13.8KV Oil Immersed Distribution Transformer
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;
