Three Phase Low Loss Oil Immersed Power Distribution Transformer
Product Overview
Oil immersed transformer produced by SHUANGFENG can be divided into S9，S11, S13 and S20 based on its performance, Oil immersed transformer can widely used in indoor or outdoor of Grid, industrial and mining enterprise, construction project, oil field, IDC , engine room, etc.
● Fully sealed, maintenance-free, high short-circuit resistance, no leakage;
● Low loss, low noise, low temperature rise, safe and reliable operation;
● On-load capacity and voltage regulation power transformers can realize unattended, remote control, remote measurement, and computer control management;
Product Advantages
Key component-iron core
● The company has its own silicon steel sheet cutting line, and the iron core adopts laser-marked high-permeability silicon steel sheet---quality assurance and cost reduction;
● The non-punched iron core design is combined with the international marching type strapping structure to make the electric field distribution in the iron core joints well-distributed---the no-load loss can be reduced by 4-6% by comparing with similar products in the market;
● Special processes ensure iron core can be fixed tightly- NO shift in transportation.
Key component-coil
● Different structures (drum, foil, spiral, continuous) to meet the diverse needs of customers;
● The end angle ring effectively improves the coil characteristics under impulse voltage-----voltage well-distributed;
● There is an oil guide structure inside the coil to greatly reduce the temperature rise-----eliminate the risk of transformer short circuit;
● Separate voltage regulating coil in the larger-capacity products to ensure the ampere-turn distribution in the core is well divided.
Key component-oil tank
● The oil tank adopts barrel type or bell type - more stable structure;
● The heat dissipation element adopts chip radiator-----better heat dissipation;
● The wall of the tank is made directly by bending machine - strengthen tank’s mechanical strength and effectively improve products’ appearance;
● Flat type tank cover-----easy to maintain;
● The edge of tank is sealed with oil-resistant rubber material, and there is sealing strip mark in the tank ----- prevent leakage;
● Strict inspection of fluorescent leak test and pressure test—prevent leakage;
