10KV S13 Oil Immersed Transformer 50-5000KVA

The S13 series 10kV oil immersed transformer is a high-efficiency energy-saving distribution transformer designed per international and GB national standards,covering rated capacities from 50kVA up to 5000kVA.Widely deployed in urban power grids,industrial parks,mining facilities,commercial complexes,new energy power stations and rural power renovation projects,it serves as core voltage conversion equipment for medium-to-low voltage power transmission and distribution systems.

Core Structural&Technical Features

Low Loss Amorphous Silicon/High-Grade Cold-Rolled Silicon Steel Core

Adopts high-permeability oriented cold-rolled silicon steel sheet with full mitered cutting process,optimizing core lamination layout.Compared with S11-type transformers,no-load loss is reduced by over 20%,effectively cutting long-term grid operation power consumption and meeting national energy efficiency grade 1 requirements.

High-Purity Enameled Copper Winding

Coil wound by high-conductivity oxygen-free copper wire,insulated with high-temperature resistant cellulose paper and advanced vacuum impregnation varnish.Uniform winding structure improves short-circuit withstand capability,restricts temperature rise under full load and prolongs service life.Customizable connection groups:Dyn11,Yyn0 per client’s grid configuration demands.

Sealed Oil Immersed Tank Structure

Corrosion-resistant carbon steel fuel tank with fully welded sealing craft,filled with high-quality mineral insulating transformer oil.The oil acts as insulation and heat dissipation medium;corrugated radiator fins eliminate the need for external cooling fans for most specifications,realizing natural oil circulation heat dissipation.Optional conservator or fully sealed hermetic tank design prevents moisture and air ingress to slow oil aging.

Reliable High&Low Voltage Bushings

Porcelain or composite insulating bushings fitted on high-voltage(10kV)and low-voltage side terminals,excellent outdoor creepage resistance,adapting to humid,dusty and moderate polluted operation environments.On-load/off-circuit tap changer equipped on HV side for±2×2.5%voltage regulation to counter grid voltage fluctuation.
