General
ECR Rods produced by our company has applied the pultrusion process technology, of which high-quality raw materials of reinforcedglass fibers and epoxy resin are used.
Our ECR Rods are designed and manufactured mainly for compositeinsulator use with a variety of cross section diameters ranging from6mm to 110mm at options of anylength.
Applications
Mainly for power and electrical industries, such as composite/polymerinsulators, insulation rod, lightning arrestor, dry power transformerspower resistors, tap changers, switchgears, Cryogenic insulation.underwater conditions, electrical equipment and so on..
Besides, our pultruded ECR rod could also be used in other variousindustries where resistance to stress, weathering and corrosive atmospheres are important.
Properties
ECR Rod has better dielectric strength, stress-corrosion resistance; high surface resistance; higher mechanical strength and stiffnesscompared with E-glass (FRP Rod), wider application ranges than FRPRod(E-glass). Better corrosive resistance; Light weight and long lifecycle; Non-magnetic; Flame resistant; Arc and track resistant: Electromagnetic transparency; Excellent electrical insulation; Non-conductive thermally and electrically.
