Insuiation Polymer Housing Without Interruption Metal Oxide Surge Arrester
Product Description
Type: Power Source Arrester Installation: Parallel Arrester Size: Meidum Shape: Spiral Certification: ISO9001 Features: Reduced Line Maintenance,Good Sealing,Explosion-Pr Origin: Jiangyin Yunfeng, China Structure: Zinc Oxide Arrester Application: AC/DC System Operation Voltage: High Voltage Material: ZnO Function: Protect Electrical Devices in a.C.Power System Trademark: YF InsuIation Polymer Housing Without Interruption MOA
Due to whole-forming for wire of high voltage Terminal and core of MOA,the fully Insulated Polymer Housed MOA has the features of simpie structure,excellent sedl,high dielectricity and longer creepage distance.It can reduce Insulation distance between MOAs,thus suitable for any installation conditions especially for limited spaces in switchgear box and high altitude,heavy pollution areas.
Main parameters of full insulation polymer housed MOA
Metal Oxide Surge Arrester(MOA) without Gaps for A.C.Sytems
Product Overview
MOA is composed of metal oxide varistors,housing(porcelain or silicon rubber),base,upper cover,grading ring etc.Our products have excellent performance in accordance with IEC international standard IEC600 99-4(2000) and China National Standard GB11032-2000 for "Alternating Current Gapless MOA".Polymeric housed MOA manufactured by AMTECH features small size,lightweight,simple manufacturing process,good sealing,explosion-proof,long working life,wounded-proof,high pollution resistance and reduced line maintenance,etc.
MOA Classification Code
Gapless arrester electrical parameter
Note:Please drop "H" if it is porcelain arrester.
Main principie
Zinc-oxide lightning arrester is the most advanced Over-Voltage Protector at present in the world. The voltage current characteristic of the varistor has been changed compared with traditional carborundum arresters due to the multiple metal oxide materials application in the core element-varistor,which has greatly improved the varistor's throughput capacity and brought thorough change to arresters'characteristics.
When arrester is under normal voltage,there is only microamp current through it .When it is under high voltage,arresters'excellent nonlinear voltage current feature gets into play,so the current through arresters will reach thousands of amperes and the arresters are at conducting status,releasing over-voltage energv to effectively protect the power transmission equipments from damage caused by over voltage.
Application and features
Zinc-oxide lightning arrester is protective equipment for electrical devices in A.C.power system from damage caused by over voltage or over-voltage operation.
