Dry-Type Transformer Series

A: Product Overview

SC(B)-NX2 dry type transformer is our economical grade 2 epoxy cast transformer for global industrial power distribution. It is especially suitable for urban power grids, high-rise buildings, business centers, theaters,hospitals, hotels, tunnels, and subways., Stations, wharts, alirports, underground power stations, test rooms, combinedsubstations and other important places.

B: Model meaning

Core Buyer Highlights
1.Custom capacity (30~2500kVA) & voltage (6/6.3/10kV) to fit your project grid
2.Optional foil low voltage winding for heavy load, better heat dissipation
3.Grade 2 efficiency balances purchase cost & daily power loss
4.Oil-free epoxy cast design, low maintenance for indoor projects

C: Producr Features

• Low loss: The no-load loss of the product is more than 30% lower than that of the SCB10 product, and allosses 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 “6-220kVtransformer 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 product has only very low partial discharge, which can becontrolled below 5PC. Both the high and lowvoltage 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 solidfied structure, flame-retardant, explosion-proo, and does not pollute the environment.
• Insulating materials such as glass fiber winding the col have sel-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 sma, the curingshrinkage rate is smal, 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 prefabricated reinforcing material has a dense structurelike reinforced concrete, so the mechanical strength is greater than that of pure epoxy resin, and it can wthstand the sudden short-circuit electromotive force without damage.

E: Optimized Key Advantages for Global B-side Buyers

1. Dual connection group Dyn11 & Yyn0 optional

Solve pain point: Different industrial loads & local grid standards require customized wiring design. Dyn11 eliminates harmonic interference for precision equipment; Yyn0 fits regular residential & commercial power supply, one model covers all your project wiring demands.

2. Multiple high-voltage tap shift ranges

Solve pain point: Unstable regional grid voltage often causes equipment overheating or failure. Adjustable taps maintain stable output voltage to adapt fluctuating power supply in remote factories, suburban parks and overseas mining sites.

3. Graded 4% / 6% short-circuit impedance design

Solve pain point: Improper impedance will burn downstream switchgear during short-circuit faults. 4% impedance for small units saves power loss; 6% for large capacity limits surge current, lowering your extra replacement & maintenance cost of supporting cabinets.

4. Low no-load current & Grade 2 standard loss performance

Solve pain point: Idle standby loss accumulates huge monthly electricity bills for factories with shift production. Low idle current cuts constant power waste, balanced Grade 2 loss reduces your long-term operation expenditure without overspending on high-end Grade 1 models.

5. Full capacity range from 30kVA to 2500kVA

Solve pain point: Multiple project phases need transformers of different sizes. Complete single-series capacity covers small retail buildings, medium workshops and large industrial parks, simplifying your unified procurement and after-sales management.
