1)Core rod and fittings: | composite long rod insulator consists of a unidirectional reinforced fiber glass core and assembly with two metal end fitting and most of end fittings were forge steel. | ||||||
2)Silicone rubber: | in order to prevent electrical degradation and the electrical leakage currents, the surface of fiber glass core is protected by a layer of high temperature vulcanized silicone rubber and the thickness must be more than 3mm. | ||||||
3)How to connect the fitting with core rod | we use crimp machine to crimped the end fittings onto the ends of core rod. |
