Over Voltage Metal Oxide Gapless Lightning Arrester Ceramic For Electric Railway Systems
1, Lighting Arrestor Description
The lighting arrestor is the most advanced over-voltage protector. It is widely used as protective
devices against switching and lightning over voltages in power electrical systems such as power
transformers ,distributors,generators, compensation capacitors. Its core component--resistance slice adopts the material including zinc oxide and many kinds of metal oxides, compared with traditional silicon-carbide arrester,its volt-ampere characteristic of resistance slice has been improved to great degree, as well as the
current-transmit ability of resistance slice, as a result, the capability of arrester has been improved basically
and thoroughly.
2, The metal-oxide surge arresters without gaps for electric railway, which is used to protect
all kinds of electrical equipments, contact network, electric locomotive from the damage of
atmosphere overvoltage and operating voltage.
