Product Description

Product Advantage:
3. Excellent resistance to electric corrosion: the surface leakage and flashover of the insulator form an irreversible mark caused by deterioration. The general standard is level 4.5, while the composite insulator is level 6-7.
Wuhan Line Power Transmission Equipment Co., Ltd. Was established in 2008 and is mainly engaged in the research, development, production and sales of high voltage transmission power composite insulator series products.
Located in Wuhan, we implement ISO 9001: 2015 Quality Control, ISO14001: 2015 Environmental Management System, and ISO 45001: 2018 Occupational Health and Safety Management System. The company has more than 400 acres of land and has built six assembly line production workshops with a total of 80, 000 square meter of workshop space.
The company's products are AC composite long-rod insulators with rated voltages from 10kV to 1000kV and rated mechanical loads from 70kN to 550kN; DC composite long-rod insulators of rated voltages from ± 400kV to ± 1100kV and rated mechanical loads from 160kN to 1000kN; Composite line post insulators up to 550kV, substation post insulators, braced post insulators, pin insulators, cross-arm insulators, and composite insulators for electrified railways. All products are certified to international quality standards - IEC, ANSI, AS, BS, CAS, GB, and more.
In addition, we provide our clients with solutions for complete power equipment and its accessories, such as porcelain insulators, glass insulators, HDPE insulators, power fittings, cables, surge arresters, fuse cutouts, etc. We have a strong core technical team and a complete R&D system, and guarantee our clients secure operational solutions and sustainable business models.
We have already exported our insulators, accessories, fuse cutouts, etc. To North America (Canada, USA, Trinidad and Tobago, etc. ), South America (Ecuador, Venezuela, Peru, Argentina, Brazil, etc. ), Europe (Bulgaria, Norway, Sweden, Czech, Poland, etc. ), Australia, New Zealand and so on. We are one of the main suppliers to State Grid of China(SGCC). Up to now, our company has won the bidding for more than 10 lines of AC and DC UHV transmission projects of the State Grid, with more than 30, 000PCS ± 800kV and 1000kV composite insulators in operation.
