Product Description
At present, composite polymer tension insulators are widely used in power gridtransmission lines, accounting for about 50% of the line silicone rubber insulator consumption. Among them, the proportion of linear towers is higher. Almost all linear towers in heavily polluted areas use composite insulators. Composite polymeric insulators have solved the pollution flashover problem that has plagued the power grid for many years with their excellent anti-flashover performance.
This series of products are composed of three parts: glass fiber epoxy resin drawing rod, silicone rubber umbrella skirt and metal fittings. The silicone rubber umbrella skirt adopts the whole injection and compression process, thus solving the key problem affecting the reliability of composite insulators -- the interface electrical breakdown.
The connection between the glass drawing rod and the metal fittings adopts the unique glue fitting technology, and adopts the most advanced pressing technology in China. It is equipped with the automatic sound wave flaw detection system with high strength, beautiful appearance, small volume and light weight. The metal fittings are galvanized to prevent corrosion and can be used interchangeable with ceramic insulators.

Company Profile
Our company with strong strength, reasonable price, good service and a number of enterprises to establish a long-term partnership.With high quality products and perfect after-sales service, we have won the consistent reputation of customers all over the country.We sincerely welcome customers from home and abroad to visit, investigate and discuss business cooperation.
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.
Our company specializes in the production of composite insulators for transmission lines. The main structure is composed of rubber, epoxy glass fiber core and metal end fittings.
Compared with similar ceramic and glass insulators, silicone rubber insulators have the following advantages:
(1) Small size, light weight (1/7~1/10 times that of ceramic insulators with the same voltage), good elasticity of the shed, not easy to break, convenient transportation and installation, and economical.
(2) High mechanical strength. FRP rods have high tensile strength, which is 5-10 times that of ceramic materials. The cross-section of the core material is small, the product is small in size, light in weight, and high in tensile strength. It is easy to manufacture large-tonnage insulators above 300KN.
(3) High antifouling performance and good aging resistance. The silicone rubber injection molded shed has good hydrophobicity and mobility, which makes the insulator have high anti-pollution flashover voltage and good electrical corrosion resistance.
(4) Easy installation and maintenance, which can greatly reduce maintenance costs caused by power outages and manual labor intensity.
(5) The production process is simple and the delivery time is short.
Exhibition
We have been participating in various exhibitions at home and abroad from 2010 to 2019. At the exhibition, relevant people from the industry and us saw our products directly and closely.
Inspection Before Shipment
Before dispatched, the goods will be performed routine test and sample test comply with related standards. In case damage during the transportation, each one's sheds and housing will be checked thoroughly. Superficial defects of an area greater than 25 mm² (the total defective area not to exceed 0.2% of the total insulator surface) or of depth greater than 1mm.
Packaging & Shipping
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.
