Orient Power composite suspension insulator is particularly suitable for using in large span, compact lines with high mechanical tensile load in polluted areas.

220kV composite suspension insulator used Conditions:
1. Ambient air temperatures within the range of -40 degree Celsius to +40 degree Celsius;
2. Altitude above sea level not exceeding 1, 000m; If the 220kV composite suspension insulator altitude is higher than 1, 000, it needs adjust.
3. Frequency of A. C. Power supply not exceeding 100Hz;
4. The mechanical load no more than the rated value.

220kV composite suspension insulator Characteristics:
-Small volume and light weight, easy to transport and install
-The superior in performance and high intensity mechanical enhance reliability of power line
-Extraordinary hydrophobic and resistance to contamination
-Long-duration resstance aging and leakage tracking.
