Using cutting-edge technology imported from overseas, we created the SC10, SCB10 series, and SC11, SCB11 series padding thin-insulation dry-type distributing transformers. Because the winding of these transformers is sealed with epoxy, the resin insulating dry-type transformer is explosion-proof, flame-retardant, low maintenance, and compact, allowing it to reach deep into the load center.

With the advanced technology brought in from averseas,we developed SC10,SCB10 series and SC11,SCB11 series padding thin-insulation dry-type distributing transformer whose winding is sealed up with epoxy,therefore the resin insulating dry-type transformer is flame-retardant,explosion-proof,free from maintenance and pollution,and it is compacted and can go deep into load center.

A new generation of low noise and low loss transformers has been developed recently, and it is the reel core fully sealed power distribution transformer. The product is further strengthened by its iron core, which has no joints and significantly lowers no-load loss and no-load current by 60% to 80%. The high and low coils are continually wound on the core column, and the winding is tight and concentricity is good. performance against stealing. More than ten decibels were lost in the noise level. The rise in temperature is only 16–20K. The no-load loss is decreased by 20% to 30% and the orientation loss of silicon steel sheet is fully exploited due to the continuous winding of the iron core (pure circular cross section).

The reel core fully sealed power distribution transformer is a new generation of low noise and low loss transformer developed in recent years. Its iron core has no joint, greatly reduces the no-load loss and no-load current, reduces the no-load current by 60%~80%, the high and low coils are continuously coiled on the core column, the winding is tight, the concentricity is good, and the product is enhanced more. Anti-theft performance. The noise decreased by more than 10 decibels. The temperature rise is low 16-20K. Because of the continuous winding of iron core (cross section is pure circle), the orientation loss of silicon steel sheet is fully utilized, and the no-load loss is reduced by 20%~30%.

The casting coil of SCB10 Dry Type Power Transformer is filled with short glass filaments and adopts a segmented circular structure and axial air channel in the coil to improve heat dissipation conditions.
