Overview:

HY5WS-12.7/50L zinc oxide surge arresters with metal-oxide surge arresters in addition to the over-voltage protection function

but also in the event of abnormal failure freauency short-circuit current from the device that moves the around automaticall

disengage, withdraw from the grid of zinc oxide surge arresters operationrepair and maintenance convenienteasy to find fault

→Arrester with disconnector works Description:

When zinc oxide arrester failure,mainly increasing the current flowing through the valveso vaive group showed a fever state

due to valve group and negative temperature coefficientthe equivalent resistance caused by heat down.and to promote heat

intensifies.the formation of a vicious cycleThis arrester workina state to pass directly throuah the form of temperature from the

device,when the temperature reaches the value from design to low melting point alloy melting,from the device moves out of the

arrester and ground wire.cut out the defective arrester operationand aive a clear sianal patrol officers for the realization of oxide

lightning"state maintenance"provides practical technical measures

Installation and precautions:

Arrester insulated by a bracket or clamp fixed to the cross armthe upper bolt connected hiah-volfane wire the lower nart of the 

ground must be soft copper wire and grounding wire connections;not allow the use of hard-wire connection with the arrester ground

to avoid lightning damage from the device can not be successfully divorced from
