electrified railway type lightning arrestor

Metallic oxide surge arrester with 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 metal oxidesurge arresteris encapsulateted with the process of one-off compression moulding forming,this typelightning arrestorhas the follow excellent characteristic: 1. Excellent outer insulating performance (high flashover voltage), anti-electro erosion, aging resistance, heat-resistant, compact size, light weight, as well as outstanding anti-explosion, soiling-resistant performances. 2. It also features excellent protective performance, superior composite insulating material moldability, and can easily achieve reliable sealing with no moisture intrusion,due to the distinctive invention patents and production procedures. 3. Thistypesurge arresterdemonstrates a strong performance in resisting falling, bending, tension, shocking, and impact. 4.Electrified railway typesurge aresteris of high flow rate, compact size, and light weight, and adopts temperature control interruption protection technology to realize short response time, low residual voltage, and small leaking current. type ratedvoltageoflightningarresternominalvoltageof system continuous operating voltage of lightning arrest referenceVoltageat 1mAD.C.≥residual voltage leakagecurrent at0.75U1mA≤specificcreepagedistance≥lightningimpactcurrent8/20µs5(10,20)kAsteep wave impactcurrent1/10µs5(10,20)kAoperatingimpactcurrent30/60µs0.25(0.5,1)kAkV effective value r.m.skVkVcrest value crest≤µAmm/kVHY5WTT-42/1204227.53465120138983036 HY5WTT-84/2408455681302402761963036 HY10WTT-42/1204227.53465110127903043 HY10WTT-84/2208455681302202531803044
