Composite Long rod suspension insulator is use epoxy rod and rubber sheds external insulation polymer composite insulators. Compare with traditional ceramic and glass insulators, it is more lighter(only about 1/4 to 1/8 of traditional insulator), higher strength(10 times higher than high-strength porcelain insulator), less clearing(anti-water). And it also overcome the short life problem of conventional polymer materials, the life will be several decades. It is the new product in power system.
