Composite crossarm insulators are used for insulation and support of high voltage power lines with power frequency AC voltage 10-35 kV and frequency not exceeding 100 Hz. The insulators should be used in areas with ambient temperature from -40°C to +40°C, and altitude not more than 1,000 m. Execution standard: GB/T 19519-2004 Composite Insulators for AC Overhead Lines with a Nominal Voltage Greater than 1,000 V-Definitions, Test Methods and Acceptance Criteria

Main technical parameters

Model description: FS refers to composite crossarm insulator. In terms of the fraction after dash, the numerator is rated voltage (kV), and the denominator is bending failure load (kN).
