First, [FS-66/5] composite crossarm insulators organizational structure: composite suspension insulator is connected to gold insulated mandrel, silicon rods and plastic umbrella cover both ends with three parts. Epoxy glass fiber insulation mandrel The withdrawal of short, it is the skeleton of composite insulators, plays a supporting umbrella cover, internal insulation, coupling fittings at both ends, and withstand the mechanical loads multiple roles, with high tensile strength, generally up to 600Mpa above, is 2 times that of ordinary steel, 5 to 8 times the ceramic material, and has good dielectric properties and chemical resistance, as well as good resistance to bending fatigue, creep and impact sex. Silicone rubber mainly plays a protective umbrella sleeve mandrel, blocking rain and snow, increasing the creepage distances and the role of insulation products, silicone rubber is the polymer matrix, combined with a flame retardant, anti-aging agents, coupling high temperature and pressure curing agents filler made with good hydrophobicity and migration, as well as good corrosion resistance, aging resistance, electrical insulation properties. And it has a high flashover voltage and resistance, chipping performance, uniform voltage distribution, compared with porcelain under the same conditions which flashover voltage is porcelain more than 2 times. Second, [FS-66/5] composite crossarm insulators Conditions of Use Ambient temperature: not higher than + 40 ℃, not lower than -40 ℃; Altitude: not exceed 1000m; (1000m above can be GB311.1-1997 Correction) Power Frequency: less than 100Hz; mechanical load: no more than the rating of each product. Third, [FS-66/5] Composite crossarm insulators on the line of the basic requirements: 1. The wire size among the scope of application. 2. The white wire sag relative error does not exceed 100mm 3, the installation process usually requires workers to climb the ladder hanging on the wire, requiring wires and suspension points should meet the strength requirements. 4, when the wire hanging ladder, as well as for multi-multi-loop below have spanned should meet safety regulations (line section) 5, abnormal promptly. Fourth, Company: Shanghai Yi Electric Co., a new type of your business, factory construction area of ??over 10,000 square meters, is set high and low voltage plant equipment, indoor and outdoor vacuum circuit breakers, box-type substation (European and American), cable distribution boxes R & D insulators, surge arresters high pressure automatic reactive compensation devices and other projects, production, operating in one of the national key high-tech enterprises.
