insulated column off-type lightning arrester

HY5XST series composite insulated from the out-type metal oxidesurge arresterinsulator column be used for AC power system in various dirty area overhead power lines run in insulation and bare wires ,It can limit lightning over-voltage,improve the lightning-resistant level of the lines,reduce the lightning strike trip-out rate so as enhance reliability to power supply of distribution system . We are professionalsurge arrester manufacturer, our Metallic oxidelightning arrestorwith composite wrap is designed according to IEC60099-4 and GB11032-2000 relevant standards, and with piled-up metallic oxide nonlinear resistors as core, this composite insulating oxidesurge arrester is encapsulateted with the process of one-off compression moulding forming 1. This typelightning arrestor adopt patent production process,so that products with high bending performance.other porcelain insulators load is 1.4,2.0,3.0,3.5,4.0KN.Our lightning arrestor can achieve the maximum bending load of 4.0 KN over tolerance. 2. Silicone rubber materials used as external insulation of this typelightning arrestor,external insulation has excellent performance,design big climb from the pollution prevention,can be used in any dirty areas and highland areas. 3. Improve the lightning-resistant level of the line,reducing the rate of lightning trip.line being struck by lightning,the insulator conduction,discharge lightning current of energy into the earth. 4. This typesurge arresteris easy to install,in the past for solved the lightning trip-out problem has takend a number of ways,but never got the desired effect.if use of common surge arrester for protection line,it is very hard to install ,but this product just need to replace the original insulators . 5. Small size and light weight:The design of the disconnector can quickly and conveniently to find the work status of this product it is easy for secure inspection. type ratedvoltageoflightningarresternominalvoltageof system continuous operating voltage of lightning arrestor referenceVoltageat 1mAD.C.≥residual voltage leakagecurrent at0.75U1mA≤specificcreepagedistance≥bending loadlightningimpactcurrent8/20µs5kAsteep wave impactcurrent1/10µs5kAoperatingimpactcurrent30/60µs0.25kAkV effective value r.m.skVkVcrest value crest≤µAmm/kVkNHY5XST-10/33TL1068193337.928.130404HY5XST-17/56TL171013.6295664.347.730404
