Protective fittings are mainly used to reduce the vibration amplitude of overhead power line wires and lightning conductors, as well as the equalizing shielding of lines above 330KV and substation insulator strings, such as anti-vibration hammers, spacers, equalizing shielding rings, etc. When the anti-vibration hammer, the spacer bar and the wire clip are connected to the wire, the wire should be wrapped with aluminum tape according to the usage. The MRJ type double split flexible busbar spacer is suitable for keeping the distance between the flexible busbar and its down conductor unchanged and the two wires do not collide. a. Good grip and firm fixed line. b, Energy-saving design, line loss is small. c, Good insulation, no damage to the wire. d. Easy installation and simple maintenance. e, Compact structure, beautiful appearance
