Binder, the band is wound on the resistor disc, and electrode, the insulating supporting are drawn in the case where the terminal of the band is provided with
Post by the electricity compressing tablet with it is described under draw electrode and combined.
Preferably, also include fixed seat, the tower seat in the fixed seat connection electric line.
Preferably, the fixed seat is zinc-plated fixed seat.
Preferably, the resistor disc is metal oxide resistance.
Preferably, the electricity compressing tablet is ring or the tablet with geometry.
The series gap metal oxide arrester that the utility model is provided, its advantage is：Using line type oxygen
Compound arrester, when thunderbolt is to steel tower, because the flashover voltage of the residual voltage ratio insulator of arrester is low, jumps when can reduce thunderbolt
Lock, the probability having a power failure；Noted by electric glue between compressing tablet and resistor disc and be integrally bonded structure, when thunderbolt destruction is met with not
Can fragment splashing；By installing insulation supporting pillar additional, suspension insulator can be replaced in electric line, save transmission ＆ distribution electric installation
Through costly.
