High-quality insulators that prevent current from returning to the ground through poles and optimally insulate the wire/tape from the ground..
Different models for all situations:
-Traction insulators
-Corner insulators for line start and end
-Angle insulators
-Section insulators
-Insulators for fibreglass poles, iron posts or wooden posts
-Spacers – distance insulators
-Universal nut insulators for string and tape
