Our high voltage surge
arrester are very reliable high quality
protection devices used in outdoor overhead
applications to protect HV networks, distribution
transformers, motors and cables against
both atmospheric and switching overvoltages.
The
gapless design incorporates highly non-linear
metal oxide (ZnO) varistors elements which
are designed and manufactured completely
in-house.
Relevant standards: ANSI/ IEEE C62.11-1993, IEC 60099-5 |
