Detailed Description

3KV Compact Polymer Housing Lightning Surge Arrester for Power Transformers / Distributors Protection 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 materialincluding 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 thecurrent-transmit ability of resistance slice, as a result, the capability of arrester has been improved basicallyand thoroughly. Features: 1. Compact and Lightweight 2. Extremely Safe Pressure Relief Performance 3. Superior Performance against Environmental Contamination 4. Directly Molded Structure 5. Compliance with International Standards(IEC60099-4) 6. Simple Support Structure 7. Manufactured at Advanced ISO-9001 certified facilities Applications: 1. Distribution networks 2.
