Oil-immersed Transformer
1.Low loss, low noise and high reliability.
2.Excellent dynamic thermal stability.
Oil-Immersed Transformer Description:
Oil-Immersed Transformer Special Features:
Low loss, low noise and high reliability.Excellent dynamic thermal stability and high over-load capacity.Simulation analysis was carried out for the core mould design, thus to greatly reduce noise level. Simulated lightning impulse wave process was carried out for HV winding mould design, thus to greatly improve product's anti-lightning impulse capability.Oil-Immersed Transformer LV winding:LV winding is manufactured with high quality foil conductor, so the ampere-turn balance is excellent and the transverse magnetic flux leakage is low. The anti-short circuit capability is thus greatly improved. Oil conduit is rationally designed in the windings to increase winding's heat dispersion surface, effectively reduce temperature and improve transformer's overload capability.
Oil-Immersed Transformer Insulation Structure:
The transformer adopts class-A insulation. The HV and LV windings are arranged in concentric way. Between the windings are oil-clapboard insulation structure built with paper cylinder and small oil conduit.
Oil-Immersed Transformer Tank:
The tank is jointed with high-quality steel. Rust-removing and phosphorization processes are carried out for the tank surface, then the surface is coated with FVC anti- erosion paint, thus to effectively prevent grease pollution and chemical erosion. The appearance is nice and harmonic with the environment. The whole structure is easy for installation and maintenance. It can be widely applied in outdoor environment and under harsh conditions.
Oil-Immersed Transformer Accessories:
The transformer is equipped with HV & LV bushings, oil drain valve, earthing bolt, lifting board, rating plate, pressure relief valve and other accessories. Transformers of over 800kVA power are equipped with signaling thermometer and gas relay.
Main measures for preventing oil leakage:Superior large-width steel plate is selected as material and no vertical joins on the tank wall.
