Scale:
It covers an area of 220,000 square meters, owns a fixed assets of over 100 millionYuan(RMB),and employs 1200 engineers, technicians and workers in total.It is the largest company engaging in research, design, and making of electric power fitting and electric power transmission line constructing fitting.Also it is a key enterprise supplying the necessary accessories for electric power transmission and distribution projects all over China.
Technology:
Over 300 of engineers and technicians serving here. Inspecting and Measuring Center of line fitting of the state electric power corporation, together with design and research institute of line fitting, are put in the manufacturer. Once it was entrusted by Ministry of power–Energy Resources to draft and administer Chinese standards of electric power fittings. It has successfully supplied 110KV,220KV,330KV,500KV and 220KV,500KV compact type transmission and distribution projects firstly in China. Moreover, the electric power and constructing machines used in the first 630,720 big section power transmission lines in China is also designed and supplied, as well as the in used line fittings of 500KV transformer substation serving for 250(diameter)tubular bus-bar. All the nonstandard fittings used in the stretching-across electric lines across Yangtze River, Huanghe River, Zhujiang River, Heilongjiang River were developed and supplied by the manufacturer too.
Equipment and quality:
The manufacturer is equipped with nearly 1000 sets of chief equipment, such as processing center, numerical controlled machine tools, die-casting machines, moulded-material extruders, etc. And it has various laboratories individually for electrical,mechanical,chemical,physical, precision measuring and aging tests, which are equipped with many advanced inspecting and test instruments,such as an ARL metal analytical instrument,a 100-ton horizontal pulling test machine, a 300kgf electromagnetic vibrating table,etc. The equipment and powerfultechnical ability listed above, together with perfect quality system and advanced technological ability assured good quality of our product, which enjoy high reputation at home and abroad and have won the prizes of national silver medal and the title of good quality product of the water resources&electric power ministry and Jiangsu province for many times.
Influence:
The leading products of the manufacturer are electric power fittings and medium and mini-sized tools for AC. & DC transmission lines and distribution substations with the voltages up to 500KV. The fittings consist of 9 series. The manufacturer can design and manufacture nonstandard product for specific projects. It has a fitting production capability of more than 15,000 tons per year. Also it develops over 200 kinds of product every year. It is equipped with over 100 kinds of medium and mini sized tools, which produce 13,000 sets of tools per year. Its product with trademark NING are not only used in all important transmission & distribution projects of China, but also exported to more than 40 countries and areas in Europe, Asia and Africa. Especially the several series of fittings developed in recent years such as fittings to damper oscillations, Enclosed fittings, high elevation fittings, high strength fittings, fittings for insulated lines, improved damper spacers for multi—split conductors,250(diameter) tubular bus-bar fittings new type spacer-dampers for six-bundle conductor are leading in China and some of them have been mass produced and popularly used .
Future:
All the staff and workers will stick to the management policy of “Consumer first, Product quality excellent, Prestige highest, Service best” as ever to satisfy consumers both at home and abroad with our excellent product, reasonable price, and good prestige. And contribute to the electric powerconstruction at home and abroad as we can.
