11kv Electric Crossarm Composite Cross Arm Insulator

Product Description    At present, composite polymer tensioninsulators are widely used in power gridtransmission lines, accounting for about 50% of the line silicone rubberinsulator consumption. Among them, the proportion of linear towers is higher. Almost all linear towers in heavily polluted areas use composite insulators.Composite polymericinsulators 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.ModelRatedVotageSpecifiedCantilever LoadStructureHeightCreepage Distance(kV)(kN)(mm)(mm)FS-11/151115200±5350RAW MATERIALS:End FittingsCoreSheds and HousingHot dip galvanized cast iron or cast steelEpoxy & Glass fiber(ECR is available)HTV Silicone RubberMin. thickness of the galvanization: 86μmDiameter(mm): Φ38, Φ40, Φ55, Φ70, Φ90, Φ120Color: Grey, Red  Notes:1.

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. ExhibitionWe 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
