Production Description


Wortai Electric is a chinese leading manufacturer & Supplier of Polymer Surge Arresters for Distribution with with over 20 years experience,  the voltage rating from 3kV to 36kV, the nominal Discharge Current is available for both 10kA and 5kA, OEM and ODM services are welcome.

M.V. Surge Arresters are used to protect transformers and other equipments in station and distribution systems against the damage by atmospheric (especially lightning effects) and operational conditions.Metal oxides surge arresters without gaps are designed to prevent probable damages in the case of typical surges in energy systems while it has no negative effect on energy systems in normal operation voltage. This special feature of gapless arresters originating from non-linear characteristics of metal-oxide varistors between voltage and current scales. The non-linear feature is much higher compared to SiC surge arresters.

YH*W type surge arresters are normally equipped with an arrester disconnector connected in series: In case of failure of the arrester due to discharges above rated values, it disconnects the failed arrester from the system, thereby preventing its being a continuous source of fault, besides, enabling the site people to easily find the failed arrester.
The continuous operating voltages Uc  (as per IEC) and MCOV (as per ANSI) differ only due to deviations in type test procedures.
For Specification or application beyond the range listed here,please contact us for detail.
Above parameters are also applicable to the porcelain housed Surge arresters.
