We started to export 10kV Transmission Line Steel Pole to Philippines from 2004 and supply more than 50,000 pcs each year.
Our firm introduced whole set of good-sized numerical control hydraulic
folding equipment(1280/16000) as well as equipped with a series of
good-sized professional equipments of armor plate-flatted machine,
lengthways cut machine, numerical control cut machine, auto-closed up
machine, auto-arc-weld machine, hydraulic redressing straight machine,
etc. The firm produces all sorts of conical, pyramidal, cylindrical
steel poles with production range of dia 50mm-2250mm, thickness
1mm-25mm, once taking shape 16000mm long, and large-scale steel
components. The firm also is equipped with a multicolor-spayed
pipelining. At the meantime, for better service to the clients, our firm
founded a branch com. The Yixing Jinlei Lighting Installation Com,
which offers clients a succession of service from design to manufacture
and fixing.

Participating in the acceptance of the State Grid DC Construction Department, the State Grid East China Power Control Center, the State Grid Jiangsu Power Control Center, China Academy of Electric Power, Zhejiang Electric Power Design Institute, State Grid Jiangsu Power Maintenance Branch and other units. Experts of the acceptance team reviewed and accepted the overall plan of the Huai'an auxiliary control station device, and conducted comprehensive tests on specific functions. They all agreed that the software logic and hardware functions of the Huai'an Assistant Control Substation of the East China Power Grid frequency emergency coordination control system meet the design requirements. Qualified by experience, agreed to the factory.
The main function of the East China Power Grid Frequency Emergency Coordinated Control System is to monitor the real-time running status of each DC, all pumping units and a large number of controllable loads. When the DC fault is blocked or the power is suddenly dropped, the power grid has a large power shortage and multiple DCs are generated. Power emergency boost, pumping and pump cutting, rapid cutting of control measures to interrupt the load, etc., as far as possible to avoid the low-level load reduction action of the third line of defense, reduce social impact.
The Huai'an converter station co-control device is part of the East China Power Grid's frequency emergency coordination control system and uses the SCS-500E series stability control platform from Guodian NARI. The device monitors the operation of 4 converters. When a DC fault occurs (including DC blocking and emergency downhill), the DC power loss is calculated, and the DC power loss is sent to the DC coordinated control master station. Simultaneously, the local DC power boosting function and the remote command are realized at the same time. Ground frequency confirmation function.
Guodian NARI SCS-500E type stability control device successively demonstrated Xiangjiaba-Shanghai ±800kV UHVDC power transmission demonstration project, ±800kV Jinsu DC transmission end power grid security and stability control system project, Three Gorges power station delivery project, and Jiangsu and Henan It has been widely used in security and stability control projects in Hubei, Anhui, Gansu, Qinghai, Shandong, and Liaoning, covering more than 30 provinces and cities across the country, and has played an important role in the safe and stable operation of power grid systems.
