Strain Post Insulator give protection in the event of accidentally broken live wire that can accidentally energizing a stay wire and remaining in contact with line which doesn`t trip.


1.The ceramic is under compression rather than tension, which takes advantage of ceramic's greater compressional strength
2.If the ceramic breaks the two wire loops are still linked and will not fall to the ground
3.Very long life, made of inorganic materials and do not age
4.Very reliable, with a proven track record. Over 80 years of experience
