects that hinder the movement of domain walls. It is extremely thin, only 0.027mm, and the filling factor is correspondingly small, only 0.75~0.8. The resistivity is very high, 3~6 times that of silicon steel sheets, and the hardness is 5 times that of silicon steel sheets. Amorphous alloy materials are particularly sensitive to stress.

SH15-M-30~2500/6~10 series products, the no-load loss is reduced by 70% based on the GB/T6541 standard value. Implementation standard GB/T25446-2010 "Technical parameters of oil-immersed amorphous alloy iron core distribution transformers.

35kV power transformer

Product Overview:

The 35kV series power transformers are relatively advanced in design, with significant improvements and enhancements in materials, structure and technology. The high and low voltage clamps are tightened with steel straps or upper beams and side beams to form a solid frame structure, enhance the core clamping force and withstand transportation impact. It has strong short-circuit resistance, beautiful appearance, reliable operation, low loss and low noise, reaching the advanced level of similar foreign products.

The SZ13-20000/35 transformer prototype produced by our company passed the sudden short-circuit test conducted by the National Transformer Testing Center at one time. The high and low voltage coils are equipped with longitudinal oil channels, which are conducive to heat dissipation and can greatly reduce the copper-oil temperature difference and the hottest temperature rise inside the coil.

SG(B)12、SC(B)12 type mains transformer

Product Overview:

Since dry-type transformers have the advantages of strong short-circuit resistance, low maintenance workload, high operating efficiency, small size, and low noise, they are often used in places with high requirements for fireproof and explosion-proof performance. Safe, fireproof, pollution-free, can be directly operated in high-load electricity consumption;

Adopting domestic advanced technology, high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability, and long service life;Low loss, low noise, obvious energy saving effect, maintenance-free;Good heat dissipation performance, strong overload capacity, and can be operated in short-term over-capacity under forced air cooling;It has certain moisture-proof performance and can operate in harsh environments with high humidity;Dry-type transformers can be equipped with a complete temperature detection and protection system. The intelligent signal temperature control system can automatically detect and display the working temperature of each three-phase winding, automatically start and stop the fan, and has alarm, trip and other function settings;Small size, light weight, small footprint, low installation cost.
