35KV SCB14 Dry-type Transformer 50-5000KVA

SCB14 series 35kV cast resin dry-type transformer is a mature high-efficiency energy-saving power transformer complying with IEC60076,GB/T1094 and national energy efficiency standards,covering rated capacity 50kVA to 5000kVA.It is widely adopted in indoor power distribution projects such as urban substations,high-rise buildings,shopping malls,chemical plants,new energy projects,underground comprehensive pipe corridors and data centers,ideal for fireproof and pollution-free power supply sites.

Core Product Features

1.Optimized Silicon Steel Core,Low Power Loss

High-grade grain-oriented cold-rolled silicon steel sheet with full miter joint cutting process and rational core stacking design.No-load and load losses are much lower than SCB10/SCB11 models,saving long-term running electricity cost and reaching advanced energy efficiency level.

2.Vacuum Epoxy Cast Copper Windings

High/low voltage coils adopt oxygen-free copper wire,integrally cast with high-purity epoxy resin under full vacuum casting.Compact solid coil structure prevents moisture,dust and chemical erosion,features excellent short-circuit withstand capacity and anti-crack performance.Standard connection group:Dyn11/Yyn0,customizable upon customer grid demands.

3.Safe&Eco-friendly,No Fire Hazard

Oil-free design eliminates oil leakage,explosion and fire risks;epoxy resin is flame retardant and self-extinguishing.Can be directly installed indoors without dedicated fire isolation room,cutting construction cost greatly.

4.Dual Cooling Mode&Strong Overload Capacity

Standard cooling:AN(Natural Air Cooling)

Optional AF(Forced Air Cooling with axial fans):allows about 150%temporary overload for peak load condition

Optimized shock absorption structure ensures low operating noise,applicable for residential and downtown environments.
