Lightning Composite line post insulators FEG-12/5, Lightning needle puncture FEG-12 / 5C, FPW-12/5, FPL-12/5 FEG-12/5-type lightning pillar insulator (puncture / non-puncture type) Lightning Composite post insulators FEG-12/5 This product is suitable for AC power system rated voltage 10kV, this product supports wire to prevent lightning strikes disconnection uses for wire range 50-240 (mm2), the instantaneous large current arc trial for 12.5KA, this product does not require a separate grounding lightning Composite post insulators FEG-12/5 model specifications and performance parameters: Model Specifications Rated voltage (kV) insulated wire cross-section mm2 full-wave lightning impulse withstand voltage (peak) kV 1min power frequency withstand voltage (rms) kV power frequency arc current (rms) kA rated withstand bending load KN minimum nominal creepage distance mm Remarks wet FEG-12 / 5A 6-12 50/240 75 42 30 12.5 5360 - piercing FEG-12 / 5C 50/240 75 42 30 12.5 5 360 non-piercing lightning pillar composite insulator FEG-12/5 Features: 1. The product sub-piercing and non piercing (stripping insulation ) two kinds, which is mainly composed of an insulating cover, cramping aluminum fittings, composite insulators, arc rod and lower steel legs and other components, structure, see diagram 1. 2. arc rod and clamp fittings assembled integrally connected, when lightning occurs, causing the arc between the rod and the lower steel legs flashover discharge, a short-circuit channel, successive frequency arc move to arc steel rods and feet between the combustion to protect the wire from burns. Because arc stick bypass sheds and adjusted to the optimum discharge gap, discharge and prevent burn better insulator sheds. 3.FEG-12/5 type having a piercing thorn tooth structure, teeth thorn removable, skinning or not skinned optional use. Thorn tooth using higher strength and better electrical performance than the aluminum-copper alloy surface after electrical (infiltration) plating to prevent oxidation of copper and aluminum in combination, such as copper or aluminum wiring can be used. Piercing need not be stripped wire insulation, core water and avoid corrosion, extremely easy to install construction, can greatly reduce the labor intensity of workers. 4. The use of composite materials than the insulating properties of the insulator PS-15 and other electrical porcelain insulators good, and the creepage distance, improves the level of anti-contamination insulator, can meet the majority of users of the anti-contamination insulators requirements. 5. Insulation cover with silicone rubber material, has good insulation properties, aging resistance and flame retardant properties. 6. been taken into account to prevent the birds on overhead wires causing a short circuit hazards unique structure. 7. can tolerate about five times frequency large current arc burning. Lightning Composite post insulators FEG-12/5 installation: 1. lightning pillar insulator sandwiched trunking should be aligned parallel to the direction of wire mounted on the cross arm, tighten the nut steel foot equivalent conventional insulator installation methods, the arc rods towards the cross arm (cross arm farthest distance) far lateral; arc rods in one direction, preferably toward the load side; 2. piercing cramping way: Set torque wrench according to wire section and weather temperature torque value: 26-32Nm, alternately with a torque wrench, tighten the two symmetrical pressure nut. Check with the naked eye, you can see the basic stab tooth root, then tighten the nut prepared to prevent pressure nut loose. 3. Non piercing cramping way: Strip the insulated conductors embedded in a period of about 65-80mm on insulator clamp fittings with a wrench to tighten the compression nut to drive compacts seat pressed wire; insulation shields fitted in clip Fitting the external line.
