FRP warning spheres, aircraft marking balls for high voltage lines

Product Description

Product Description
Product DiscriptionAviation obstruction marking sphere is designed to provide daytime visual warning or nighttime visual warning if comes with reflective tape, for electricity transmission line and overhead wire for aircraft pilots, especially cross river high voltage transmission lines. LANYU power line marker ball adopts high-grade Fiberglass Reinforced Plastics (FRP), diameter 600mm,800mm,900mm.Customization acceptable.The color of marking sphere should be aviation orange, white and red. Normally, the marking spheres are placed on the highest line. Where there is more than one line at the highest level, white and red, or white and orange spheres should be displayed alternately. This alternating color scheme provides the most conspicuity against all back ground.OperationVisible Distance1200 metersVoltage Range35KV-1000KVConductor diameter6.5-55mmMechanical structureColorOrange, Red, White, Orange/White, Red/WhiteSphere bodyFRP(Fiberglass Reinforced Polyester)Cable clampAluminum alloyBolts/nuts/washersStainless steel 304Diameter600mm800mmWeight6.9KG/9KGThickness3mmDrain holesYesOptionall Preformed Armor Rodsl Reflective StripWarranty2 Years Applications for warning planesHigh-rise Power transmission LinesHigh slung Cable-car linesRopeway cablesGuy WiresAerial marker balls Functions&Features:• Fiberglass Reinforced Polymer durable material with better weather resistant• Super corrosion resistant character, stainless steel bolts and nuts• Aluminum alloy cable clamp guarantees good corrosion resistance• Various size of cable clamps are available to fit for customers’ cable conductor• Drain holes structure can prevent accumulated rain water inside the spheres• Stacking compatible design, save storage space and freight charge• Optional Preformed Armor Rods provide better protection against vibration and abrasion• Optional Reflective tape is more durable and economical solution for night visibility• Both sphere diameters of 600mm and 800mm are availableInstallation procedure of Power line markers:1) At the mount point on the alerting ball, wrap cable protecting bars round cables for 1000-1200mm long, with two ends of protecting bars extending 200-300mm beyond the surface of the ball, as shown in Figure 1.2) Fix the plastic wires which are mounted on lower hemisphere of the ball onto the cables and twist them, as shown in Figure 2.3) Combine the lower hemisphere with the upper hemisphere according to module codes. Turn the hemisphere during the assembly and make sure two hemispheres are joined into position .4) Insert stainless steel bolts(M12*35) and then put flat washers and spring washers around each bolt. Tighten each nut at last, as shown in Figure 4.Packing&Shipping: Contact Us
