36kv Line Post Polymer Insulator Horizontal Clamp for Power Transmission

Product Description Insulators are essential to the safe and stable distribution of electricity generated at power plants. The station post insulators found in power handling equipment at power plants and substations support electric cables and other equipment, isolating them from the ground.The station post insulators support each piece of equipment; several can be connected to form an insulator column.Rated Voltage(kV)Height(mm)Dry Arcing Distance(mm)Creepage Distance(mm)Specified Cantilever Load(SCL)Max.

All section lengths are based on vertical & base or bolt end fittings.2. Below 220kV electrical data shown for composite line post insulators without corona rings and mounted vertically. Wuhan Line Power recommends corona rings to be installed at 220kV and above.3. Additional section lengths and creepage distances are available. Contact sales agency for details.4. All dimensions, tolerances and tests are within allowable IEC standards or ANSI standards.5. All dimensions are in millimeters(mm). If in inches and pounds, please specify.6. We can design according to the end user's requirements.  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
