Design FeatureThe composite insulator series consisit of fiberglass epoxy resin lead-out rod, silicon rubber housing and hardware. Through once-molding technology and special, the silicon rubber housing and core rod were tightly integrated, so accidents caused by the interface electrical breakdown are avoided. With special colloid installation and compression Joint Technique in the connection of the fiberglass epoxy reisn lead-out rod and the hardware, the insulator has the advantages of high mechanical strength, nice figure, small volume, less weight. Another advantage is the hardware which plated Zinc to resist erosion, can be interchanged with pocelain insulation.
PerformanceI Excellent Electrical characteristics, high mechanical strength, and the extension intensity of fiberglass epoxy resin lead out rod has 2 times stronger than general steel, 10 times higher than porcelain material. It could be more safe and reliable.
II Good resistance to soiling and flashover, not require clean. The flashover voltage is 1.6-2 times than the same creepage of porcelain insulator. It is very useful in heavy pollution areas.
III Small volume, light weight,(only 1/6-1/19 of the porcelain with the same voltage level) flexible structure, convenient to transportation and installation.
IV The silicon rubber housing has great hydrophobic property, which can protect against inside wet, not require the monitor of preventative and clean, reduce daily maintenance.
V Good sealing performance, strength antielectrical erosion, the tolerance leakage degree reaches TMA 4.5 degree, the products have excellent resistance to erosion, resistance to low temperature and can be applicable for the ambient temperature from -40°C to +50°C
VI Good shock resistance and collision resistance to prevent crash, bend and wrest. It can be interchanged with porcelain and glass insulator.
