HY zinc oxide arrester RTA-1 33-36KV
The zinc oxide arrester is the most advanced over-voltage protector in the world.Due to make the resistor disc of core component mainly adopt zine oxide arrester.Compared with the conventional silicon carbide arrester,this presciption of the product improves greatly the volt-Ampere characterisics of the resistor disc and increased through-current capabil- ity at over-voltage so as to bring a radical changes for the characteristics of the arresters.
Under the circumstance of normal operating voltage,the current through the arrester is just on microampere degree.When suffered from over-voltage,the arrester's excellent nonlinear characteristics will make the current through the arrester increase to several thousand amperse, while the arrester wilI be under the circulating state and release over- voltage energy so as to protecting the power thansmission equipments against the damage caused by the over-voltage.
Application & Characteristics
The zinc oxide arrester applies to protect the electrical equipment in AC power system against the damage resulted from atmospheris over-Voltage and operational over-voltage.
Condition of Use
- The ambient air temperatures is no higher than+40℃,no lower than-40℃.
- The altitude above sea level does not exceed 1000-2000m(the altiplanoarea should be indicated when order).
- AC system frequency 50Hz or 60Hz.
- Industrial frequency voltage brought to bear on arrester for a long time does not exceed arrester's sustained operation voltage.
- Maximum wind speed does not exceed 35m/s.
- The earthquake intensity does not exceed 7 degrees.
- The filthy area should be given clear indication.
Technical performance
The technical performance of the prodect is in conformit to GB 110322000,IEC60099-4&IEEE.C62.11 standard technic requirements.
