Dry-Type Transformer Series

A: Product Overview

SC(B)13 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 SCB11 product, and the load loss s more than 10%lower than that of the SCB10 product The energy-saving effectis excellent, the operation is economical, and maintenance-free.
• Low noise: The noise level of the product is more than 10-15 decibels lower than the current professional standard JB/T10088-20166-220kV 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 miture. The product has 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-proof, anddoes not pollute the environment.
• Insulating materials such as glass fiber winding the col have self-extinguishing characteristics, wil not generate arc due to short circuit.and the resin will not generate toxic and harmful gases under high heat.
• Highmechanical strength: The resin with fller makes the expansion coefficientdifference in the casting body small, the curing shrinkageate is small, the internal stress is small, and the hardness of the cured product is high. In the epoxy resin encapsulation layer of thenner and outer surftaces of the high and low votage coils, there are The prefabricated reinforcing material has a dense structure likeelnforced concrete, so the mechanical strength is greater than that of pure epoxy resin, and it can wthstand the sudden short-circutelectromotive force without damage.

D: Technical Parameters

E: Common Worries & Pain Points of Global Electrical Contractors & Purchasers

When sourcing 10kV epoxy cast dry transformers for urban construction, commercial complexes, underground spaces and industrial plants, buyers always face these core troubles:

• Unclear multi-tap voltage options, cannot adapt to unstable local grid voltage fluctuation;
• Non-standard loss parameters, unable to accurately calculate long-term power consumption and investment payback period;
• Single connection group and fixed impedance, mismatching local grid standards and high-voltage switchgears;
• Incomplete capacity range, unable to cover small workshop to large industrial park power demand at one stop.

F: How Our Standard Parameter Sheet Solves All Procurement Concerns

• Multiple high voltage tap modes for diverse regional power grids The table provides 3 adjustable tap schemes: ±5%, ±2×2.5%, -1/+3×2.5%, matching 10kV / 6.3kV / 6kV high voltage and 0.4kV low voltage. It perfectly adapts to voltage instability in suburbs, factories and remote areas, no extra custom tap modification required.
• Full standardized loss data for precise cost accounting Complete data of no-load current, load loss and no-load loss are listed for 30kVA~2500kVA full range. Buyers can calculate annual power loss cost based on actual running hours, clearly judge energy-saving benefits of SC(B)13 high-efficiency model.
• Dual connection groups & two graded impedance for universal matching Dyn11 and Yyn0 two connection groups are optional, complying with power grid standards of most countries. Two short-circuit impedance grades (4.0% / 6.0%) are classified by capacity, realizing seamless matching with mainstream high voltage switchgears to avoid equipment damage caused by short-circuit surge.
• Full capacity series to cover all engineering scenarios The specification covers small capacity 30kVA for small workshops up to 2500kVA for large industrial zones. One sheet contains all mainstream models, no repeated inquiry for different project load demands.
