Nanjing Electric International Co., Ltd.-Product

Since the year of 1958, the total sales quantity of “LD”brand toughened glass insulator achieved to a record over 100 millions pieces, it was 50% of the total domestic capacity and one sixth in the worldwide . In the past 60 years, Nanjing Electric has supplied the “LD” glass insulators to many National Key Project such as:”Sanxia Dam project” ，“West-to-East Power Transmission Project”，“Anhui electricity power to east”，“Xinjiang Electricity Power Transmission Project”,”Shanxi Electricity Power Transmission Project” and “North-South Electricity Power Transmission Project”, also made great efforts to the “One belt , One road” and the global electricity development .Since the first EHV project of “Jing-Su”EHV transmission line was awarded to Nanjing Electric ,there were 24 EHV transmission projects were awarded to Nanjing Electric ,including 10 EHV AC line and 14 EHV DC lines. The total quantity of “LD”insulators from of Nanjing Electric supplied to EHV project achieved 4.46 Millions pieces.

Composite Insulator

Nanjing Electric has advanced production equipment of various types of composite insulators at home and abroad to ensure product quality to meet customer requirements.The number of kneading machines,Open Mill machines,rubber extruder is over 20 sets. The capacity of rubber compounding is about 6000 tons and with more than 20 sets injection machines including 1100KN,550KN, 500KN, 330KN. The capacity of long rod composite insulator is over 1.3 million pieces(Convert into 110KV insulators),We have over 10 sets imported pressure welding equipment with 175/165/140 size and can completely meets the market requirements of all kings if composite insulators.

The company mainly produces high-voltage suspension porcelain insulators, high-voltage line Post porcelain insulators, high-voltage line pin porcelain insulators, high-voltage porcelain cross-arm insulators and porcelain insulators for electrical appliances.In order to accelerate the development of the industry and continuously improve the product brand, the company continues to invest 25 million yuan, the expansion of the test hall and product technology center, and constantly introduce advanced technology and equipment, with reliable product quality, to provide high quality services for domestic and foreign customers.

Hollow Composite insulator

Hollow composite insulators are mainly used as key components for increasing creepage distance between high-voltage bushings such as transformer bushing, GIS bushing and wall bushing. Main features: Explosion proof, No explode and damage the surrounding equipment; Light product weight; Good seismic performance, Suitable for earthquake prone areas; High electrical performance and insulation level; Excellent UV resistance; Environmentally friendly materials, harmless to health and safety.

Intelligent Electric Equipment

The main products include prefabricated substations, vehicle-mounted mobile substations and protection and control products.

High voltage bushing is an important equipment element in power system, which takes on the function of current carrying and insulation when the high voltage line passes through the wall and equipment shell, and the connection between equipment or the grounding of equipment. Since 1958, the company took the lead in the trial production of capacity bushings in China, and after more than 50 years of production and manufacturing experience, it has produced more than 100,000 high-pressure bushings for the power transmission and transformation industry, accounting for about 50% of the total number of domestic online operation at present. On the basis of the original casing production technology, our company actively explores new materials and new technology of casing products, and in 2001, we successfully developed FRP reinforced dry capacitor core, and developed FRP reinforced dry casing series products by using this technology. At present, the company has oil paper capacity type, adhesive paper capacity type, glass fiber capacity type of three kinds of technology of high-pressure bushing production line.
