Polymer surge arrester Y5W-10/27Q

AC

The total insulated polymer-housed metal-oxide surge arrester, which our company research and develop,is a new-type overvoltage protection device. The voltage range is 3～35kV,and for the main technical parameters,it’s same with the conventional arrester with same voltage level.3～35kV polymer-housed metal-oxide surge arrester, which the type is displayed after with additional characteristic code “Q”,such as YH5WZ-51/134Q, the type of total insulated polymer-housed metal-oxide surge arrester without gaps used for the 35kV system power station. The total insulated polymer-housed metal-oxide surge arrester,which is in parallel with the circuit,can protect AC system with relevant voltage class from the damages by lightning overvoltage and operating overvoltage.According to the different objects of protection,the arrester will be devided into several types as follows, power station (Z),power distribution (S),parallel compensation capacitor (R), electirc machinery (D) and so on. Ambient conditions of operation 1. Ambient temperature : -40℃～+40℃. 2. Altitude : no exceeding 2,000m. 3. Power frequency : 48Hz～62Hz. 4. Earthquake intensity : no exceeding 8. 5. Max. wind speed : no exceeding 35m/s. 6. The power frequency voltage, which imposed among terminals of arrester for a long term,should don’t exceed the continuous operationg voltage of arrester. For the total insulated polymer-housed metal-oxide surge arrester,it’s integral forming with insulated lead at high voltage terminal and core of the arrester.And there’re advantages that simple outline and structure, good sealing performance, high dielectric strength.
