Composite insulators are also known as organic composite insulators, rubber insulators or non-porcelain insulators. They are composed of organic synthetic materials, mainly rods, gold fittings, umbrella skirt sheaths and bonding layers.
1. The metal fittings are the mechanical load transfer parts of the composite insulator, which are assembled together with the mandrel to form the connecting parts of the insulator.The quality of the structure affects the strength of the mandrel and the mechanical properties of the insulator.
4. One part of the bonding layer is to connect the sheath with the mandrel with adhesive, and the other part is to connect the umbrella skirt with sealing adhesive.The bonding quality is directly related to the level of internal insulation.

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 8, 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. We have a long-standing and close relationship with the China Electric Power Research Institute(CEPRI).
Different types of products are available from our company. We are pleased to receive your inquiry and will reply to you as soon as possible. We stick to the principle of "Quality first, Service first, Continuous improvement and Innovation to meet the customers" for the management and "Zero defect, Zero complaints" as the quality objective. We believe that through our continued efforts and pursuit, we will be able to achieve a win-win situation!
1. All composite insulators are packed in weatherproof containers in order to protect the products during land, air, and sea transportation. Several different grades of packaging can be offered depending on the mode of transport and the expected storage conditions. The packaging options that we offer are
1) standard grade/prefabricated packing,
2) economical grade/cardboard carton, and
3) best grade/closed wooden crate.
Since the user best knows their crate requirements, they should select the option that is most suited to their needs and include that information in the purchasing specification. Special packaging arrangements can be accommodated upon request.
2. Each container is marked with the number of insulators it contains, the catalog number, the manufacturer's name, and any other customer requests.
3. Each packing (wooden Cases or Paper ubes) attached specification and certification of products.
