FEG-12/5 lightning pillar insulator type I. Introduction FEG-12/5 piercing arc-proof insulator is a new modular structure of the product. Domestic and foreign distribution lines now widely applied the insulated wire, insulated wire inherent resistance but the level of mine, when struck by lightning, accident prone to breakage. At home and abroad to prevent the main measures 10KV overhead insulated wire lightning break taken include: erection of overhead grounding wire; zinc oxide surge arresters installed; installation of metal hoop ring on post insulators. However, the existing technology has the following disadvantages: a larger investment costs, construction and installation of complex, to be stripped insulation layers, resulting in core water and corrosion. This product is a combo piercing arc-proof insulator new modular structure, the composite insulator has good insulating properties and anti-contamination level, applicable to 10KV overhead power lines and supporting insulated conductors, but also prevent 10KV overhead insulated wire lightning protection disconnected. The product also has a wire in order to prevent movement due to thermal expansion and contraction movement barbed teeth structure and piercing clamps for easy installation and construction, reliable, without ripping the insulating layer, can avoid wire core water and corrosion. But also greatly reduce the labor intensity of the operators. Since the post insulators and anti arc clip into one, more so concise and reduce the cost of the line. The products are reliable, less investment, the effect is great for the power sector to prevent 10KV overhead insulated wire lightning break provides a cost-effective way. Second, the structural characteristics 1. This product is a new type of anti-arc insulator modular structure, which is mainly composed of an insulating cover, compression nut, compact seat, move clamps, metal caps, composite insulators, arc rods, bushings and lower metal legs, etc., see diagram. 2. arc rod and the metal cap fitted integrally connected, when lightning strikes, arc discharge between the rod and the lower metal legs, so freewheeling frequency arc burning stick is moved to the arc to protect the insulation from the wire damage. 3. Move the clamps and clamp assembly seat way through dovetail into one, so that the wire is moved due to the thermal expansion and contraction and other reasons, the mobile clamps moves, thereby avoiding the wire is scratched clip. The composite insulators than the insulating performance PS-15 and other electrical porcelain insulators good, and creepage distance, improves the level of anti-contamination insulator can meet the majority of users of the anti-contamination insulators requirements. 5. Insulation cover organic composite material with good insulation properties, aging resistance and flame retardant properties, to its assembly on the outside of the metal cap, can play the role of insulation protection. 6. This product has the piercing spines teeth structure, easy installation and construction, without stripping the insulator wire insulation, avoid core water and corrosion, it can greatly reduce the labor intensity of workers. 7. keep birds on overhead wires causing a short circuit hazards unique structure. 8. can tolerate about five times frequency large current arc burning. Technical standard product standards for GB11032-2000 (eqvIE60099-4.1991) "metal oxide surge arresters without gaps for AC", JB / 8952-20045 "ac systems complex, coat gapless metal compounds arrester" FEG-12/5 using the conditions 1, ambient temperature: -40 ℃ ~ 50 ℃ 2, altitude does not exceed: 1500m above sea level, the maximum wind speed: 35m / s4, earthquake intensity: 8 main advantage FEG-12/5 lightning pillar insulator type: lightning effect has nothing to do with the ground arrester thanks "and the potential" deal with technology, it's lightning grounding effect with the device independent of whether there is, thus eliminating the need to install a conventional arrester must be grounded trouble. So simple to install and easy to use. □ Product electrical parameters table
