66kv Silicon High Voltage Polymer Disc Composite Suspension Electrical Insulator

Product DescriptionThe composite insulator consists of a mandrel, an umbrella sheath and a connecting harness.The material of the mandrel is glass fiber reinforced plastic, which is used to provide the mechanical properties of the insulator. The sheath is connected to the surface of the mandrel through adhesives to protect the mandrel. The connecting fittings are located at both ends of the composite insulator to connect the composite insulator to the pole tower fittings.      ModelRated Votage Specified Mechanical LoadStructure Height   Minimum Dry Arc DistanceMinimum Creepage Distance Lightning Impulse Withstand Voltage Wet Power Frequency Withstand Voltage  (KV)(KN)(mm)(mm)(mm)≥(kV)≥ (kV) FXBW-66/706670940±157502170410185Payment & Shipping Terms:Minimum 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.

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.  FEATURES: The silicone rubber housing of Composite Line Post Insulator were taken shape by whole injection. 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
