Guy Insulators
Open-End Type

  • Designed specifically for use in RF applications.
  • Manufactured of high quality wet-process electrical grade porcelain. Standard finish is vitreous glaze (brown).
  • Guy insulators are designed to be rugged, resistant to mechanical breakage, and have zero moisture absorption.
  • Cable groove approaches to the hole are designed to minimize cable stresses.
  • For non-critical applications such as breaking up guy wires to minimize re-radiation effects.

Notes:

  1. Recommended Working Load is calculated using a minimum factor of safety (FOS) of 3.
  2. The 60 Hz dry flashover voltages specified are provided for comparison purposes only and cannot be used to determine permissible RF operating voltages, which are dependent on the type of connection used between the guy line and the guy insulator.

Please consult with us when antenna systems over 100 kW are involved or whenever doubt exists regarding the suitability of the insulators for the intended application.
