Fzsw Series 230kv Composite Line Post Insulator

Product Description In order to improve the mechanical strength of insulator, dielectric strength and resistance to pollution flashover performance, improve production efficiency and reduce cost, to overcome the inherent shortcomings, ceramic and glass insulators to adapt to the development of electric power system, all countries in the world working with organic polymer materials as the base material of composite insulator, used instead of the traditional ceramic and glass insulators.Since the end of the 19th century appeared high voltage transmission lines, pottery and porcelain insulator used for the field of high voltage insulation outside has 100 years of history, with the increase of voltage grade, insulator machine of point load, as well as atmospheric pollution, pottery and porcelain insulator performance exposed in the reuse of the defects. And the use of composite insulator makes up the defect of the pottery and porcelain insulator and weaknesses.  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.   Payment & Shipping Terms:Model Number:FZSW-230/8Minimum Order Quantity:100 pcsPrice:NegotiablePackaging Details:plywood case, fumigated solid wood caseDelivery Time:45~50 days EX-worksStandard:IEC 61952, ANSI C29.1RAW 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, RedNotes:1.

It has good hydrophobicity, hydrophobicity migration and soil resistance, as well as excellent electrical insulation properties and aging resistance, which could prevent effectively those accidents of pollution flashover so as to ensure the safe running of high voltage transmission lines. The modified ECR fiberglass reinforced epoxy resin rod is used as it has good resistance to high temperature, stess corrosion & acid attack, as well as fine damping action, high tensile strength (> 1200Mpa) and resistance to creep and fatigue failure, which effectively ensure the internal insulation quality and mechanical stength of insulators.End fittings are crimped onto fiberglass rod with voice-operated displacement type crimper. The insulators with this crimping technique have high mechanical strength and small dispersion. Taking the most advanced automatic overall injection moulding technic and connection method of crimping for production and assembling, and the whole crimping procedure controlled by computer and the crimping result monitored by ultrasonic detector to assure each product is qualified.  ItemRequirementMeasured ValuedVisual examinationFuchsine,grey or white, no obvious mechanical admixture. Vulcanized sillion rubber with dense and smooth cutting surface.OkHardness (shore A)≮5065~70Tensile strength  (Map)≮44~6Failure elongation  (%)≮150≮180Tearing strength (kN/m)≮10 (right angle sample)12~15Volume resistivity (Ω.m)1X10123~8X1012Puncture strength (kV/mm)Alternating current ≮22≮30Tracking and erosionTMA4.5,erosion depth≯2.5mmTMA4.5, erosion depth
