HY5WS-17/50TLB zinc oxide arrester with disconnectorDetails:

Electric Co., Ltd. Yueqing Dengrui factory direct【HY5WS-17/50TLB zinc oxide arrester with disconnector】,And provide a variety of【HY5WS-17/50TLB zinc oxide arrester with disconnector】Images, parameters, description and other detailed product information,Dengrui【HY5WS-17/50TLB zinc oxide arrester with disconnector】High quality, excellent price, special requirements can be customized consultation.


HY5WS-17/50L zinc oxide surge arresters for the protection of the system rated voltage 10KV power transformers, switchgear, box-type substation, power cable outlet head, the oil column from the atmosphere switching and distribution equipment such as over-voltage damage.

HY5WS-17/50L 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 frequency short-circuit current from the device that moves the ground automatically disengage, withdraw from the grid of zinc oxide surge arresters operation, repair and maintenance convenient, easy to find fault.

Arrester with disconnector works Description:
    When zinc oxide arrester failure, mainly increasing the current flowing through the valve, so valve group showed a fever state, due to valve group and negative temperature coefficient, the equivalent resistance caused by heat down, and to promote heat intensifies, the formation of a vicious cycle. This arrester working state to pass directly through 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 operation, and give a clear signal 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 arm, the upper bolt connected high-voltage wire, the lower part 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.
 
Dengrui electrical arrester main products are:
Zinc oxide arrester, composite metal oxide surge arresters, drop-arrester, removable surge arresters, surge arresters can be cast type, line type arrester, combined arrester, arrester station type, motor type arrester, distribution type arrester, capacitor-type arrester, electric Railway type arrester, lightning arrester type neutral point, low-voltage surge arresters, surge arrester type motor neutral point of transformer-type arrester, arrester room, discharge counter, surge arrester line monitors, lightning arrester disconnector, etc.; arrester accessories: JS-8; JSY -10; JCQ-C; TLB-type hot blast from the device; arrester mounting bracket (surge arrester mounting plate), conductor (conductive wire from the device), silicone rubber insulated jacket [For more information, please visit: http://www.cndrele.com/ ]
