Metal Oxide Polymeric Lightning Arresters

Product Description

Application: Polymer Housed MOA Type YH5W-(9-36)KV /YH10W-(9-36)KV is applied to protect 9-36KV electrical transport equipment from damage by atm osphere over-voltage and operation over-voltage. The outdoor normal application conditions are as following:
(1) Ambient temperature: -40'C ~ 45'C;
(2) Sea level high should be no more than 2000m;
(3) Power frequency should be between 48Hz and 62Hz;
(4) Maximum flow speed should be no exceed 35m/s;
(5) Max pull force of conductor on the top of MOA is 147N;
(6) Earthquake level shall be no exceed than 7 degree;
(7) Frequency power voltage long-term pulled on MOA shall not exceed than continuously operation voltage of MOA.

Type and technical parameters:
(1) Specification of MOA shall meet with IEC60099-4 and ANSI Standard;
(2) Technical parameters of MOA (see the table)
