Dry-Type Transformer Series

A: Product Overview

SC(B)12 epoxy resin cast dry-type transformer can be used as a replacement product for oil-immersed distribution transformers. It is one of the best-performing products among all types of dry-type transformers. It isespecially suitable for urban power grids and high-rise buildings., Business centers, theaters, hospitals, hotels, tunnels,subways, stations, docks, airports, underground power stations, test rooms, combined substations and other importantplaces.

C: Producr Features

• Low loss: The no-load loss of the product is more than 30% lower than that of the SCB10 product, and all losses are lower than theSCB13 dry-type transformer, with excellent energy-saving effect, economic operation, and maintenance-free.
• Low noise: The noise level of the productis more than 10-15 decibels lower than the professional standard JB/T10088-2016 “6-220kV transformer sound level”.
• Low partial discharge: The resin mixture adopts foreign advanced mixing methods and vacuum fim degassing technologies to make themixture evenly stirred and completely eliminate air bubbles in the mixture. The producthas only very low partial discharge, which can becontrolled below 5PC. Both the high and low voltage coils are cast under vacuum and pressure, so that the resin insulation has both fulencapsulation and inter-turn impregnation. The pouring body has a dense solidified structure, flame-retardant, explosion-proor, anddoes not pollute the environment.
• Insulating materials such as glass fiber winding the col have sell-extinguishing characteristics, willnot generate arc due to short circuit.and the resin will not generate toxic and harmful gases under high heat.
• High mechanical strength: The resin with fller makes the expansion coefficient difference in the casting body small, the curingshrinkage rate is small, the internal stress is small, and the hardness of the cured product is high. In the epoxy resin encapsulation layerof the inner and outer surfaces of the high and low voltage coils, there are The pretabricated reinforcing material has a dense structurelike reinforced concrete, so the mechanical strength is greater than that of pure epoxy resin, and it can withstand the sudden short-circuit electromotive force without damage.

D: Technical Parameters

E: Common Concerns of Global Engineering Buyers

When purchasing 10kV indoor dry distribution transformers for urban construction, industrial parks and underground facilities, overseas contractors usually face these core worries:

• High operation loss leads to long-term excessive electricity cost, increasing project total expenditure;
• High noise and partial discharge fail to meet strict standards of hospitals, subways and underground stations;
• Poor flame resistance & explosion-proof performance brings fire risk in closed indoor environments;
• No complete full-capacity parameter data, cannot quickly match the transformer capacity for actual load demand.

F: How SC(B)12 Series Solve Your Procurement Pain Points

• Ultra-low energy loss to cut long-term power cost
  SC(B)12 adopts upgraded low-loss design, no-load loss far lower than SC(B)10 models, maintenance-free operation to reduce daily running expense for factories and commercial projects.
• Low noise & ultra-low partial discharge for sensitive public sites
  Noise value is 10-15dB lower than national standard JB/T10088-2016; partial discharge controlled below 5PC, fully compliant with strict requirements of hospitals, theaters, tunnels and underground power stations.
• Flame-retardant & explosion-proof safe epoxy casting structure
  Vacuum pressure casting process eliminates internal air bubbles; glass fiber insulation material is self-extinguishing, no toxic gas generated under high temperature, zero pollution for indoor enclosed power distribution rooms.
• High mechanical strength resists short-circuit impact
  Reinforced epoxy casting structure withstands sudden short-circuit electrodynamic force without damage, effectively protecting matched KYN28A-12 high voltage switchgear.
• Complete 10kV full-range standardized parameters for fast model selection
  This official parameter sheet covers 30kVA~2500kVA full capacity for 10kV/6kV/6.3kV grid, with dual Dyn11/Yyn0 connection groups and graded 4.0% / 6.0% short-circuit impedance, flexible high voltage tap options to adapt unstable local grid voltage fluctuation.
