S11-35KV Oil-Immersed Electrical Power Transformer

Gnee Steel (Tianjin) Co., Ltd. is one of the most professional s11-35kv oil-immersed electrical power transformer manufacturers and suppliers in China. Welcome to wholesale customized s11-35kv oil-immersed electrical power transformer at competitive price from our factory. Good service and quality products are available.

GNEE Steel oil immersed power transformer

S11-M series fully sealed oil immersed power transformer developed and produced by GNEE has the advantages of low loss, low noise and high efficiency, which can achieve good energy-saving effect and reduce pollution. Compared with the ordinary oil immersed transformer, the fully sealed transformer cancels the oil conservator, and the change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated oil tank. The transformer is isolated from the air, so as to prevent and slow down the deterioration of oil and insulation aging, enhance the operation reliability, and avoid maintenance in normal operation.

S11 type 35 kv series main performance parameters of the products

oil immersed distribution transformer

1.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.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.

2.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.

3.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;

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.
