On July 7, 2021, SAICMOTOR base photovoltaic power generation project undertaken by Shanghai Huaming Power Equipment Engineering Co., Ltd. (hereinafter referred to as 'Huaming'), a subsidiary of Huaming Equipment Group, officially started. Leaders from the local government and representatives of SAICMOTOR Fujian Branch attended the groundbreaking ceremony. The SAICMOTOR Base Distributed Photovoltaic Power Generation Project is located in Ningde city. It uses 32 color steel tile plants with a total installed capacity of 21MW, of which about 10MW is connected to the 10kV high-voltage system, divided into two access points; About 11MW is connected to a 380V low-voltage system, with 33 access points in total. After completion, the annual average power generation capacity is about ...

Pakistan, an emerging market full of opportunities. She is the second largest economy in South Asia, the sixth most populous country in the world, an important country along the 'Belt and Road', and an important economic and trade partner of China. In the power industry, her potential cannot be underestimated: NTDC, Pakistan's National Transmission and Distribution Company, predicted that from 2020 to 2047 Pakistan's average electricity demand would grow by 4.8%, and that by 2047 total electricity consumption was expected to be five times that of 2018. However, currently total installed capacity of Pakistan is relatively low and can hardly meet the local industries’ and residential electricity demand. Therefore, the electricity market is poised to grow. Since its first...

Alcoa Corporation, who conducts operation in more than 10 countries, is the world’s 8th largest producer of aluminum. Since 1888, approximately 75% of its aluminum is still in use today. As the founder of the modern aluminum industry, Alcoa’s innovative technologies have helped the aerospace, automotive, packaging, construction, commercial transportation, consumer electronics and industrial markets achieve multiple development milestones. The time goes back to the early autumn of 2018. Huaming received the inquiry of tap-changers for Alcoa Norway rectifier transformers. The transformer capacity was 26.1MVA, 33kV, and has 96 steps, which has very special requirements for tap-changers. In view of this, Huaming conducted several technical communication with the customer and finally deter...

In the past 3 decades, around 60% of global power market demand came from industrial, commercial and utilities, which highlights the close connection between economic activities and power consumption. At the beginning of 2021, the foreign epidemic situation gradually stabilized, and the global power market is picking up, ushering in new opportunities for Huaming's overseas market. With years of unremitting efforts, Huaming has been recognized by more and more customers, who trust us and are willing to use our products. Therefore, in the first quarter of this year, the direct export of Huaming tap-changers rose sharply compared with the same period last year, which was a good start for 2021. Throughout the first quarter, Huaming’s direct export orders increased by 119%, turnover in...

This ZWC de-energized tap-changer is suitable for oil-immersed power transformers and special transformers, such as furnace or rectifier transformer with a rated frequency of 50 or 60 Hz, a maximum equipment voltage of 145kV and maximum rated current of 1000A. Tap changing takes place when the transformer is de-energized, so as to change the transformer ratio and stabilize the output voltage.ZWC tap-changerDrive mechanismZWC is of a split structure and consists of two parts: the body and the drive mechanism. The transformer manufacturer is responsible for connecting these two. It is of linear type and equipped with two insulating support plates as a frame. It is used in power transformers and large-scale distribution transformers. It is installed in the space between the windings and the t...
