With more than 60 years of experience in the R&D and production of transformer products, Taizhou Haitian Electric Manufacture Co., Ltd. is Oil-immersed On-load Tap-changing Distribution Transformer Suppliers in China. Currently, it has a registered capital of 60 million yuan, covering an area of 96 mu (about 62,000 square meters) with a building area of 26,000 square meters. It owns more than 100 sets of production and testing equipment, with an annual comprehensive production capacity of over 6 million kVA. It can stably undertake the production of 35kV and below transformers, prefabricated substations, high and low voltage switchgears, and various related test projects.
Relying on more than 60 years of industry accumulation, we provide you with stable, efficient and compliant electrical equipment supply guarantee, eliminating worries about insufficient production capacity and delayed delivery. The annual production capacity of 6 million kVA can meet the demand of large-volume orders; the mature production process can realize standardized and large-scale production, greatly reducing the unit product cost and enabling you to obtain cost-effective products.
The oil-immersed on-load tap-changing distribution transformer adopts a high-quality laminated silicon steel core and oxygen-free copper windings with a stable structure and strong short-circuit resistance. Different from conventional oil-immersed distribution transformers, the oil-immersed on-load tap-changing distribution transformer is equipped with on-load tap changers. The transformer realises voltage regulation under load without a power cut, which can adapt to grid voltage fluctuations in real time and maintain high output voltage precision. The oil-immersed on-load tap-changing distribution transformer adopts a fully sealed corrugated oil tank and an oil-immersed self-cooling system. The transformer features excellent insulation performance, stable operation without oil leakage and convenient maintenance. The oil-immersed on-load tap-changing distribution transformer is widely applied to urban and rural power stations, industrial mines and park power supply with large grid voltage fluctuation and complex power load. The equipment achieves higher power supply quality, stronger power supply reliability and long service life.
