10KV SCB14 Dry-type Transformer 50-5000KVA

1.Product Overview

SCB14 series 10kV vacuum cast dry-type transformer is National Class 2 high-efficiency product complying with IEC60076-11,GB1094&latest GB20052-2020/2024 energy efficiency regulation.Rated capacity ranges from 50kVA to 5000kVA;standard primary voltage 10kV,secondary 0.4kV with customizable transformation ratio.

Full oil-free epoxy encapsulated design features flame retardant,explosion-proof and zero pollution,optimized on the basis of SCB13 with further reduced no-load&load loss.Widely used in municipal power grid,commercial buildings,industrial plants,underground subway,photovoltaic power station,chemical and mining projects,the most cost-effective choice for medium-energy-saving power distribution projects.

2.Structure Design

Core Assembly

Adopts high-grade grain-oriented cold-rolled silicon steel sheet with multi-step miter-laminated cutting technique,optimized magnetic circuit to cut no-load loss by 10%~15%vs SCB13.Core surface coated with anti-rust insulated paint,vibration damping structure effectively lowers running noise below industry standard.

HV&LV Windings

10kV High Voltage Coil:High-purity oxygen-free copper wire wrapped with high-temperature resistant insulation,integral vacuum epoxy casting,partial discharge controlled below≤5pC,outstanding moisture-proof&anti-aging property.

Low Voltage Coil:Small capacity:copper wire winding;large capacity:full copper foil winding,uniform current distribution,low extra eddy loss and strong short-circuit withstand capacity.

Epoxy resin is F1 self-extinguishing grade,no molten drop under open fire;standard F-class insulation(155℃),optional H-class(180℃)for high-temperature harsh environment.

Auxiliary Accessories

Built-in PT100 platinum thermal sensors matched with intelligent temperature controller,realizing automatic cooling fan startup,over-temperature alarm and overheat trip protection.Two cooling options:AN natural air cooling(standard),AF forced air cooling;under AF mode,the transformer supports 20%temporary overload operation.Optional IP20/IP23 metal protective cabinet for anti-touch and dust prevention.

3.Core Advantages

Cost-effective Class 2 Energy Saving:No-load loss down 10%~15%,load loss down 8%~12%compared with SCB13,much lower energy consumption than SCB10/SCB11;balances energy-saving performance and procurement cost,ideal for medium-load projects with high cost-performance demand.

Excellent Safety&Eco-friendly:Oil-free construction eliminates leakage,fire and explosion risks;no waste oil discharge,pollution-free,can be directly installed indoors without special fireproof oil pit.

Strong Environmental Adaptability:Stable operation under high humidity,dust,coastal salt fog and mild corrosive atmosphere;applicable altitude≤1000m,ambient temperature-25℃~+40℃,C1 climate grade per IEC.

Low Noise&Minimal Maintenance:Optimized assembling&damping design,running noise 10~15dB lower than standard JB/T10088 requirement;oil-free design removes regular oil replacement and filtration work,only annual simple dust cleaning needed to cut O&M cost.

High Mechanical Stability:Integral cast winding improves mechanical strength against short-circuit impulse,long service life over 30 years under rated working condition.
