Silicone polymer housing composite metal oxide surge arresters function as overvoltage protection devices for power transmission and distribution systems. These devices utilize the non-linear volt-ampere characteristics of zinc oxide material. Under standard operating voltage, current passing through the arrester maintains microampere or milliampere levels. When overvoltage occurs, resistance decreases rapidly, discharging excess voltage energy. Unlike traditional arresters, these units operate without discharge gaps, relying on zinc oxide non-linear properties for current discharge and interruption.
HAIVO manufactures two primary housing configurations: silicone polymer housing and porcelain housing metal oxide surge arresters. Both designs support voltage ratings from 0.22-500kV for porcelain versions and 0.22-220kV for composite versions. The silicone polymer variant facilitates straightforward installation and maintenance procedures. Its sealing structure supports consistent operation across various environmental conditions. These devices protect power transmission and distribution systems from overvoltage events, supporting continuous business operations across utility, industrial, and commercial infrastructure projects.

These surge arresters operate within defined environmental parameters. Ambient air temperature ranges from -40℃ to +40℃. Installation altitude should not exceed 2000 meters above sea level. System frequency must remain between 48Hz-62Hz. Power frequency voltage applied across arrester terminals must not exceed the device's continuous operating voltage rating. The units withstand earthquake intensity up to 8 degrees and maximum wind speeds of 35m/s. These parameters support deployment across most industrial applications and commercial infrastructure projects.
The standard model designation follows the YH10W -12 format. Each component conveys specific product information. "YH" indicates silicone polymer housing metal oxide surge arrester. The numeric value following YH specifies nominal discharge current in kA. "W" represents gapless construction. The final numeric value following the hyphen denotes rated voltage in kV. This standardized nomenclature supports efficient commercial procurement processes and accurate product selection for engineering teams.
Silicone polymer housing offers reduced weight and enhanced pollution resistance compared to porcelain versions. Both materials provide appropriate sealing performance for their respective voltage ranges. Silicone polymer variants cover 0.22-220kV ratings, while porcelain versions extend to 500kV.
Select based on system rated voltage, required nominal discharge current (5kA, 10kA, or 20kA), and specific creepage distance requirements. Reference the technical specification tables to match system parameters with corresponding model numbers.
These gapless arresters require minimal routine maintenance. Periodic visual inspection for housing damage and proper connection integrity supports long-term operation. The design facilitates straightforward replacement procedures when necessary.
Silicone polymer housing provides appropriate pollution resistance for coastal and industrial environments. Verify that installation altitude and temperature parameters fall within specified operating conditions for the selected model.
